Apple targets thermal performance issues 2018 MacBook Pros with software update

Performance issues affecting the latest Apple’s 2018 MacBook Pro discovered last week have been identified as a software flaw in the system’s thermal management software, and Apple is rolling out a macOS patch to fix the problem.

After many performance tests under many workloads, we have identified a missing digital key in the firmware that affects the thermal management system and could reduce clock speeds under heavy thermal loads the new MacBook Pro”… “A bug fix is included in the update macOS High Sierra 10.13.6 today and is recommended.

“We apologize to any customer who has had less than optimal performance their new systems,” added Apple. “Customers can expect the new 15-inch MacBook Pro to be 70 percent faster, and the 13-inch MacBook Pro with Touch Bar [two times] faster, as shown in the performance results our website. ”

MacOS High Sierra 10.13.6 Update is a “stability and reliability” update, recommended for all users, including 13-inch and 15-inch Touch Bar models, incorporating Intel Core 8 “Coffee Lake Technology “. I5, i7 or i9 processors. New MacBook Pro users will need to manually select and install the update from the Mac App Store.

Apple’s first performance claims for new MacBook Pro models did not seem to reflect the impact of the bug. The problem was reported by YouTube videographer Dave Lee last Tuesday and cfirmed in tests by AppleInsider.

He was initially suspected of assigning new models with a Core i9 chip, probably because this model is clocked at the highest and can be driven to a higher temperature faster. For many users, the problem did not appear at all.

Despite widespread assumptis that Apple had failed to design adequate cooling for the new generati of Intel processors, or even deliberately limited the performance of its new Pro equipment to prevent overheating, the real problem was simply a software error heavy and sustained workloads.

Without the fix, the new machines could produce worse reference results than previous models that they replaced, unless the machines were cooled from the outside beyd what the soluti designed by Apple could provide.

After installing the fix, the new machines should systematically reflect the performance specificatis originally released by Apple, which showcase the latest generati of Intel processors running much faster than the models that they have replaced. AppleInsider will ctinue to test the subject.
