Clover and I are in a love hate battle. I have three systems that I just converted from Chameleon to Clover. The first two had UEFI capabilities and were a breeze to change over, but the X58 system is frustrating me. My main problem is a ROM of all zeros:
4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14:ROM: <00000000 00000000 00000000 00>
I'm using the MacPro3,1 definition (though I tried MacPro4,1 and iMac 10,1 to no avail). The appropriate Serial Number, SmUUID (generated with uuidgen) and a MLB and ROM are set within Clover. All values with the exception of the ROM are shown in imessage_debug to be just as set. I don't want to call Apple until all three machines have consistent values and I suspect that the ROM of 0's is not going to work even though it is consistent as zeros.
The second problem is my GTX770 cards and a Cinema Display using DP and the Clover boot. All had been been working well with a Chameleon/MultiBeast boot, but now even though the graphics cards are being recognized the monitor is not and I get a black screen upon boot. I can only see the desktop through screen sharing from another machine. I've swapped in my old ATI 6870 card for now which works fine with the display under Clover.
Planned steps and thoughts:
I'm still running BIOS FF on the GA-X58A-UD3R mb, so I'm planning to upgrade to the newest (FH), but I don't hold out much hope for that fixing anything. I'm also considering just scraping the X58 board and upgrading to one with UEFI, but I'd like to forgo the expense of that if possible, for the current system is adequate for my needs if only iMessage and FaceTime would work.
UPDATE:
Amazingly the BIOS update to FH ( or perhaps the resetting to "optimal settings" and reconfiguring) resolved the 0's in the ROM value. The imessage_debug now displays the value set by Clover. It is too late to do much more, but tomorrow I shall swap in one of the GTX770 cards to see if I can get it to output to display port. Regardless it looks like I'm ready to call Apple with the customer code to get iMessage working again.
