As someone who owns the full, registered version of ARDI, a Mac OS emulator, I was pretty surprised when rumors started popping up that this was able to run the recently released Mac Q3Test. To clarify: it will not run! ARDI doesn't emulate a PowerPC, which is required for the file to run (this includes the recently released ARDI 2.0.) Coincidentally, the ARDI page was recently updated to clarify this:

An incorrect rumor on the net listed Executor as running Q3Test, the test-version of Quake 3 that was made available for the Macintosh before Linux and Windows. Our site has been swamped as people try to download our demo to test this. Q3Test requires a PowerPC, and Executor does not currently run any Mac applications that require a PowerPC.
