Apple is rolling out an update to the 2018 MacBook Pros that it says should fix the controversial overheating issue experienced by some users, including prominent tech YouTubers.
The issue was caused by a firmware bug, Apple said.
In a statement to Business Insider on Tuesday, Apple said:
"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."
Apple also cited on the 2018 MacBook Pro product page the testing it performed on its model with a Core i9 processor. It's similar to the testing by Dave Lee in his YouTube video that kickstarted the controversy.
Hopefully, this means that the Core i9 model of the 2018 MacBook Pro — as well as other 2018 models — shouldn't throttle their performance under heavy loads and that users can enjoy the full potential of the chips inside their MacBook Pros.
- A prominent tech YouTuber says everyone is wrong about Apple's new Core i9 MacBook Pro controversy, and he's right — to an extent
- This YouTube video shows that you have to put the new $2,800 MacBook Pro in a freezer to get it to work properly
- Apple fans are returning their new MacBook Pros that cost a minimum of $2,800 because they can't reach the advertised speeds
