Hi,

I removed my GPU and put in an old GPU I had, this then allowed me to boot into safe mode where I took of the EFI string, then I put back in my GPU and it worked perfectly. I then readded the EFI string for the ethernet device to the extra/ boot.plist file and I can now login in smoothly again

Thank you very much for your guide. Fortunately thanks to following another guide online my ethernet device was "en0" and "IOBuiltIn is also showing as true.

iMessage used to work for me perfectly for the past 4-5 months, the only thing I changed was that I added a new network printer in my House and I may have clicked something in the "sharing" preferences - Like share DVD drive or something - Needless to say I have unchecked those but I still get the same "server encountered an error processing registration" - I have tried my other Apple ID there as well but I get the same message.

Any more ideas?
