Unable to update from Mac OS Catalina 10.15.7 on a MacBook Pro.
I have a MacBook Pro with OS Catalina 10.15.7 and have been unable to update it past this. I have tried searching through the threads here and have been unable to find anything helpful. I have tried searching software update, looking in the App Store (Will not let me download most current system/not even attempt). Has anyone else dealt with this?
