I have both OSX 10.4.5 and OS9.2 on my Mac G4.
I use OS9 Classic to run older apps. that only run on system 9.
A case in point: Adobe Photoshop V6.
Until I upgrade to Photoshop CS2, I run OS9.
You mentioned that you have apps. that are system 9. Which ones?
A good reason to keep OS9 presently.
You can just switch seamlessly between 9 and 10. No problem at all.
I will wait for Pete to fully explain it and add more info for you.
Do not trash OS9 until Peter explains it to you.
I am using OS 10.4.5 (Tiger). I have no need for OS9, however I have two folders in Macintosh HD named 1.) System folder from old mac (with a logo 9 on it) and 2.) Applications Mac OS 9.
Is there a safe way to remove them, as they are just taking up space now...? Or does OSX use any of the system files contained in those folders? Any help would be appreciated.
