MacBook Pro. Among them: A stripped screw near the subwoofer enclosure and an unlocked ZIF (zero insertion force) socket for the IR (infrared) sensor. '[These] should not be things found inside a completely unmolested computer with an $1,800 base price,' iFixit said in the teardown description. iFixit also spotted an unusual amount of thermal paste applied to both the CPU and the GPU. 'Holy thermal paste! Time will tell if the gobs of thermal paste applied to the CPU and GPU will cause overheating issues down the road,' iFixit said. The refreshed MacBook Pro models launched last Thursday in what one analyst called a 'ho-hum' upgrade."
