How To Mount A Hard Drive Mac

You might be able to call Apple and order a set of the original gray system discs. Last time I did this they were $16 each and I believe there are two of them. The retail disc is an earlier version of Snow Leopard (10.6.0) than was shipped with your Mac (10.6.3 or 10.6.4). The retail disc won't work because your Mac won't run an earlier version of the OS than it originally shipped with. So the problem is not with your computer but with the disc you are trying to use. In all likelihood the computer itself is fine.

Connect the FireWire or Thunderbolt cable to the corresponding port of the target computer, and then connect the other end of the cable to the host computer's port.
• In System Preferences, from the View menu, select Startup Disk. In the Startup Disk preference pane, click Target Disk Mode. To exit Target Disk Mode, on the host computer, eject the target computer's disk, and then shut down the target computer. Disconnect the cable, and then start up the target computer; it will boot normally.

Reading PC-formatted hard drives using your Mac is easy enough. Just plug in the drive, then access the files you need to use. But writing to that drive? Well, that's a little more complicated. This is due to the fact that NTFS, the file system utilized by Windows PCs, has limited support on Mac.

Alternatively, you might be able to visit an Apple Store and see if they could install Sierra for you since your Mac will run it.

Good luck!
