From personal experience I can certify… - not all clone utilities or techniques clone the Recovery Drive. The only one I have personally tested that successfully cloned the Recovery Drive was Carbon Copy Cloner. ðŸ‘There may be others but either I have not tested them or they did not when I last tested them.
- the one time I attempted to install from a Recovery Drive when the Recovery Drive and the installed boot volume did not match, I had to erase the boot volume, use the RD to reinstall the previous OS X version, restore everything else from the Time Machine backup.ðŸ˜
- beta installers do NOT update the Recovery Drive (which is good in case you have to revert) 👈
- upGRADE installers create or upgrade the Recovery Drive
- upDATE installers seldom, if ever, update the Recovery Drive
If we knew what it was we were doing, it wouldn't be called research, would it?
