Just wanted to say thank you
@CaseySJ for the work put into the app. I got ballsy and did a direct update from 10.14.6 to 10.15.7 on the Z390 Designare build... Used the HackinDROM app to update my existing Opencore 0.6.8 to 0.6.9 and got the intel bluetooth and wifi to work now, which was not working at all before.
Had a panic first boot, but a quick google search and I figured out there are dupes of a few things that needed deleting in the ACPI folder and a few of the wifi kexts and then it was smooth sailing. Also had to download heliport to configure wifi. Saw the wifi interface shows up as Ethernet2 in Network section but I remember reading somewhere about that.
Thanks again...
