On Tuesday, Apple released the macOS High Sierra 10.13.6 Supplemental Update that is supposed to fix the CPU throttling issues that have plagued the 2018 MacBook Pro since its release. We installed the update on a 15-inch 2.9GHz Core i9 MacBook Pro, and ran several benchmark tests to see if, as Apple promised, performance improved.
Our preliminary results show that yes, the update does boost the laptop’s speed. For example, in our Adobe Premiere test, the updated 2018 MacBook Pro was about 11 percent faster than the same laptop without the update. Compared to the 2017 15-inch 2.9GHz MacBook Pro, the updated 2018 laptop was 22 percent faster.
