Monterey external boot problems. Help needed.
I have the question about making time machine restores bootable. ( Or how to make an external drive your boot disk with the files from a time machine backup). There is a thread that is closed that addresses that need but discussions are referring to older OS. Now that we are in Monterey, and both Super Duper and CC Cloner have newer versions and features I'm having a lot of trouble doing this.
I have tried a couple of things. I used Terminal for the first time and was pleasantly surprised I was able to make a Monterey boot disk doing this. But when I tried to add a TM backup to it, it wasn't bootable. I suppose each time you add the TM backup it copies it on the disk erasing what is there. I'm not sure where to turn and I will appreciate your thoughts on this.
One final note, the reason I need this is that I bought a 2020 iMac with a flash drive of only 500 MB. I didn't consider that any of my backups would need around 15 Gigabytes of space to be restored on to the HD. I have a 2 TB External Disk that I want to use as my boot disk.
Thanks in Advance, Sammy
