I have an new mac book pro. I have taken the hard drive out of my old mac and placed it into an external enclosure. The new mac reacts to the old hard drive claim it cannot read it, disk utility see it as /dev/disk1s1, but first aid has no buttons active, I cannot verify it or repair it. I think that because the partition map scheme is "Master Boot Record" it is impossible for the new mac to see it! Can anyone suggest how to either use this disk like a normal external or possibly boot the new mac from the external hard drive>>>???
