Q. Does MacintoshManager support Mac OS X clients?

A. OS X 10.2.x clients require Mac OS X Server 10.2.x for full management. On Jaguar Server, the Mac Manager analog is called Workgroup Manager. (Take a look here: http://www.apple.com/server/workgroup.html)

If you are running 10.1.x Server, then Jaguar clients can be configured with local settings (using a combination of System Preferences > Accounts and NetInfo Manager) to provide some but not all of the functionality of Mac Manager, though it's probably not for the faint of heart.
