Today I was informed by Apple support that they won’t be fixing a throttling issue with my 2015 15” rMBP (m370x, 2.5ghz, 512gb). Whenever I put any real TDP load on the system, it will throttle badly: Trine (FPS goes from 60 to >30, reported CPU speed drops to 0.8ghz) World of Warcraft (~20fps in Stormwind @ lowest graphics preset, reported CPU speed at 0.8ghz) Handbrake (export slows considerably, reported CPU speed at ~1.7ghz) Uniengine Heaven Benchmark (I scored 18.9FPS over the duration of the bench, MacWorld scored 35 FPS at similar settings. Reported CPU speed at 0.8ghz) I’m employed full-time doing Motion/FCPX work and this computer is very difficult to use with those programs. Here’s what it looks like when I try to open my FCPX projects on this computer: Not exactly usable. (And here are some videos of people running demanding programs on the same SKU I have, without apparent throttling.) I’ve been in communication with Apple for two months about this issue. At the behest of Apple support, I’ve deleted many of the third-party programs on my computer, and removed all third-party kexts. I’ve also tried installing fresh copies of several different OSX releases. All the while my computer continues to throttle in the exact same way. And today, I was told in-person that Apple won’t be trying anything else to fix my computer. I’m a technically literate and patient person, but I’m very frustrated. Apple has refused to acknowledge any kind of problem when it seems likely there’s a hardware issue. Here’s a partial log of my communications with Apple. What the hell am I supposed to do?
