Apple on Tuesday released a supplemental update for users of the 2018 MacBook Pro. This is the second macOS 10.13.6 High Sierra supplemental update for this particular laptop. The first supplemental update was released in July to address throttling issues that affected performance.
Apple’s release notes only state that the update “improves the stability and reliability of MacBook Pro with Touch Bar.”
According to a MacRumors report on Wednesday, Apple said the macOS High Sierra 10.13.6 Supplemental Update 2 includes fixes for laptops that produce crackling noise through the speakers, and kernel panics linked to an issue with the MacBook Pro’s T2 chip.
Before installing the update, users should perform a back of the laptop. Once that is complete, you can get the update through the App Store. You can also download the update by visiting Apple’s macOS High Sierra 10.13.6 Supplemental Update 2 support page and then click on the Download button.
