A:Answer Dear Valued Seagate Customer,
This reply is from Seagate Support. We would like to respond to your question about the compatibility of our Barracuda drive with your iMac.
Generally speaking a drive will be compatible, provided the system it will be installed in has the matching interface connector. According to the information on Apple's website the drive should be compatible:

However, your system manufacturer has access to compatibility charts to verify that the model will work, so please contact Apple directly as well:
