me too...and only on 10.15.4 - and when it goes over HDMI.
in any other variants it works. if not 10.15.4
I have no idea why. I have the same case with Clover. Boot loader is not the cause of the problem. This is something with kexts - the kernel version and macOS itself

</dict>Changed the priority to the port - external gpu disabled, hotplug reboot fix enabled, HDMI infinite loop fix enabled...
I have enabled HDMI 2.0 - i connected 4K TV and works.
But all that works perfectly only with full UEFI in BIOS.
Otherwise it does nothing but reboot itself.

I'm trying this folder as EFI for the Z50-70. The system boots and works well (enabling legacy in the bios) but opening chrome or any microsoft apps I have glitches on the internal display. I'm restricted with apple only apps to avoid glitches. This is a problem I had from May when I sadly had to format the hack, previously I was using clover and I had no problem but with the reinstall clover stopped to work well and I don't know why.
I tried also to modify the config to boot every time in verbose (adding "-v" in boot-args) but, even if the change is recorded in the file, the system still boots not in verbose.
Sincerely I'm loosing the hope to make the system work again in Catalina, I'm tempted to go back to Mojave even if I don't want to.

Hi guys,
I got a recent problem but I don't know where it comes from and I was afraid it might be a hardware issue but here it is :
I've been stuck for a while, like one time out of two, on the apple logo after some reboot or just turning on the computer. Once I tried on verbose, It showed nothing other than the black screen and half a ligne of ++++ and nothing else happen unless I shut it down... I'm running El Capitan and using DW1830 card.
I've benn looking over the web, tried multiple time machine versin of my working OS but no changes... I really thought I had a problem with my hardware when it didn't want to boot anymore untill yesterday, I donno why but I tried and manage to boot.
Here is my debug report + attached files :
Thanks a lot for your help !
