I have tried both Fedora (Gnome) 31 and 32 on both a MacBook Pro Late 2012 and a Early 2013, and the issue is the same:
The liveCDs (31&32) boot up and working just fine on both machines, but Anaconda dies before its GUI comes up. I have tried to start anaconda from the Terminal and then it fails with a message about UnicodeDecodeError. It couldn’t be some sort of architecture-issue since the liveCD boots and runs just fine, right?
I have also booted the liveCD with the Troubleshoot option which has basic graphics, same issue with that Anaconda dies before the GUI is loaded.
What puzzles me is that I used the exact same liveCD (x86) to successfully without a single issue install Fedora 31 on an Asus laptop a couple of weeks ago (loved it!)… Is there a special procedure needed for MacBooks?
Any help would be greatly appreciated - I am aiming on switching from Ubuntu to Fedora because I think the Gnome experience is purer/better on Fedora
