Hi, I followed the guide just now.
Everything worked fine up until now (in fact I am currently writing this post on my new machine.)
I can boot just fine via Clover using the USB device. But when I remove the USB stick, reboot and try to boot into Mac OS from Clover it doesn't work.
Clover loads up, shows me two boot options (Mac OS and Recovery Mode), I select Mac OS (just like I do using the usb stick).
But then it loads for a while and then reboots itself and I'm back in Clover. I guess I broke something because I tried to install clover as if I'm using BIOS but later noticed that my UEFI settings had "legacy first" enabled in boot settings. I disabled that now but I guess I broke clover because of my BIOS stuff install attempt. I tried to install clover for UEFI using this video:
But this didn't work either. So where I'm standing now is: Everything seems to work, except boot without USB stick. Hope someone can help.
