Apple Releases Fix for Throttling on New MacBook Pro

Posted July 24, 2018 at 5:27pm by iClarified
Apple has announced a supplemental update to macOS High Sierra to address issues with throttling on the new MacBook Pro.

Shortly after its release, YouTuber Dave Lee discovered that the new Core i9 MacBook Pro overheats under load leading to significant throttling. Issues with throttling have been confirmed by various sources with some reporting "the ultimate root cause of the very bad performance drop during the throttling is not thermal throttling of the CPU, but rather power throttling of the VRM (voltage regulator module)."

Here is Apple's explanation via MacRumors...

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.

Users can download the supplemental update from the Mac App Store. Let us know in the comments if you notice a significant improvement!

Its funny how obvious they are right. If they only knew the joy of something working great even when there is an issue. My windows installed on my parallel is running better than an actually windows machine.

“Better than an actual Windows machine”? Which one? That’s the dumbest comment ever. Hardware is hardware. There isn’t anything different or special about Apple’s computers. They have intel processors, Intel wireless chips, Intel or Nvidia GPU processors, Kingston or Crucial RAM modules etc.. All the same hardware that’s in most PC’s (Windows machine). The differences are in; A) the operating system (OSX) B) the pretty case, box it’s in. which in this case is too small and restricted and lacks proper airflow to effectively cool an Intel i9 processor.
