Is there anything I need to know before running windows 10 (dual boot) with OC 0.7.4? I have it installed on an internal SSD and haven't booted it up in a very long time.

Any gotchas or things I should avoid? I'm scared I'm going to destroy the big sur side just booting into it lol.

It's always advisable to manually verify config.plist settings. With OpenCore 0.7.4 we should verify the following:

1. ACPI --> Add --> SSDT-DMAR.aml --> Checked on
2. ACPI --> Delete --> DMAR --> Checked on
3. Kernel --> CustomSMBIOSGuid --> Enabled
4. PlatformInfo --> UpdateSMBIOSMode --> Custom
5. PlatformInfo --> DataHub --> AdviseFeatures --> Enabled
6. BIOS --> VT-d --> Enabled

P.S. Always have a bootable backup of macOS.

I did not clone my working Monterey system on a sata drive back onto my internal NVME main drive.

I had a working Big Sur system running on an NVME drive. I cloned that system onto a sata SSD drive, updated the ssd to Monterey, and verified that it worked.

Once I verified that I had no bugs/ broken features, I proceeded to update my internal NVME drive as well to Monterey from Big Sur.

Both drives started with the same Big Sur installation (minus some data such as movies that were not important for my test, so those were not cloned), and both drives were independently updated to Monterey using the same installer

Some things to consider:

• In the bottom right corner of OpenCore Picker we'll see the version string. It should say REL-074-(Date). That tells us we've booted from the right EFI partition.
• At the same OpenCore Picker we can press and release CMD-V and then select our macOS boot icon. This enables Verbose mode. If the boot process freezes, we can often get some hints from the last few log lines.
• It's also a good idea to perform a cold start:
  • Shutdown the system
  • Flip power switch on PSU to OFF for 10 seconds

I will try those tonight and get back to you. I'm fairly confident the correct version of OC is used, because my previous OC version was 0.6.4 and it does not boot Monterey at all.

I think that my NVME drive somehow died.

It let it sit for ~1hr, and it ended up booting, but it had some permission errors. I tried to wipe it, but the data partition would always fail to unmount. It erased 40% of the way on the command line before throwing an error. Tried erasing it on a real Mac, but no luck. The drive is running extremely hot, even when not in use. I will try with another drive and let you know in a few days how it goes. Most likely the issue was hardware-based, and somehow upgrading the drive killed it.

So I used HackinDROM to update my install today, and it went flawlessly. Which I have to say "Wow", we certainly have come far.

While I was playing around with the system (9900k and RX580), I went in and changed the platform ID so that the system would be headless

'headless platform ID 0x3E980003'

I don't know if I see any difference or not yet.

I've got an extra 5600 XT that I was going to put into the system. (No game playing, exclusively used for development with dual monitors, YouTube video playback, a million chrome browser tabs - I don't do any video rendering or anything like that.) I was wondering if it's worth it now to change the SMBIOS to an iMacPro1,1 from IMac19,1 since the video card is going to be so much 'faster'.

I occasionally notice some slow downs when I have a million windows on the screen.

Just to double-check: Was the Platform ID entered in reverse byte order, like this: 0300983E?

It is possible to experiment with a new System Product Name, but we should proceed with some caution, like this:

• Log out of Apple ID from System Preferences --> Apple ID --> Overview. This will ensure that a new product does not get registered to your Apple ID.
• Then simply change System Product Name from iMac19,1 to iMacPro1,1 and save config.plist.
• Reboot.
• Perform as many tests/benchmarks as you like in order to determine whether iMacPro1,1 makes any difference.

Sorry for the late reply. I was traveling. I thought my GPU device properties were configured correctly. Where would you suggest I find the correct properties? The Dortana guide isn't very specific on Radeon VIIs.

If you’re using an iMacPro SMBIOS, you need to make sure your iGPU is disabled in your bios, and you have no “headless” device ID in your config.

If you’re using an iMac SMBIOS, you would need your iGPU enabled in your bios, and the correct “headless” ID in your config.

That’s it.

There is no specific device ID that I know of between cards (save for some alterations to your config settings on 5700xts and above), but those device ID entries are specific to your cpu if you are using “headless” iGPU. You DO have to remove the boot argument agdpmod=pikera for a RVII.

All details for all of this are in the setup guides of this thread, as well as the dortiana step-by-step guide.

Certainly the simplest is to use the iMacPro SMBIOS method, and I do believe there are performance benefits in editing programs by doing so.

We noticed a number of graphics glitches with Mojave, fewer with Catalina, and almost none with Big Sur and Monterey. Hence it's okay to use iGPU.

@CaseySJ I pulled the RX 6900XT from my hackintosh and switched to the iGPU. Not great, but it works. Any suggestions on Bios settings for reasonable performance?

Here's the 6900, now water cooled, in my new rig! Waiting for the new 1200W power supply to arrive. Getting closer to completion every day!

Thanks for your reply. I've done all that. No idea what I'm doing wrong. Anyway, it works fine, just the rendering is slower than with Mojave and Clover. Annoying to upgrade and lose speed.
