Owen Williams, writing for Motherboard: The pursuit of thinner, lighter laptops, a trend driven by Apple, coinciding with laptops replacing desktops as our primary devices means we have screwed ourselves out of performance -- and it's not going to get better anytime soon. Thermal throttling is not something that Apple alone suffers from: every laptop out there will face thermal constraints at some point, but whether or not that's perceivable depends on a number of different variables including form factor and cooling capacity. When you're shopping for a laptop, you'll notice that manufacturers like Apple use phrases like "Turbo Boost" and "Up to 4.8 GHz" without really explaining what that means. The 4.8 GHz processor clock speed, which Apple quotes for the 15-inch MacBook Pro, is a 'best case' processor speed that's only achieved in short bursts when your computer requests it, subject to a number of conditions.

If you're playing a game like Fortnite, for example, the game will request your processor provide faster performance, and the processor will attempt to increase its operating frequency gradually to deliver the maximum available performance within the thermal envelope of your machine. That maximum is restricted by both power and thermal limits, which is where we run into issues: laptops tend to get hot because they're thinner, with limited space to dissipate that heat through the use of fans and heatsinks.

An anonymous reader shares a report: In 2016, when Apple introduced the first MacBook Pro with Touch Bar models, the repair experts at iFixit discovered the notebooks have non-removable SSDs, soldered to the logic board, prompting concerns that data recovery would not be possible if the logic board failed. Fortunately, that wasn't the case. Apple has a special tool for 2016 and 2017 models of the MacBook Pro with Touch Bar that allows Genius Bars and Apple Authorized Service Providers to recover user data when the logic board fails, but the SSD is still intact. [...] But, unfortunately, it appears the tool will not work with the latest models.

Last week, iFixit completed a teardown of the 2018 MacBook Pro, discovering that Apple has removed the data recovery connector from the logic board on both 13-inch and 15-inch models with the Touch Bar, suggesting that the Customer Data Migration Tool can no longer be connected. MacRumors contacted multiple reliable sources at Apple Authorized Service Providers to learn more, and based on the information we obtained, it does appear that the tool is incompatible with 2018 MacBook Pro with Touch Bar models. Multiple sources claim that data cannot be recovered if the logic board has failed on a 2018 MacBook Pro. If the notebook is still functioning, data can be transferred to another Mac by booting the system in Target Disk Mode, and using Migration Assistant, which is the standard process that relies on Thunderbolt 3 ports.

iFixit tore apart the new 2018 MacBook Pro keyboard to see how well the silicone membrane works to protect the butterfly mechanism from dust and debris. After showering a 2017 and 2018 MacBook Pro in dust particles, the repair site found the newer generation holds up surprisingly well. 9to5Mac reports: As shown in the photo, the blue paint particles coat the outside of the keycaps and the edges of the membrane, but the silicon covers stop most of the particles from getting into the key mechanism -- which is what causes the sticky key issues on the previous models. However, the silicon covers have to have holes in them to allow the keycap clips to attach. Naturally, dust can and will get through these holes over time. iFixit placed some sand particles into the "danger zones" of the keycaps, and confirmed the keys will break/become-unreliable when that happens, just like the second-generation butterfly keys. The non-cocooned 2017 keyboard was "almost immediately flooded" in the particles, unsurprisingly. Clearly, the 2018 model is greatly improved in regard to reliability, but it remains to be seen just how much better it is in real-world use. Over time, you only need a couple specks of dust to get in the keycaps and the keys will get stuck. It's just the chances of dust getting in are greatly reduced with the 2018 models.

Last week, Apple announced new MacBook Pros, including a 15-inch model that supports Intel's 6-core 2.9GHz i9 processor. YouTube Dave Lee managed to get his hands on this top-of-the-line device early and run some tests, revealing that the laptop gets severely throttled due to thermal issues. 9to5Mac reports: Dave Lee this afternoon shared a new video on the Core i9 MacBook Pro he purchased, and according to his testing, the new machine is unable to maintain even its base clock speed after just a short time doing processor intensive work like video editing. "This CPU is an unlocked, overclockable chip but all of that CPU potential is wasted inside this chassis -- or more so the thermal solution that's inside here," says Lee.

He goes on to share some Premiere Pro render times that suggest the new 2018 MacBook Pro with Core i9 chip underperforms compared to a 2017 model with a Core i7 chip. It took 39 minutes for the 2018 MacBook Pro to render a video that the older model was able to render in 35 minutes. Premiere Pro is not well-optimized for macOS, but the difference between the two MacBook Pro models is notable. Lee ran the same test again with the 2018 MacBook Pro in the freezer, and in cooler temperatures, the i9 chip was able to offer outstanding performance, cutting that render time down to 27 minutes and beating out the 2017 MacBook Pro.

After determining that a "small percentage" of 2015-2017 MacBook and MacBook Pro keyboards may experience sticky keys, Apple initiated a Keyboard Service Program. The company has been servicing affected keyboards for free, but the fix doesn't guarantee the problem won't emerge again. The new 2018 MacBook Pros feature third-generation keyboards that are intended to prevent the keys from getting stuck. "For this reason, some customers have been hoping that Apple will start swapping out second-generation keyboards with third-generation keyboards, as part of its service program, but MacRumors has learned that isn't the plan." From the report: When asked if Apple Stores and Apple Authorized Service Providers will be permitted to replace second-generation keyboards on 2016 and 2017 MacBook Pro models with the new third-generation keyboards, if necessary, Apple said, no, the third-generation keyboards are exclusive to the 2018 MacBook Pro. Hopefully, in that case, it means that Apple has quietly tweaked the second-generation keyboard to be more reliable. It wouldn't really make sense for Apple to replace keyboards with ones that are just as prone to break again, especially if the third-generation keyboards offer a fix.

One possibility is that the third-generation keyboards aren't backwards compatible with 2016 and 2017 MacBook Pro models to begin with. The keyboard is actually one part of a larger component called the "top case," which also has a glued-in battery, and the internal design could be tweaked in 2018 models.

Last week, Apple refreshed the 13-inch and 15-inch MacBook Pro models, bringing newer Intel processors and quieter keyboards. The new 13-inch MacBook Pro also just so happens to feature the fastest SSD ever in a laptop, according to benchmarks from Laptop Mag. Mac Rumors summarizes the findings: The site's tests were performed on the $2,499 13-inch MacBook Pro with Touch Bar equipped with a 2.7GHz quad-core 8th-generation Core i7 processor, 16GB RAM, Intel Iris Plus 655, and a 512GB SSD. A file copy test of the SSD in the new MacBook Pro, which Apple says supports sequential read speeds of up to 3.2GB/s and sequential write speeds up to 2.2GB/s, led Laptop Mag to declare the SSD in the MacBook Pro "the fastest ever" in a laptop. Higher capacity SSDs may see even faster speeds on disk speeds tests. A BlackMagic Disk Speed test was also conducted, resulting in an average write speed of 2,682 MB/s.

On a Geekbench 4 CPU benchmark, the 13-inch MacBook Pro earned a score of 18,055 on the multi-core test, outperforming 13-inch machines from companies like Dell, HP, Asus, and Microsoft. That score beats out all 2017 MacBook Pro models and is faster than some iMac configurations. 15-inch MacBook Pro models with 6-core 8th-generation Intel chips will show even more impressive speeds. With that said, the 13-inch MacBook Pro didn't quite measure up to other machines when it came to GPU performance. "The 13-inch 2018 MacBook Pro uses Intel's Iris Plus Graphics 655 with 128MB of embedded DRAM and was unable to compete in a Dirt 3 graphics test, getting only 38.8 frames per second," reports Mac Rumors. "All Windows-based machines tested offered much better performance."

Apple has worked with cinema company Blackmagic on an external GPU based around an AMD Radeon Pro 580 graphics card with 8GB of DDR5 RAM. The Blackmagic eGPU features "an HDMI port, four USB 3.1s and three Thunderbolt 3s, the latter of which makes it unique among these peripherals," reports TechCrunch. From the report: The company says the on-board cooling system operates pretty quietly, which should fit nicely alongside those new, quieter MacBook keyboards. Many developers will no doubt prefer to configure their own, but for those who want an easier solution for playing resource-intensive games or graphics rendering on with a MacBook, this is a fairly simple solution. The [$699] eGPU is available now through Apple's retail channels.

After multiple lawsuits have been filed over the butterfly-switch keyboards found on the MacBook Pro and MacBook lineups, you would think Apple would fix this issue by including a keyboard in the new MacBook Pros that can't be damaged by a little dust. Unfortunately, while the new 2018 MacBook Pro does have an updated third-generation keyboard, Apple tells CNET it doesn't include any new engineering or tweaks to address the sticky key issue. CNET reports: Instead, the third-generation keyboard's tweaks are about making it quieter. In a brief typing test, CNET's long-time MacBook reviewer Dan Ackerman says it isn't "whisper-quiet" but does "lack the sharp click of the previous design." Technically, Apple has admitted only that "a smaller percentage of the keyboards in certain MacBook and MacBook Pro models" have demonstrated the sticky key issue. If you buy one, you may likely never have that problem. But it's worth noting that when the company launched its free keyboard repair program in June, it made literally every single model of MacBook Pro with the "butterfly switch" keyboard eligible.

After announcing new MacBook Pro models today, Apple has removed the 2015 MacBook Pro from the Mac section of its website. Ars Technica reports: Beloved by many, the 2015 MacBook Pro had a number of features that have since been changed or have disappeared entirely from new MacBook Pro models. Arguably the most polarizing among these tweaks is the butterfly keyboard -- the 2015 MacBook Pro predates that mechanism, making its traditional keyboard a preferred alternative for many users. The 2015 MacBook Pro also contained legacy ports that Apple has since abandoned in the newest models: USB-A, HDMI, and Thunderbolt 2 ports, and an SD card slot. All of the newest MacBook Pros exclusively feature Thunderbolt 3 ports, which some will appreciate but all will scowl at when they're forced to buy multiple dongles to connect legacy accessories. Currently, Apple has a few 2015 MacBook Pro models listed in its online clearance section, but it's likely that Apple will not have more to sell after those are gone.

Apple said on Thursday it is refreshing the 13-inch and 15-inch MacBook Pro models. Neither machines are getting major redesigns, but the innards are getting a spec update. For starters, both the models are powered by the 8th-generation Intel processors and house more cores than before -- a maximum of six cores on the 15-inch model (compared to four in last year's models) and four in the 13-inch model (compared to two). That means faster performance for many use cases. Maximum SSD capacity is also doubled, and the MacBook Pro line offers DDR4 RAM for the first time. ArsTechnica: The laptops also borrow some features from the iMac Pro and the iPad Pro -- the T2 chip and True Tone, respectively -- and feature a revised butterfly keyboard, the third generation of the design Apple introduced in 2016 (the revision is a little more significant this time around). Apart from those tweaks to the keyboard, the basic design of the MacBook Pro is unchanged. The top configuration of the 15-inch model includes an 8th-generation, six-core Intel Core i9 CPU clocked at 2.9GHz. Six-core Intel Core i7 processors are also options. The 2017 iteration of the MacBook Pro featured DDR3 memory with a maximum configuration of 16GB. This time, it's DDR4, and the maximum is 32. The faster memory uses more energy, so a bigger battery is now included -- but Apple's battery life estimate remains the same as last year's. The GPU in the top standard configuration is listed as an AMD Radeon Pro 555X.

The 13-inch model has different specs, of course. It still only offers integrated Intel graphics, for one thing -- Intel Iris Plus 655, this time with 128MB of eDRAM. But the maximum number of cores are again doubled -- in this case to four -- in 8th-generation Intel Core i5 or Core i7 CPUs, which run at up to 2.7GHz. Maximum SSD capacity is also doubled; it's now 2TB. The maximum memory is still 16GB. Apple claims the 13-inch model is up to twice as fast as its predecessor, though it will of course depend on the application. ArsTechnica says the keyboard on the new MacBook Pro models, though look similar to the one in the predecessor lineup, feel a little different to type on. The price of 13-inch starts at $1,799 while the 15-inch starts at $2,399.

According to a note shared by reliable Apple analyst Ming-Chi Kuo, Apple is planning to refresh a number of its computing product lineups later this year. Via MacRumors: iPhone: There are three iPhones in the works, two OLED models in 5.8 and 6.5-inch sizes and one LED model that will be available in a 6.1-inch size.
iPad: Apple is working on two new 11 and 12.9-inch models that are equipped with a full-screen design and no Home button, with Apple to replace Touch ID with Face ID.
Mac mini: Processor upgrades expected.
MacBook Pro: Processor upgrades expected.
MacBook: Processor upgrades expected.
New Low-Priced Notebook: Kuo believes Apple is designing a new low-priced notebook. He originally said that this would be in the MacBook Air family, but now has changed his mind. Previous rumors have suggested this machine could be a 12-inch MacBook.
iMac: Significant display performance upgrade alongside a processor upgrade.
Apple Watch: Two new models in sizes that include 1.57 inches (39.9mm) and 1.78 inches (45.2mm) with an enhanced heart rate detection feature.

The new tallest building on the San Francisco skyline -- and the tallest building in America west of the Mississippi -- includes a nine-story electronic sculpture that's been called the tallest piece of public art on Earth. It uses 11,000 LED bulbs reflected off the tower-topping aluminum panels -- each pixel created by a set of red, green, blue and white lights controlled by 8-bit PIC microcontrollers. "On a clear night, the show is visible for 30 miles," reports IEEE Spectrum.

Slashdot reader Tekla Perry shares their article about "the technology involved in the light show at the top of Salesforce Tower. Electrical engineer and artist Jim Campbell explains it all -- and how the window-washer problem stumped him for nearly a year." "[O]n the 62nd floor, a central PC-based computer runs Ubuntu Linux, sending instructions to a communications control system that splits the data and sends it at 11 Mbit to the 32 enclosures using a custom communications protocol... We will capture images throughout the day, sending them to Amazon's cloud, and run some algorithms designed to identify visual interesting-ness. For example, at its simplest, when we look at the sky, if it's all blue, it's boring, if it's all white, it's boring, if it has white and blue it is likely to be interesting. We'll chose the best half hour of the day at each camera, based on movement and color, to display...."

And finally, when the main display shuts down late at night, another system designed by Campbell will kick in. In this static display, a set of 36 white LEDs will create a three-dimensional constellation of lights that will look like stars. "It's quieter, it has a random aspect to it," he says.
"Since construction started, the tower has emerged as an icon of the new San Francisco -- techie, ambitious, perhaps a little grandiose," writes the New Yorker, capturing the moment when Campbell finally unveiled his four-year project -- while fighting stomach flu and a chest cold, on a night which turned out to be prohibitively foggy. The executive vice-president of Boston Properties told him cheerily, "Jim! Look on the brighter side. We've got every night for the rest of our lives."

"There was a long silence from the people on the terrace. The fog was thick. At last, someone exclaimed, 'Woo-hoo!,' and a volley of cheers followed." Although the colors they were seeing came from the celebratory fireworks and not from Jim's light sculpture.

Are there any San Francisco-area Slashdotters who want to weigh in on the Salesforce Tower?

Casey Johnston, writing for The Outline: At long last, Apple admitted to its customers that its MacBook and MacBook Pro keyboard designs are so flawed and prone to sticking or dead keys, as originally reported by The Outline in October, and that it will cover the cost of repairs beyond the products' normal warranty. The admission comes after the company has been hit with no fewer than three class action lawsuits concerning the computers and their ultra-thin butterfly-switch keyboards. While the repair and replacement program covers costs and notes that Apple will repair both single keys as well as whole keyboards when necessary, it doesn't note whether the replacements will be a different, improved design that will prevent the problem from happening again (and again, and again).

Quentin Carnicelli, the chief technology officer at Rogue Amoeba, a widely-reputed firm that produces several audio software for Apple's desktop operating system: With Apple recently releasing their first developer beta of MacOS 10.14 (Mojave), we've been installing it on various test machines to test our apps. The inevitable march of technology means Mojave won't install on all of our older hardware. There's no shock there, but the situation is rather distressing when it comes to spending money to purchase new equipment. Here is the situation, as reported by the wonderful MacRumor's Buyers Guide: At the time of the writing, with the exception of the $5,000 iMac Pro, no Macintosh has been updated at all in the past year. Here are the last updates to the entire line of Macs: iMac Pro: 182 days ago, iMac: 374 days ago, MacBook: 374 days ago, MacBook Air: 374 days ago, MacBook Pro: 374 days ago, Mac Pro: 436 days ago, and Mac Mini: 1337 days ago.

Worse, most of these counts are misleading, with the machines not seeing a true update in quite a bit longer. The Mac Mini hasn't seen an update of any kind in almost 4 years (nor, for that matter, a price drop). The once-solid Mac Pro was replaced by the dead-end cylindrical version all the way back in 2012, which was then left to stagnate. I don't even want to get started on the MacBook Pro's questionable keyboard, or the MacBook's sole port (USB-C which must also be used to provide power). It's very difficult to recommend much from the current crop of Macs to customers, and that's deeply worrisome to us, as a Mac-based software company.

To celebrate its 14th birthday, Phoronix.com used a 15-inch MacBook Pro to run system benchmarking tests on the following operating systems:

- Windows 10 Pro

- The latest macOS 10.13 High Sierra

- Windows 10 Windows Subsystem for Linux (WSL) using Ubuntu 18.04

- Ubuntu 18.04 LTS with the Linux 4.15 kernel, GCC 7.3.0, and an EXT4 file-system.

- Clear Linux 22780 with the Linux 4.16 kernel, GCC 8.1.1, and EXT4.

- Fedora Workstation 28 with updates is the Linux 4.16 kernel, GCC 8.1.1, and EXT4.

- OpenSUSE Tumbleweed with the Linux 4.16 kernel, GCC 7.3.1, and default file-system configuration of Btrfs root file-system with XFS home partition.

The results? When it came to outright wins and losses, Clear Linux 22780 was the front-runner 59% of the time followed by macOS 10.13.4 finishing first 21% of the time and then Fedora Workstation 28 with winning 10% of the time.

For losses, to little surprise considering the I/O overhead, Windows 10 was in last place 38% of the time followed by Ubuntu 18.04 being surprisingly the slowest Linux distribution 30% of the time on this 2016 MacBook Pro.
The article also reminds readers that "For those looking for a Linux laptop, there are plenty of better options..."

Stephen Shankland, writing for CNET: With its next-generation MacOS Mojave software, Macs will be able to run some apps written for iPhones and iPads, a big new step in bringing the two technology platforms closer together. Craig Federighi, Apple's senior vice president of software engineering, announced the change Monday at Apple's Worldwide Developer Conference in San Jose. And he said Mojave will include four apps Apple itself brought from its iOS mobile software to MacOS: Home, Stocks, News and Voice Memo. "There are millions of iOS apps out there, and we think some of them would look great on the Mac," Federighi said. For now, it's only Apple that has the ability to move iOS apps to MacOS. But that'll change in 2019.

On Friday, Apple was hit with a class action lawsuit over the butterfly-switch keyboards, found on the current generation MacBook Pro and MacBook lineups, that have plagued its customers since they were released in 2015. The suit, filed in the Northern District Court of California, alleges that Apple "promoted and sold laptops it knew were defective in that they contain a keyboard that is substantially certain to fail prematurely," The Outline reports, and that selling these computers not only directly to its customers but also to third party retailers constitutes a violation of good faith. From the report: The Outline was the first outlet to substantially cover the magnitude of the issue, writing that Apple Geniuses responsible for diagnosing and repairing these Apple computers would benevolently attribute dead keys and double-spacing spacebars to a "piece of dust" stuck under the keyboard. Under Apple's warranty, Geniuses might offer to replace the entire top case of the computer, a process that takes about a week. Out of warranty, it costs about $700 to replace this part on a MacBook Pro. Apple has declined repeatedly to comment on the issue, but directs sufferers to a support page that instructs users how to tilt the computer at an angle, blow canned air under the malfunctioning keys, light candles arranged in the shape of a pentagram, and recite an incantation to Gaia in hopes of fixing their machines. Earlier this month, users kickstarted a petition on Change.org that calls on Apple to recall MacBook Pro units released since late 2016 over the defective keyboard. The petition has garnered about 20,000 signatures. Widely respected iOS developer and Apple commentator Marco Arment tweeted on the news, "We can't know for sure that Apple knew the 2016 keyboards were defective and sold them anyway. But it's hard to see how they couldn't have known. They were released 18 months earlier in the 12" MacBook, and those had the same problems with high failure rates from the start."

Apple might have some explaining to do if a recent petition against its MacBook Pro continues to gain steam. From a report: A petition surfaced this week on Change.org that calls on Apple to recall MacBook Pro units released since late 2016 over what the petition author Matthew Taylor calls a "defective keyboard." The petition seeks 7,500 signatures and as of this writing, it's closing in on 6,200. Judging by the sheer number of signatures coming in each minute, it shouldn't take long for it to hit the goal.

"Apple, it's time: recall every MacBook Pro released since late 2016, and replace the keyboards on all of them with new, redesigned keyboards that just work," the petition reads. It goes on to say that "every one of Apple's current-gen MacBook Pro models, 13-inch and 15-inch, is sold with a keyboard that can become defective at any moment due to a design failure."

Last year, a report outlining what it described as a major flaw in Apple's current MacBook Pro lineup became a talking point in the industry. The issue was that a piece of dust could render keys on the MacBook Pro lineup useless, and that Apple had no idea how to fix it. Casey Johnston, writing for The Outline: MacBook Pro's keyboard keys stopped working if a single piece of dust slipped under there, and more importantly, that neither Apple nor its Geniuses would acknowledge that this was actually a problem. Today, Best Buy announced it is having a significant sale on these computers, marking them hundreds of dollars off. Interesting. Still, I'd suggest you do not buy them. Since I wrote about my experience, many have asked me what happened with the new top half of the computer that the Apple Geniuses installed, with its pristine keyboard and maybe-different key switches. The answer is that after a couple of months, I started to get temporarily dead keys for seemingly no reason. Again. Longtime widely respected commentator Jason Snell says, "I know that we Apple-watchers sit around wondering if Apple will release new laptops with new keyboards that don't have these issues, but Apple's relative silence on this issue for existing customers is deafening. If these problems are remotely as common as they seem to be, this is an altogether defective product that should be recalled."

"After years of phones, laptops, tablets, and TV screens converging on 16:9 as the 'right' display shape -- allowing video playback without distracting black bars -- smartphones have disturbed the universality recently by moving to even more elongated formats like 18:9, 19:9, or even 19.5:9 in the iPhone X's case," writes Amelia Holowaty Krales via The Verge. "That's prompted me to consider where else the default widescreen proportions might be a poor fit, and I've realized that laptops are the worst offenders." Krales makes the case for why a 16:9 screen of 13 to 15 inches in size is a poor fit: Practically every interface in Apple's macOS, Microsoft's Windows, and on the web is designed by stacking user controls in a vertical hierarchy. At the top of every MacBook, there's a menu bar. At the bottom, by default, is the Dock for launching your most-used apps. On Windows, you have the taskbar serving a similar purpose -- and though it may be moved around the screen like Apple's Dock, it's most commonly kept as a sliver traversing the bottom of the display. Every window in these operating systems has chrome -- the extra buttons and indicator bars that allow you to close, reshape, or move a window around -- and the components of that chrome are usually attached at the top and bottom. Look at your favorite website (hopefully this one) on the internet, and you'll again see a vertical structure.

As if all that wasn't enough, there's also the matter of tabs. Tabs are a couple of decades old now, and, like much of the rest of the desktop and web environment, they were initially thought up in an age where the predominant computer displays were close to square with a 4:3 aspect ratio. That's to say, most computer screens were the shape of an iPad when many of today's most common interface and design elements were being developed. As much of a chrome minimalist as I try to be, I still can't extricate myself from needing a menu bar in my OS and tab and address bars inside my browser. I'm still learning to live without a bookmarks bar. With all of these horizontal bars invading our vertical space, a 16:9 screen quickly starts to feel cramped, especially at the typical laptop size. You wind up spending more time scrolling through content than engaging with it. What is your preferred aspect ratio for a laptop? Do you prefer Microsoft and Google's machines that have a squarer 3:2 aspect ratio, or Apple's MacBook Pro that has a 16:10 display?
