Before the arrival of macOS Mojave in 2018, installers for older versions of macOS could be searched for or found from the ‘Purchases’ tab (even if you didn’t have to pay anything for them).

However, when Apple introduced Mojave, it made changes to the Mac App Store and that is no longer the case. Luckily, with the links you’ll find in the previous sections, you still have access to those download pages from the Mac App Store.

If you have access to a Mac with an earlier version of macOS, log into the Mac App Store with your password and download the Mojave installer on your Mac.

The version of Mac OS X you are looking for may never have been available on the Mac App Store. This is the case with Snow Leopard, the first version of Mac OS X that arrived at the same time as the App Store.
