Just for fun (and in the event I switch from Mojave if needed only, ie, not now!), I’ve created an EFI bootable OC 7.1 as a test. BTW, thanks
@CaseySJ as the work I had to do was minimal as you already did it for us!
Result:
- flawless except a few things I had to correct regarding Windows 10: no way to insert some patches, mainly PEGP to GFX0 (instant BSOD) because WhateverGreen is a no go for me, instant iTunes crash!
The solution I found about WG and iTunes crashing, « shikigva=32 shiki-id=Mac-7BA5B2D9E42DDD94 », is counterintuitive as I’m already running with iMacPro 1,1??
Anyways, I don’t see any difference with the RX560 located at PEGP or GFX0 performance wise.
- no need to enter the CPU frequency (anyway, it couldn’t be done if I’m not mistaken). In Clover, it’s mandatory for Native Instruments (Native Access) to work properly.
- all softs (audio plugins, etc…) authorized without a hitch as I transferred carefully the important bits from Clover (serial, etc…). iMessage and al too…
- I customized (removed or added) some kext or SSDT’s and it was a breeze with OC Configurator.
I’ve gone back to my trusty Clover 5099 as there is a rule with an Audio Workstation: « if ain’t broken, don’t fix it ».
However, I now have the latitude to move forward in the case I ever need it.
Thanks for this wonderful thread, it makes it easy!
