DOWNLOAD Download latest Install MacOS High Sierra.app from Apple store: https://it. MacOS 10.13 High Sierra is now available as a free download from the Mac App Store. Here's what you can expect to find once you install it. The Gold Master candidate was build number 17a362a. I noticed Time Machine backup sizes increased drastically on Catalina compared to previous versions. Hourly backups went up from 100mb to 1.5GB without any major changes to the filesystem on my part.

Now that macOS High Sierra has been released, it’s become more difficult to access the macOS Sierra installer in the Mac App Store (MAS) for those who still need it.
Previous versions of OS X and Mac OS X which were purchased by an Apple ID will appear in the MAS’s Purchased list for that Apple ID, but macOS Sierra is an exception because it did not need to be purchased using an Apple ID.
