I recently installed macOS on my new Z390 Designare MB using your guide. The installation almost works but there seems to be something wrong with Clover itself.
1.) The "Mac OS Recovery" icon is not shown at first attempt. It appears if I push the left and right keys a few times and the smaller icons in the second row appear mis-fitted. Changing the theme does not solve this. When Clover is loaded after a reboot, everything appears well but not after turning on the PC.
2.) I have an external Focusrite Scarlett 18i20 USB audio device. If the audio device is turned off before booting, the system starts as usual. If it is still turned on, only a black screen appears after choosing macOS in clover. No text output, no kernel panic and no other error information. It makes no difference if the device is plugged into another USB port. Booting other operating systems with the device turned on is no problem.
Has anybody an idea if these issues could be caused by wrong BIOS settings or incompatible EFI files in drivers64UEFI?
