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.[1][2]
To install copies of macOS without updated certificates, change the Mac's system clock to sometime prior to 24 October 2019 before attempting installation, and reset it to the current date afterwards. If the Mac doesn't have an existing operating system installation, this may be done from the installation environment by clicking Utilities → Terminal, then entering date 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.
