If you have a robust enough Mac.. eg. at least 20% more RAM than was shipped with it, and the latest version Mac OS you can use one of two most popular Windows Emulators (which are really just dual boot systems) and run EQ2. It's not guaranteed to work, especially on Mac notebooks. However, I know a few people who have no problems running EQ2 this way. The draw back is that you need to run the performance at best at Balanced mode. Because, regardless if its a dual boot emulator or not.. the Mac OS is still running in the background.
The second option is to do what 90% of other Mac users have done and boot up the old PC and accept that one must decide between running a Mac only home/business or diverse computer environment. ;)
