Thank you very much for that. My Z97M-D3H iGPU system was still back on ElCapitan, and I thought that I would be looking at a steep learning curve, but your EFI just worked fine to clean install 10.15. (I did have to replace the ethernet kext with one for the RTL8111 to get connectivity).

Glad to know it helped Remember to change serial number and board id for working imessage and not conflitch with other hacks

Overall the system seems to be running great; however, I am experiencing some random reboots. Haven't had a chance to do any troubleshooting.

you can try add/remove some clover dsdt patch and remove ssdts in EFI to troubleshoot(keep LPCB9 for native powermanagement and EC), some ssdts is different for different boards.
