A bug fix is included in today’s macOS High Sierra 10.13.6 Supplemental Update and is recommended. “There is a missing digital key in the firmware that impacts the thermal management system.”įollowing 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. The bug affects every new generation of the MacBook Pro, including both the 13-inch and 15-inch sizes and all of the Intel processor configurations. In a call with The Verge, representatives said that the throttling was only exhibited under fairly specific, highly intense workloads, which is why the company didn’t catch the bug before release. The company also apologized, writing, “We apologize to any customer who has experienced less than optimal performance on their new systems.”Īpple claims that it discovered the issue after further testing in the wake of Lee’s video, which showed results that Apple hasn’t seen in its own testing.

Apple has acknowledged that thermal throttling is a real issue caused by a software bug, and it’s issuing a software update today that is designed to address it. They run so hot, in fact, that the very fancy 8th Gen Intel Core processors inside them were throttled down to below their base speed. For a week, we have been seeing reports that the newly released MacBook Pros run hot, which all kicked off after this video by Dave Lee.
