Any tips on doing a clean install of MacOS and getting hold of either Mojave (to boot from USB) or earlier version?
@voidspace Is this of any help to you? https://scriptingosx.com/2019/10/download-a-full-install-macos-app-with-softwareupdate-in-catalina/
Thanks. I didn't want to upgrade to Catalina, just fresh install Mojave.
Ah. Looks like you can specify version. :)
@voidspace There is a minimal rescue mode accessible at boot time, which you can use to (re)run the installer. This requires Internet access.
Not sure if physical media is still available.
@voidspace if your apple ID has downloaded previous versions of macOS, they should still be available in the Mac App Store under the purchases tab. There are actually 2-3 different recovery modes that will do different installers. One version will reinstall the current OS, and another will install the OS the machine shipped with. I believe you need an internet connection either way. The different recovery modes are cmd + R and another key combo, like shift, ctrl and/or alt.
Thanks. Looks like they've discontinued that option. No version of OS showing under "purchases".
