I recently bought an iMac Late 2013 that supports up to Catalina, but with OCLP I updated it to Ventura 13.4.1, the system was installed and the patches well but then I turned it off and when I turned it back on the system load well but when the screen of the choose user when I chose a user the screen was turned off for half a second and then appeared on the screen to choose user so in an infinite loop and even the screen would turn off at times without me touching anything, I had something similar happened in a virtual machine with host in Ubuntu and had OS X 10.8 only with white screen. Does anyone know why it happens and how I solve it? ⌘🥵
