Mac OS 9 works perfectly on my iMac 233 rev/a. Multiple Users works like a charm, Encryption and voice recognition are great, and I have even seen speed boosts to some things... (including games,
) so, in short I must say from experience troubleshooting Macs for $, that many problems with this OS are probably due to third party extensions, and I have noted that a clean install solved the VAST majority of them....
so, like I said, no problemo!!!
