I am trying to convert my macbook pro into parallels pvm. macos Yosemite with parallels 12, guest macos Yosemite. ATM I am trying to using the same macbook pro host itself content as the guest macos using parallels 12. 1. I created the basic Yosemite pvm using parallels and configure it with two hard drives 2. I used disk utility restore function to restore the second hard drive with the content of my bootable macbook pro hard drive. I knew I could use CCC, i just prefer the apple original disk utility to do the clone job. And I did not wanna mess with the time machine, because it will not be the exact the clone copy of the original one. Obviously it will not boot, whenever I try so it will give me the white prohibition sign. when I use diskutil list to check the hard drives macbook pro hard drive: GUID-partition_scheme EFI Apple-HFS Macintosh HD cloned guest Yosemite second hard drive: GUID-partition_scheme EFI Apple-HFS Macintosh HD guest Yosemite first hard drive: GUID-partition_scheme EFI Apple_CoreStorage Apple_Boot Recovery HD would this be the reason why it will not boot? How can I make this work??
