copying old hard drive onto new
Installing new hard drive into MacBook Pro 15". I was told to copy the old hard drive first, then take it out and install the new one.Then after verifying all is okay, erase the old hard drive, put it in the new enclosure and use it as an external drive.
I hooked it up and the Mac said not supported and am in neutral now till I find the next step.
Is this a good question?
