I'm desperate. Am I out of options? (2015 rMBP throttling)

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/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?

I have a 13" 2015 rMBP that runs at turbo boost speeds consistently during heavy tasks. I also have a 2011 Mac mini that goes from 2.3GHz to about 1.8GHz under load. I don't think your thermal throttling is normal.

My MacBook Pro throttles under high CPU usage, too. Despite the "Pro" moniker, Apple makes these machines too thin to adequately cool themselves while actually doing pro work.

My new ThinkPad P50 doesn't throttle, FWIW. It's also not as thin as my MacBook Pro, but I don't care.

Canada, eh!
yes, but its a waste of money, and needlessly buying and returning it. Plus buying just to return it, seems kosher
I did this once when I put my machine in for repair and needed one do some work. They were okay with it. If you use your credit card and return it before the end of the billing cycle, there's no money changing hands.

I have a a general idea what might be causing it. Do you have any temperature or smcFanControl pics of your Mac? I need to see those to give a better advice.

I agree....but if a coworker has the same model and specs, then test them both using the same file. It may be the only way to show Apple what is going on, or to see if they are correct for that model.

I guess you'll have to escalate the issue even higher. Find who's in charge of the people that didn't help you. Email them. If there's no answer, email someone else. ****ing email Tim Cook twice a day if it's necessary. You've paid a premium price for a premium product to a company that's becoming lazy and careless.
