Running OS Monterey from an external disk
I have installed Monterey via a boot disk on an external disk and can start up my iMac 27” with it. However, the internal drive of the computer, that has Ventura installed on it, doesn’t show up on the desktop. The whole idea was to run it with Monterey again and use applications that now don’t work with Ventura anymore. Is there a way to have the built-in hard drive to appear on the desktop so all programs and documents on it are accessible?
iMac 27″, macOS 12.6
