Setup and Use an External SSD as your Startup Disk on a Desktop Mac
I followed the instructions on this thread: How to Setup and Use an External SSD as y… - Apple Community but when I go to select the SSD drive to install macOS Monterey on it doesn't highlight it to continue.
The external SSD is formatted to what was narrated in the above thread.
Does anyone have any ideas as to what I'm doing wrong.
Thanks
