Try compressing (zipping) your EFI before uploading.

Are you certain that the config.plist you attached is on your boot volume and is the one that OC is loading? The 'bootprotect at 5 index' error you posted would occur if you still had bootprotect in your config.plist's Misc>Security block (which would have been in a config.plist prior to OC 0.6.6).

@henryrym - I suspect that the config.plist you uploaded is not your current config.plist. The config.plist you uploaded still includes "No-hda-gfx" in DeviceProperties (the property you said you removed when trying to get sound to work). Just upload your complete EFI (with sanitized PlatformInfo>Generic>MLB,SystemSerialNumber,SystemUUID) and we can take a look.
Ok now compressed my EFI and attached - the config file in previous post was your original unedited one as I had mucked about with mine and got nowhere, thought it might not worth be unravelling.

I've reset the NVRAM and done a fresh install, deleted the 'no-hda-gfx' line - again no sound through DP - my system as per previous post other than this is a fresh install on to an SSD - output through DP on mini to DP on monitor, no adapters on cabling.

I'm 73 and want to get to grips with hacks, more comfortable with Clover but hope to pick OC up with time. Have built many pc's but only a few hacks in the past.

I'm wanting this machine to do photo editing (approx 40K family pictures) with Photoshop and Lightroom. Can do in Windows, but whole family uses MBooks, iPad & iPhones so all comfortable to use Mac OS, especially Big Sur. Have been using a Haswell iMac, but it has a cracked screen, works but iffy, so the Mini would be a replacement for when the iMac gives up the ghost. An M1 mini might suit, but doesn't have the RAM and storage we need.

Hope you can help

@henryrym - I'm going to be busy for a few days. Fortunately, there are others contributing to this thread who are very capable and able to help you.

@henryrym - I had a free minute and can give some feedback. I don't want to do this for you, because I'd be doing you a disservice (and you want to learn and be able to maintain your hack). You should review these three threads for UHD 630 Framebuffer patching:

Here are a few hints:
  • The connector types in the EFI I posted are specific to my system (DigitalDVI). Review all Known Issues (including Catalina Issues) to learn about this and other potential differences between your system and mine.
  • Your DP ports are identifed by type 0x0400, reverse byte order <00 04 00 00> (where my DigitalDVI connections are type 0x004, reverse byte order <04 00 00 00>). Learn about reverse byte order in my "My framebuffer patching experience" post linked above.
  • Your VGA port is identified by connector-type 0x0010, reverse byte order <10 00 00 00>
  • @rafale77 's Graphics Device Properties in his EFI here are closer to yours than are mine in my posted EFI. Look at his config.plist to see how he patched for 3 DP ports. You may find that you need to change your AAPL,ig-platform-id to 0x3E9B0007 (reverse byte order <07009B3E>) for working sound over DP.

I bit the bullet and applied the 11.2.1 update .... so far so good. Your mileage may vary!

Updated my HackMini8,1 from BS 11.2 to BS 11.2.1 with almost no issues. After the first reboot, OC 0.6.6 correctly selected the 'Macintosh HD' volume. After the second reboot, OC correctly selected the primary BS volume. After the 3rd reboot, OC correctly selected the primary BS volume, but a 4th reboot occurred (with a shutdown error). However, after the 4th reboot, BS was completely upgraded to 11.2.1.

Usually caused by incorrect SMBIOS in config.plist. Hard to tell without your problem reporting files (and even then, it might be hard to tell). Are you sure you generated valid SMBIOS when you installed BS? Did you use GenSMBIOS?

Are you using any sensor kexts with VirtualSMC? If so, do you mind posting them along with the name of the sensor app and a screenshot of the sensor app display? I'd like to test VirtualSMC again, but I didn't like the sensor app that I chose the first time I tested.
