I've just installed Classic OS9 on my Mac and apparently it is "unable to update its files in "System Folder"". I was able to install OS9 with no problems on another one of my Macs that isn't running the latest version of Mac OSX and it was able to work. Can anyone tell me what the problem is here. I suspect it's either 10.4.6 or a DivX Fusion codec (I remember reading something about that on here). Thanks
