There have been many rumors that the super slim design of the new MacBook Pro is refraining the Intel Core i9 processor. However, Apple recently announced that it’s a software bug that’s causing the heat issues in new MacBook Pros. In a statement released by Apple, the tech giant admitted that it’s a software bug and fix has been released and is available for the MacOS users immediately. It’s not just for the top-end Core i9 15-inch models. The bug is affecting all the new set of MacBook Pros. However, Apple is still standing on its original notion that the 15-inch models are over 70% faster than the previous generation of MacBook Pros and the 13-inch models are two times faster.

What’s the Software Bug in New Apple MacBook Pros?

This speed throttling issue was first found and exposed by a YouTuber named Dave Lee just after a couple of days after the launch of new MacBook Pros. Dave tested the high-end 15-inch model MacBook Pro with the i9 processor by running an Adobe Premiere Pro. He found out that it’s underperforming and surprisingly 2017 Macs are performing better than the new MacBook Pros. He had also discovered that throttling levels in the new MacBook Pros are unbelievable and unacceptable.

Apple was quick and reached out to Dave to work around this issue. First of all, they studied his workflow to find out the source of the issue. Apple found out that digital key was missing in the new MacBook Pro models which are impacting the heat management system which is steering down that clock speeds because of heavy thermal loads. Apple released a supplemental update and the fix seems to be fixed successfully. Apple also issued an apology to its customers who had to face troubles and underperformance with their new 2018 MacBook Pros. It’s strongly recommended for all the new MacBook Pro owners to install the bug fix immediately to improve the performance of their computers. Dave Lee, who discovered these speed throttling issues found that bug fix is quite useful and has efficiently fixed the underperformance issues.

Apple must be appreciated for the quick action and efficiently fixing the bug. It just took 2 weeks for Apple to realize the issue and release a bug fix. Their words of apology are wonderful, and they have the strong brand loyalty for a reason. The new bug fix stopped the CPU throttling successfully, and even the CPU clock frequency and thermal load are quite stable. You can also test it by setting a game to maximum detail mode or by playing a 4K video encode. The early results are promising, and we recommend all the new MacBook Pro users to update their software immediately. Speed throttling and thermal loads affect the CPU health very badly.

Now, the week full of drama over the new Macs comes to an end with an efficient bug fix. Let us know in the comments section if you have any troubles installing the new bug fix. Keep visiting our blog as we continue to post more tests and news about the Apple’s new software patch.
