Hi
I believe the root cause is due to the current Centrify version that is installed on the Mac is 5.3.0 and it does not support OS X 10.12.x When the Deployment Manager tries to run the adcheck with 5.3.0, it will fail with the unsupported version error.
This situation will occur when end users upgrade the OS before upgrading the agent. As we always suggest customers to upgrade the the agent first before upgrade the OS to avoid this kind of incident from occuring.
Can you check if the issue only occur on Mac with 5.3.0, if they are please consider to perform a manually upgrade on the Mac to either at least versoin 5.3.3 or 5.4.0 and above directly in order for Deployment Manager to work.
Please keep us posted with the result and update. Thank you!
Best regards,
Ivan
