[QUOTE="MacInWin, post: 1813428, member: 396914"] krs, I think what Rod was saying was that we here give advice to visitors that even if they don't install the version, they should download the installer, "just in case." When they do that, they have a file that can be stored somewhere as an emergency tool. Now you COULD make a bootable installer for each of those, keeping the installer on a separate USB stick for each of the versions, but what I would do is just keep the installer app somewhere and if/when I needed it, I could create a bootable installer using DiskmakerX for that version. As for Rod's last sentence, I'm a bit confused about that, too. I'm not sure what the "it too has been updated" actually means. If you have an installer that boots, you should always be able to install it, even if that means wiping out the partitions to get rid of APFS, repartitioning to HFS+ and reformatting the drive totally. Once that is installed, you can update and upgrade right through the sequence. I did that just yesterday as a test, as I said. [/QUOTE]
