Creating a backup disk from a wiped hard drive
I have a new MacBook Air running OS Monterey 12.6. I have wiped all data from my old Mac Mini hard drive and am trying to use the Mini as my external backup disk. Can you tell me how to establish a matching OS (12.6) on this empty disk? I have connected it to my MB Air and mounted it, but it has absolutely nothing on it since I did a multi-wipe using Disk Utility with many passes.
Thanks in advance for your advice!
