my 2020 Imac isn't installing the new macOS update
So i'm trying to update my MacOs on my 2020 iMac. It's currently on MacOS Catalina and I'm trying to Upgrade it to Ventura. The update has downloaded but won't install on the iMac.
When I try installing it, the computer just restarts and takes me back to the desktop with no update installed.
iMac 27″, macOS 10.15
