Retina MacBook Pro’s Latest EFI Update Causing Graphics, Processor Issues For Some Users

Apple’s latest EFI update for the Retina MacBook Pro should be avoided if possible.

If you haven’t already installed Apple’s latest EFI firmware for your 15-inch Retina MacBook Pro, you may want to avoid it for a little while. Users on the Apple Support Communities forum are reporting that the update causes reduced frame rates and processor slowdowns when using graphically-intensive applications.

There are countless threads regarding the issue, with all users reporting that the problem is very inconsistent. It appears to affect MacBook Pros that are waking from sleep mode, or those that are used for gaming and using Windows in Boot Camp. The more graphically-intensive the application is, the bigger the problem.

Many report significant throttling of the processor and graphics processing unit speeds when high temperatures are reaches. According to one user, the speed reduction kicks in around 65°C, and then it drops again at 80°C — temperatures that are harmless to a chip that can withstand up to 105°C, according to Intel.

Electronista reports that some users are speculating that the behavior could be intentional — a “feature” introduced by Apple, designed to eliminate the persistent whine from fans when the computer is placed under heavy load, or to prevent overheating. However, for many users, it’s nothing more than an annoyance.

Have you suffered any of these issues on your Retina MacBook Pro?

    Man…I wanted one, but it looks like rmbp going awol.

    I updated and haven’t had problems. I was working on a high res album cover in Photoshop CS6 last night and it didn’t give me an issue.

    I’ve owned a lot of Macs in my day and my Retina MBP is my favorite by a long shot.

    So someone thought that the user experience would be more severely harmed by a fan sound than by their entire system slowing down when trying to do intense work (playing games.)

    Crazy, right?

    I have one, and it’s not been a problem at all. Admittedly I don’t do much gaming on it, but I’m sure Apple will fix these problems in another update.

    My Google Chrome buzzes whenever I scroll (sometimes!) – on RMBP 15

    in fact, the new update actually solved some of the glitches i’m having with my rMBP 15″. so far i didn’t find any issue with the performance, i’ll try it out later this week with some photoshop-ing and see how it goes.

    I have been having problems with my mbp retina (15″) when playing games in bootcamp. The fps has drastically dropped from 40-50+ in swtor to now being around 10-15fps. I thought perhaps windows was using the intel 4000 instead of the nvidia gpu. But, perhaps this is the issue?

    I should say in mbp’s defence that the fps in swtor was ok up until today… Apple have already had to change its logic board once as the last one failed entirely. I hope i dont have to go through that again.

    Tried the SMC reset this morning. FPS in bootcamp playing SWTOR is back to normal.

    Am very glad I found this article and hope apple are apple to address this asap.
