RE: your tip about finding High Sierra and other versions of the OS in Purchases section for those that previously downloaded the OS installer, that’s the best way to get any previous OS version when a new OS version comes out.Īpple always hides the prior versions from download after the new version comes out. If you know of any other tips or methods to download older versions of MacOS and Mac OS X system software from within MacOS Mojave, share them with us in the comments below!

Users who had previously downloaded other versions of macOS (including High Sierra) using the same Apple ID can also find the prior macOS releases available from the “Purchases” section of the Mac App Store.

For whatever reason, Apple has hidden the installer, and thus you must click on a direct download link that opens directly to the MacOS High Sierra download page within the App Store. Interestingly enough, if you try and search the Mac App Store for “macOS High Sierra” from within macOS Mojave, you will not find the installer in the Mac App Store listings. Another option would be to perform a macOS High Sierra clean install, though a clean install completely erases a Mac and removes all data from the computer, making it less practical for most users given that most users want to maintain their personal data. Instead, if you want to downgrade for whatever reason, your best bet would be to downgrade from macOS Mojave to High Sierra (or earlier) by using Time Machine backups made prior to the initial Mojave update. You can not install an older macOS release over a newer release. Note that this is not a downgrade process nor is it intended to be, it’s merely downloading the macOS High Sierra installer onto a Mac running the newer macOS Mojave release. Once you have the macOS High Sierra installer you can copy it elsewhere, use it for making a bootable macOS High Sierra installer, use it for installing macOS High Sierra into a virtual machine like Parallels, for setting up a dual-boot environment, or whatever else is necessary. MacOS High Sierra will download into the /Applications/ folder of the Mac, labeled as “Install macOS High Sierra”.From the Software Update preference panel, confirm that you want to download macOS High Sierra by choosing “Download”.Click here to download macOS High Sierra from the App Store from MacOS Mojave, then click the “Get” button, this will redirect to the Software Update control panel.Need the macOS High Sierra installer again but you’re running macOS Mojave?
