Hi thanks for your reply.Assuming you kept everything else the same, changing "Firmware Features" and "Firmware Features Mask" should have no affect on Messages, FaceTime, or Handoff.
If Preview and Quick Look was working and suddenly broke one day, even before changing Firmware Features and Firmware Features Mask, your problems probably lie elsewhere.
Everything worked except waking the screen and that happened from one day to another. I just restarted the machine every day. But that could not have been the solution for ever.
So that is why I switched to iMac Pro 1,1 but of course to keep the Preview / Quicklook alive I had to turn off the igpu. And I just kept everything the same. Probably that is the problem. But also after changing the SN and Board Serial and also the UUID did not bring iMessages, Handoff, etc. back to life.
What do you use? iMac Pro or the normal iMac? Could you share your config.plist / SMBIOS from clover? Or do you have anything else to consider?
Hi, also thanks for answering.I had a similar issue on my iHacPro. what you are describing seems to be UUID issue. Make sure clover converts your custom uuid, and if switching smbios, you should change UUID as well. I don't think the same uuid would work across different smbios
Tried everything. Erased the whole partition except the EFI. Generated a new SMBIOS, Installed Catalina, everything except the Messages, Handoff etc. works. Drives me crazy.
Is there something important in the nvram.plist that I have to change too?
Maybe I should try to use the iMac 19.1 again. Worked good till the issue happened. But I also read that it would be better to stick with iMac Pro 1.1 because that would have better results with rendering out videos and other pro apps like adobe stuff.
