It would depend on the version of Mac OS X you would want to upgrade. There's no worthwhile upgrade for any system that would have run Mac OS 9, anyway.

Windows XP :-)
No Mac OS version can be considered to be in the direct upgrade path, as Mac OS runs only on Macs, and is incompatible with all of the software of Windows 2000.
