[Solved] Mac OS Installer on Thumb Drive
Hi all, and Happy New Year
I keep a Mac OS (Mojave) installer handy on a thumb drive. Simple and quick question: Should I periodically update the thumb drive by downloading the current installer from the App Store and recreating the thumb drive installer after every major update? Or, is it better to just keep it as it is, install with what's there, and then update the newly installed OS on the machine in question? My gut feeling is I'd rather have the latest and greatest on the installer thumb drive, but maybe updating it periodically is overkill. What say you?

I think keeping the thumb drive updated is overkill.
Only create a new installer thumb drive once a year, when there is a new major macOS release.
At that time, if you are staying with Mojave and not going for the latest and greatest (or you have older machines you have not upgraded yet), then maybe upgrade the Mojave thumb drive to the latest release (or maybe do it a few days before).
On my flash drive, I installed macOS for cases where I need to boot a nonworking Mac. I also keep various versions of macOS installers on the drive depending on the destination Mac model and user need.
I boot to the flash drive, copy the installer to the destination drive, and run it.
