OpenCore Legacy Patcher Project Brings macOS Sonoma Support To 16-Year-Old Macs (arstechnica.com) 32

An anonymous reader quotes a report from Ars Technica: When Apple decides to end update support for your Mac, you can either try to install another OS or you can trick macOS into installing on your hardware anyway. That's the entire point of the OpenCore Legacy Patcher, a community-driven project that supports old Macs by combining some repurposed Hackintosh projects with older system files extracted from past macOS versions. Yesterday, the OCLP team announced version 1.0.0 of the software, the first to formally support the recently released macOS 14 Sonoma. Although Sonoma officially supports Macs released mostly in 2018 or later, the OCLP project will allow Sonoma to install on Macs that go back to models released in 2007 and 2008, enabling them to keep up with at least some of the new features and security patches baked into the latest release.

OpenCore Legacy Patcher Project Brings macOS Sonoma Support To 16-Year-Old Macs

  • Because they can.

  • Will they make a reverse Rosetta like layer to keep Intel Macs going?

      I rather doubt that will be possible. At least not with the resources of a community project. I would love to be wrong though.

        It has already been done, thanks to QEMU. Actualy, there is a FOSS project called TUM (Turing Universal Machine) that allows an intel MAC to run ARM MacOS (and Vice-versa).

    • I just assume that that's when the support will end. I do hope they make a patch for apple silicon macs once Apple starts dropping support for M1 Macs.
  • I will upgrade my prehistoric intel machines the first chance I get.
    • I wonder if I can upgrade my Dual Xeon Mac Pro.
      Actually I don't really care. I just have it for a few old Mac games and it never goes anywhere near any network, so there really isn't any point in upgrading to a newer OS. The accomplishment by the OLCP team is impressive though.

    As an user of OCPL, i am very grateful to the team, and the splendid job they do.

    A piece of advice though: If your MacOS is still receiving security patches, from a security standpoint your are better off staying there, even if it is an older version of MAcOS that is rewceiving security patches but "no all vulnerabilities are patched" than to go to OCLP in order to collect patches for every single vuln.

    You see, compared to the standard process of security patching in MacOS (and even compared to the install process of a new version of MacOS) , OCPL is significantly more inconvenient to install (is not dificult, but rahter involved, laborious and cumbersome). Which means, that we as humans, will sometimes neglect the task, and skip an install or two, leaving our machines vulnerable.

    So, if your Mac has stoped receiving security updates, or if you want to use the latest and greatest features of a new MacOS, OCLP is the way to go. But if you want the most security posible (given that apple does guarantee to patch every single vuln in older versions), stick to plain vanilla macOS, even if it is an older version, as long as apple is releasing security patches for it.

      Sounds like jailbreaking an iPhone. Keeping it jailbroken and secure at the same time is tedious as best.

      Said every computer user ever. Especially the ones that still believe in the fantasy world that Jobs described in that multiple decades old speech, before the the term "Internet" was even a part of the average person's vocabulary.

      Some of us however like the challenge. Discouraging others from even attempting it, however is fool hardy at best. They might just become the person that develops your future iDevices a few decades from now.

  • Really curious to see how usability is.

    I've got an old 2010 13" Macbook Air that's sititng in a drawer, and it had questionable usability when I put it there (due to out of date software, but just the general slowness of the hardware). Now, it looks like OpenCore supports it, but... well, not sure how usable it'll be with 4GB of RAM (or whatever it has).

    • I have a 2014 mbp max out and tried ventura with OCLP and it ran like crap. Still stuck on monterey.
      • I have a 2013 Mac mini maxed out runs windows 10 like a boss for daily driver stuff... even do some cad work on it from time to time

        Other than finding some wonky wifi/Bluetooth drivers worked direct off the USB stick (then I upgraded that card anyway so no big deal)

    • I wouldnt bother. Mac Airs where never at the top of the heap for performance, although they've tended to be better behaved than their chromebook or budget-pc counterparts. Running an operating system that assumes hardware from the last 5 years on a bottom-rung machine from 13 years ago isn't a strategy that'll produce a machine thats pleasant to use, particularly with the GPU assumptions baked into modern mac os's

    • Well, I have a new Acer Aspire 3 and an MacBook Air 2014.
      The Aspire runs for now (and that will end soon) Windows 11 Home Edition (Never had a worse experience as a user with a computer, and as an Admin: simple said: what the fuck!)

      The MacBook runs Mojave, could upgrade to a newer one, but I do not like to change in a winning team.

      No idea what speed requirements you have ... but my old MacBook is faster in every regard than my new Acer.

      I always "kind of" hated Windows. But now the "kind of" dropped, what a

  • I'm not so certain that running Sonoma on old hardware is such a good idea. I recently upgraded my shiny, month-old M1 iMac to Sonoma. Big mistake! Aside from the fact that it still have has the incredibly stupidly designed and badly thought out DVD player app inherited from the rewrite performed for Mojave a few years ago, and now it has issues when playing DVD's. However, those problems are due to the OS itself, not the player because they also occur with VLC. These problems did not exist with Ventu

  • I'm using Open Core Legacy Patcher to run Ventura on a MacBook "Mid 2010, 2.4 GHz Intel Core 2 Duo". Overall, very usable. A bit more occasional lags than with High Sierra on the same hardware. A few rough edges. The "Metal" API isn't supported: the only app that's stopped is GarageBand. BlueTooth doesn't work. Not sure if that's OCLP or my ancient MacBook. And System Settings keyboard shortcuts won't let you change the shortcuts. Other than that, all OK so far. I did installation to a new SSD (this MacBook
  • New OS probably takes up a much larger room on your HD. You need to make sure it fits and have enough RAM for it to operate. As other commenters said, it makes it worse than current OS. Mute point for me, I run my Macs til they die then replace them.
  • I have an EFI32 based Linux Installer that works perfectly. I've used it since 2013. EFI32 support is lacking and basically you are on your own. My old MacPro isn't my primary computer but it still works, does not lock up, and supports the old AMD GPUs just fine. It looks like I can update my 2016 Tin Can MacPro now.
