A:Answer Dear Murray,
This reply is from Seagate Support. We noticed your inquiry and wanted provide information about our Barracuda drive to you.
While our Seagate Barracuda 3TB drive will work with most computers that support SATA 3gb/s connections, it would be best to contact Apple directly to verify that this drive will be compatible with your specific system as we would not have that information here.

If you have any remaining questions or concerns, we would be happy to help using any of the support services we provide. Here is a web address with contact information should you wish to speak with a support representative directly:
