Hi Dev1984,
You can install Symantec Encryption Desktop on MAC and encrypt the drive, which will report to the server and can be managed from there, below is the article for the supported SED versions for corresponding MAC version:

About managing/monitoring MAC encrypted with File Vault with Symantec Server that can be done with Symantec Endpoint Encryption, another encryption solution from Symantec, which is also covered under the same license key.
This adds management of FileVault2, the native encryption solution from Apple. Management of FileVault2 includes two major components: client and server. The client is installed on a managed Mac OS X system, and the server is part of the Symantec Endpoint Encryption Management Server. Key recovery and reporting will be supported through the Symantec Endpoint Encryption Management Server.
