For the past three months, I’ve been talking to Applecare about a throttling issue that I’m having with my 2015 15” rMBP (m370x, 2.5ghz, 512gb): www.reddit.com/r/osx/comments/4rqffi/2015_macbook_pro_badly_throttling_while_running/ www.reddit.com/r/osx/comments/4u0ptw/2015_macbook_pro_severe_cpu_throttling/ www.reddit.com/r/apple/comments/55hats/rmbp_severe_throttling_apple_says_working_as/ My computer suffers severe clockspeed drops under load (CPU speed drops below 1ghz are common when using Final Cut or Motion), but I can’t seem to get Apple to acknowledge that there’s an issue. In real-world terms, my laptop often renders FCPX projects more slowly than a coworker’s 13” rMBP. I dropped my computer off at the Apple Store on Saturday, alongside all the documentation I posted posted on reddit about a week ago. This afternoon I was told, again, that my issue wouldn’t be resolved. The explanation I received is that the throttling is considered to be “expected behaviour”. I’ve brought my computer to an Apple Store twice before, and I’ve had two months of conversations with Apple Support over the Internet. Here’s a link to some of the documentation I’ve sent Apple, and to some of the conversations I’ve had with Apple employees. Ultimately, I’m looking for a logic board swap or a replacement unit. Barring that, I’m going to have to sell this computer on Craigslist and use that money to buy a new unit (the same SKU). I’ve heard from several users that the issue might be related to excessive thermal pasting, so I might repaste the CPU/GPU first. I’m a video editor and I’m travelling with a news production team to India in a few weeks, so I need to get this resolved within the next ten days or so. Is there any way I can resolve this through Apple?
