CAN I HAVE AN EFI PLEASE?

Google is your friend, don't ignore them.

This problem has resolved after making a new OC 0.7.6 Monterey EFI. Still not sure of the cause.

I did install with 0.7.7 on OptiPlex 3020. Mouse stutters at first 30s. Did anybody figure this out why? After that system runs perfect.

I think that it is most likely a graphics problem. It can be fixed in the DeviceProperties -> Add section of your config.plist. PciRoot(0x0)/Pci(0x2,0x0)

A simpler solution might be to revert to an older WEG kext. Not sure how old, you'd have to test some to find out.

I have PciRoot(0x0)/Pci(0x2,0x0) in config.plist as I'm on i5-4570. What line in that section should be changed you think? I have running monterey on 7020 without any problems. I'll try section from there. I'll post results. Right now I'm running PciRoot(0x0)/Pci(0x2,0x0) from my 3020 with Big Sur. Weg kext is proper version for 0.7.7

Depends on what you have there right now. You can post it for review if you'd like.

You can try adding these framebuffer patches (in blue). Test with a USB first and remember to reset NVRAM before testing. That way you can leave the existing config.plist as is and go back to it.

Note that the last block of digits for con0-alldata and con1-alldata should be 00000000 instead of 10000000 if you use DP/HDMI audio on your 3020.

This is my 3020 with PciRoot(0x0)/Pci(0x2,0x0) changed to one from my perfectly running 7020. It will not even boot.

I'll try your suggestions this evening. Thank you.
