When i load some applications, i get this: Classic cannot find a Mac OS 9 system folder on the startup disk to use. It further says to install Mac OS 9.1 or later (Classic Support). My PB is running on Mac OS X v 10.4.7 Does this mean i have to reinstall Mac OS 9.1? Question: Is this possible or feasible? Wanted to try out wormscanner but it needs Mac OS 9. Is there wormscanner for Mac 10.4.7?
