Been suffering on this one, I've already read all the posts around in the forum regarding dropping MATS/BGRT, adding the fix under Clover, replacing previous AppleACPI kext... none of these haver worked so far, or maybe I am doing it wrong. I get a Kernel Panic every time.
So I'm calling you guys, maybe someone with the same/similar board has made it... or maybe someone with more knowledge than me can point me the safe path.
2 x Xeons 2650 Sandy Bridge
32 Gb Ram
MacPro 6,1 SMBIOS
10.12.6 is running smooth and flawless at the moment. I've attached my SSDT (I use SSDT + SSDT1 for PM) to the post and also my config.plist, maybe there is something to dig in there I ignore.
Made some progress, I installed from 10.12.6 using the manual method on another drive High Sierra, from there I replaced AppleACPI kext from 10.12.6 to avoid getting an immediate Kernel Panic. Now startup moves on but then hangs at a particular moment and then the screen becomes garbled.
Please not that this is booting from SATA and NOT USB...
Thank you and any help will be greatly appreciated.
