Editor’s note: This how-to uses the High Sierra Public Beta software. It will be updated when the final version is released.
When macOS High Sierra gets released later this fall, Apple will distribute it through the App Store. You need an internet connection, and the download will be about 6GB, so it’ll take a few minutes.
For a single Mac, this process works well, but if you have several Macs, it’s not efficient. That’s why I like to create a bootable installation drive. I can use the drive on each Mac I need to upgrade, saving me from the process of entering an Apple ID and password and then waiting for the download.
