Apple says software patch will fix the MacBook Pro’s thermal troubles

The latest MacBook Pro has garnered many headlines recently, sadly for all the wrong reasons.

It all started when Dave Lee published a video which showcased how badly a MacBook Pro fitted with an Intel Core i9 processor throttled when under load. Additional videos from notable YouTuber’s Linus Sebastian and Marques Brownlee further showed how badly the CPU throttled though the notebook was still very much usable.

Both Sebastian and Brownlee pointed to the notebook’s form factor as a possible reason for the thermal throttling and subsequent performance dip but now we’ve learned that this is not the case.

According to a statement released by Apple, the performance woes were caused by software. Yes, thermal issues caused by software.

Here’s the statement from Apple via TechCrunch.

Following extensive performance testing under numerous workloads, we’ve identified that there is a missing digital key in the firmware that impacts the thermal management system and could drive clock speeds down under heavy thermal loads on the new MacBook Pro. A bug fix is included in today’s macOS High Sierra 10.13.6 Supplemental Update and is recommended. We apologize to any customer who has experienced less than optimal performance on their new systems. Customers can expect the new 15-inch MacBook Pro to be up to 70% faster, and the 13-inch MacBook Pro with Touch Bar to be up to 2X faster, as shown in the performance results on our website.

The supplemental update for macOS High Sierra is being rolled out today and users are advised to download and install the update as soon as possible.

We must commend Apple for identifying and fixing the issue in little under a week after they were made aware of the problems. Good job folks.

That having been said we’ll be keeping an eye out for news that this patch actually solves the thermal issues and we’ll be sure to bring you that info as soon as we have it.
