Apologies as I've seen this cover before but haven't had any luck with a fix.
Using iMac 27 inch late 2013.
Trying to go from Cataline to Monterey.
Followed all the instructions:
Select model 14,2 (and tried 14,3) Create installer and load to an external hard drive Build/install OC and install onto same external hard drive Follow option to reboot, hold opt, and get to the boot screen. The only option is my original HDD.
Am I doing something wrong?
