Apple Event: May 7th at 7 am PT
I try to install an unsupported MacOS on my 2009 iMac and the installation went bad. While installing the unsupported OS, I deleted the previous operating system which was OS X el Capitan to install the unsupported OS X Catalina and the installation failed, my iMac screen is now blink. What do I do???
You start over.
Startup in macOS Recovery, Erase and Reinstall macOS El Capitan, then migrate or restore from your Time Machine backup.
