Releases of Mac OS X prior to Mavericks were paid upgrades. As such, full installers mostly do not exist for these versions. Apple made exceptions for Mac OS X Lion and OS X Mountain Lion, which were released as a free download on the Apple Support website on 2 July 2021[1][2]
. On 24 October 2019 and 10 February 2015 , in preparation for an Apple Software Update certificate expiring causing installer packages to display an integrity error and refuse to install, Apple reissued many updates, signed with a new certificate.To install copies of macOS without updated certificates, change the Mac's system clock to sometime prior to 24 October 2019date 1001000019
to set the date to midnight on 1 October 2019 . Press ⌘Q to quit Terminal and return to the installer.
Most downloads are a patch updater (upgrading directly from the previous version), or combo updater (upgrading from any earlier version in the same major release). To perform a clean installation of macOS, use a full release build.
