Apple Releases Second macOS High Sierra 10.13.6 Supplemental Update for MacBook Pro With Touch Bar

Apple on Tuesday issued a second supplemental update for macOS High Sierra 10.13.16 for use with the latest MacBook Pro with Touch Bar models.

The update is aimed at improving the stability and reliability of the operating system on the new laptops. Apple’s support page advises that the update is “recommended for all users” of the model.

The first Supplemental Update was released shortly after the release of the 2018 MacBook Pro range. Apple had discovered a software bug in the thermal management software that cause excessive processor throttling when under heavy loads.

The update fixed an issue that was causing the new MacBook Pro models to perform slower than the previous models when under throttling.

Recent complaints have surfaced in Apple’s support forums about an issue where a Mac crashes, goes into kernel panic, and either requires a manual reboot or restarts itself manually. Error messages related to the issue mention Bridge OS, which is an embedded operating system used by the T2 chip.

The T2 is designed to handle numerous functions on behalf of the main processor, such as boot security, encrypting and decrypting data on flash storage, and powering “Hey Siri!” prompts.

The total file size of the patch is 1.3 GB. Apple has not specified what fixes are present in the update. If we hear anything, we’ll update this article.
