Catalina software update
I did the 10.15.7 Catalina software update on my MacBook Pro and it’s being weird. It went to the black update screen with the Apple logo and a 29-minute timer, then after about 30-seconds, the computer rebooted itself several times. Then it started the countdown over again. It seemed to work fine after that. But then it got stuck on the last part at “less than a minute remaining.” I waited for nearly 5 minutes and then tried to boot up in safe mode but it wouldn’t work. It just booted up in what looked like my old Mojave screen. So I logged in and tried to see what would happen, and it restarted the entire Catalina software update. So now it’s back to that again. Can anyone advise on what might be happening or what to do?
MacBook Pro 13″, macOS 10.7
