Apple has released a second supplemental update for macOS High Sierra 10.13.6 for 2018 MacBook Pro models. The update is around 1.3GB in size and aims to improve stability and reliability for users with 2018 MacBook Pro with Touch Bar. Apple had released the first supplemental update in July, to address issues related to throttling of Core i9 processors, under heavy work load.
This is the second update for macOS High Sierra 10.13.6, which is only available for new MacBook Pro users. Apple did not give any details on the focus areas for this update. The release notes only say the following:
The macOS High Sierra 10.13.6 Supplemental Update 2 improves the stability and reliability of MacBook Pro with Touch Bar (2018) computers, and is recommended for all users.
This update is listed on Apple’s security updates page but the page itself is empty. It likes includes a new firmware version for the T2 chip inside the MacBook Pro.
To download the update, open Mac App Store on your MacBook, and click on the updates tab to see the new download. Alternatively, you can download the dmg file for the update from Apple’s support website and run it on your Mac to upgrade.
So far, users have reported good things about this update. Even though it is not mentioned in the release notes, users have reported that the update has fixed graphical glitches, kernel panics and speaker output distortion. It is too early to say but Apple might have included further improvements for throttling issues too.
Apple’s new 13-inch and 15-inch MacBook Pros were released with major new updates like fast Core i9 quad-core and hexa-core processors, respectively. Both models also got ‘Hey Siri’ support, thanks to a new T2 chip, and True Tone displays, similar to iOS devices. The 15-inch model can be customized with 32GB RAM and 4TB SSD.
This is likely the last update to macOS High Sierra, as macOS Mojave is in the final stages of developer and public beta testing and should be released to all users over the coming weeks. macOS Mojave will introduce new features like a system-wide Dark Mode, Desktop Stacks, updates to Finder and Preview, new apps like Stocks, Home, News and much more.
