Chosen Solution
I’m trying to put a different hard drive into a MacBook Unibody that a friend handed down to me (the silver one), but whenever I try and boot up the MacBook off the hard drive, I get a prohibitory symbol. The hard drive I’m using is a Crucial 2.5 inch SSD BX100. It was installed in a different MacBook (white unibody, 2009). That 2009 white MacBook is no longer working, so I thought it would be a simple matter of taking the SSD out of the white MacBook and popping it into the silver one. This didn’t work. I still have the original hard drive that came with the white MacBook, and the silver MacBook will boot up off of that original HD. But I want to install my SSD because it’s what I’ve been using for the last five years. What do I need to do to get my SSD to work in the silver MacBook? TIA.
ok so a few things, do you have your OS installed on the SSD? Also why did the white one stop working? what was wrong with that? Because the SSD could have been the issue on the white one. Update (10/06/2020) alright so i can suggest two things, first try to install a fresh copy of the os you plan on using, and try that. If that doesnt work if you can get a drive reader. like this photo provided for example and download a program called crystal disk and run a scan on the drive and see if their are any errors on the drive,
