Question: Super Duper: cannot find the bootable drive upon startup

I have been using Super Duper for many years. Recently, when I try to use a bootable close upon startup, my iMac does not find any bootable clones. They reside on a Thunderbolt drive connected directly to my IMac. I have recently upgraded to High Sierra. So I made a clean bootable clone, erase drive then copy. Stilll when I do a restart, Hold the "Option" key upon restart, no bootable drives are found. any suggestions?

iMac (Retina 4K, 21.5-inch, Late 2015), macOS High Sierra (10.13.1)

Yes. Time Machine creates a bootable Recovery Partition on the TM backup disk. Booting from it (using Startup Manager) results in the same macOS Utilities screen as booting any other startup volume’s RP, or Internet Recovery.

Other than the firmware password, that's all I can think of. I could ask when and under which macOS version those Time Machine backups were created but it's probably not worth pursuing. If they don't appear it won't help.


If external drives are not being recognized at all, an SMC Reset has been known to fix that: How to reset the System Management Controller (SMC) on your Mac - Apple Support. Try it.


From How to use Time Machine to back up or restore your Mac - Apple Support:


In OS X Lion v10.7.3 or later, you can start up from your Time Machine disk, if necessary. Hold down the Option key as your Mac starts up. When you see the Startup Manager screen, choose “EFI Boot” as the startup disk.


However, mine are appearing with the name of the drive e.g. "Backup01" etc. I haven't seen "EFI Boot" for a while. Perhaps that changed in HS.

I think I found the issue.


I plugged the lighting cable into my iMac keyboard. Restarted and everything works as it should, TM and Super Duper appear as bootable options.


So the problem must be in the iMac recognizing the wireless keyboard upon startup. It could not see the 'option' key depressed before I attached the lightning cable.
