Installation failure
Currently I use Mojave 10.14.6 on my MBPro 15" 2018, I wanted to install Big Sur, but installation failed. The Installer quit without giving an idea why. I tried to install Catalina, also without success, same problem.
Can it be that it's because I still have iPhoto installed?
I know it's time to switch to Fotos, already migrated 70.000 pictures to a Fotos-library so I'm ready to delete iPhoto, if necessary.
Or any other idea?
Thanks in advance!
