Thanks Donk. Yes, I'd like to try the NVRAM changes. Please let me know the instructions.
An update on iMessage Enabler:
- Before install iMessage Enabler, I got the iCloud partially working without modify anything.
- The OSX package of iMessage Enabler installed without any errors.
- Applied the script to modify the VMX configuration file, the VM crashes at boot time (The bootloader won't work).
- Restored the VMX configuration file, the booting process hangs forever at grey Apple logo.
