Hi gaucho,
Do you use DSDT and/or SSDT in clover?
Can you post your config.plist file for clover?
I did not use DSDT/SSDT. I made a USB Clover boot (r2976) disk, and got the system booting with that.
Then I used info from post 4409 in
this thread to configure the EFI. messing with the serial numbers/MLB/ROM etc was info drawn from the Tonymac thread on the subject, and this ****** post .
Since I did not run iMessage debug, I had to start from scratch. I chose a 13,1 configuration, made sure I had a clean serial number (checked on Apple website), and used serial+5 characters for MLB.
The Clover installer was as minimal as I could make it. The only kexts I have are the AppleIntele1000e.kext, Fake SMC, and NullCpuPowerManagement.kext.
To transition from the USB, I used the same Clover installer, only selecting UEFI this time, and then copied my EFI folder from the USB to desktop and then mounted the EFI and replaced the EFI folder there with the one on the desktop. (I found that tip here on TM).

the attached config.plist I removed the serial numbers from.
it boots quickly, network, sound, iMessage, iCloud, everything works as it should. I did have to call Apple, they did ask for my serial #, but I told them I was at work and only had the "call apple customer code" with me. Took about 2 minutes. they were very helpful. I swear my display is sharper booting from Clover instead of Chamelion, but that's probably just me.
Using the USB Clover boot disk was the best idea I had heard. Always had Chameleon ready to bail me out. I guarantee I have a complete iMessage debug data dump safely stored away now.
edit: I have since added TRIM to my config.plist (with no problems).
