Hello
@Mattioo,
This might be a simple problem (let’s hope). Some questions:
- Do you have the USB install disk or a bootable backup disk?
- If so, please try booting from USB or the backup disk. Press F12 at the BIOS Splash screen and select the disk from the boot menu.
- Then Clover will appear. Choose the option to “Boot macOS from Mojave”.
- Does the screen go black? Does the system crash?
- Also, have you disabled the MSR 0xE2 register by following the Mini Guide? Disabling this register is not necessary, but if you did choose to disable it, what version of BIOS was running at the time (F6)? And what version of BIOS is running now?
So, after two days of investigation I'm not much more advanced.
For information I have the Radeon VII and my BIOS is F6. I havent done the MSR 0xE2
@CaseySJ.
During my searches I found out that OsxAptioFix2Drv-free2000 was apparently a risky memory kext to use said by his own maker, so I decided that it wont harm to upgrade everything. I'm now currently using the OsxAptioFix3Drv with the last clover 5070.
I changed the SMBIOS to iMacPro 1,1, and did the Pro Apps - Option 1.
I had problem with Quick View but this boot argument "shikigva=32 shiki-id=Mac-7BA5B2D9E42DDD94" it fixed it.
Despite I had perfect booting with this new configuration and everything was working, I still suffer from sudden black screen. No freeze before, the keyboard become not active (cant switch on the caps lock) but all the leds and fans stay on. I dont know where to look for a crash report file if there is one ?
I've been using a friend EFI folder who has almost the same build except he has a Vega 64, coming back to my previously working EFI iMac 19,1 and trying the iMac Pro 1,1 with Virtual SMC new memory kext I have the exact same behavior. I have kernel panic error sometime during boot, and when the computer boot, between 10s until 10min I will have this black screen crash.
After some test I had done I could not even boot at all because of Initial Display : PCIe 1 Slot, it was always black even with the card unwired and HDMI plugged in MoBo. I had to reset the cmos so I have a blank BIOS setup now to configure again. I wanted to connect back the discrete GPU, and I could boot again and see designare boot logo. After 20 second being in the BIOS setup I encountered the exact same issue, black screen and then my screen saying no signal.
During other tests I did, I could keep my computer on for 1h so apparently no crash and black screen if I was only connected to the MoBo HDMI and my Radeon VII unwired.
Is my Radeon VII the problem ? What happened after 1 month of using this very stable hackintosh ? The only things that changed are the apple last security update three days ago but I used my hackintosh for a full day without issue after that, and my cat dropping 1/3 of a glass water on the table during the night but I'm absolutely sure its just a coincidence as no water got anywhere else than the table. I found out the mac going nuts with the fan and screen black when I woke up in the morning. Can it be the OsxAptioFix2Drv-free2000 that finally broke something in my build as the developper say it can ? Why does it work for 10min with no issue, I can even play demanding game so the Radeon VII is still working ? Is the problem software ? Hardware ?
I'm such no expert that I'm getting out of ideas, except formatting everything and trying a clean install. But will it be really a clean install ? Is it worth to try ?
