After few weeks battling with iCloud and Mountain Lion GM, it has been figured out ! See below for a fix.
1. Extract efi bios from vmware-vmx.exe by opening it with 7zip
2. Look in “.rsrc/BINRES”. extract the 6021 file, rename it to EFI64.rom.
3. Copy EFI64.rom to where the vmx file is located for the vm on the vmfs data store
4. Add line efi64.filename = “./EFI64.rom” to your vm vmx file
Thats it. Start the machine and sign in to iCloud.
