I’m trying to boot a fedora 32 live on my Macbook Pro (15-inch, 2019). I’ve disabled the security settings and I can choose the USB at the startup. Than I’m presented with Fedora menu with 3 options. After selecting the first one the screen displays some information which seems ok and than it’s switching apparently into the graphic mode and goes dark. It hangs on the dark screen.
I’ve also tried the boot via troubleshooting but it also hangs.
This may be an issue with the 2019 MBP and the graphics card/driver on the F32 live image. Maybe you could try an F31 live image.
I don’t work with macbooks, but maybe someone here has hints related to the newer versions and the video cards they use. It really sounds like the proper video driver is not getting loaded, and since we know apple wants to keep their hardware proprietary it really does not surprise me.
