macOS High Sierra 10.13 Supplemental Update Fixes Early Bugs

by Adam C. Engst

We always recommend delaying major macOS upgrades until Apple has had a chance to fix early bugs. The company has taken its first swing at the most egregious problems in macOS 10.13 High Sierra, not with the 10.13.1 update that we had expected, but with the “macOS High Sierra 10.13 Supplemental Update.” It’s highly focused, providing fixes for five specific problems:

macOS High Sierra 10.13 Supplemental Update was 915 MB on my Retina iMac, and you can get it in the Updates screen of the App Store app.

Apple says that it has already built these fixes into new downloads of High Sierra, so if you haven’t yet updated, you won’t need the macOS High Sierra 10.13 Supplemental Update when you do. But if you have already upgraded to High Sierra, we recommend installing this one sooner rather than later.
