install/run on osx 10.5?

Welcome to the forums DaDak. Unfortunately 10.5 killed Classic, so unless you downgrade to Tiger, you can't run any classic applications.

DaDak, welcome to Apple Discussions.

You can't run classic under Leopard 10.5. You can under Tiger 10.4 or Panther 10.3. Also, you can't run classic on an Intel Mac.

One easy way to install "classic" OS 9.2.x is to copy the System Folder on a Mac running OS 9.2.1 or 9.2.2 (best) & transfer the file folder to the OS X hard drive.

Since all Mac Minis were released after Apple's shift away from Mac OS 9 booting and restore CDs that included Mac OS 9 on their label, restoring Mac OS 9 on a mini requires these instructions from the original Mac Mini installer discs that came with your Mac Mini G4:

or these instructions:

If you are missing those discs, you may be able to get ahold from AppleCare of replacements. If they don't have them, and you didn't get those discs when purchasing your computer, contact the original owner of the machine to see if they still have them.

You can either erase and partition your hard drive to have 10.4.11 and earlier on one partition following these directions:

or you can connect a Firewire external hard drive known to be compatible with 10.5 to restore your Mac OS 9 system folder. If you made a backup before installing Mac OS X 10.5, you can always restore your backup.

Good luck. By the way, check my FAQ on migrating to Mac OS X*:

Maybe it will make the necessity of those applications no more.

Welcome to the forums, DaDak.
Although Mac OS X 10.5 dropped support for the OS 9 classic environment, it appears that you can still install it seperately onto your Mac Mini. This is the list of hardware that supports OS 9: http://support.apple.com/kb/HT1835 As far as I can tell, all machines that have PowerPC processors can run classic. You'd need an emulator for Intel of course.

Hadye is right you need a emulator to run classic u can't boot in to mac os 9 but u can run mac os x 10.5 and mac os 9 at the same time

Macintosh os x 10.2.8

u can run mac os x 10.5 and mac os 9 at the same time u can run mac os x 10.5 and mac os 9 at the same time

Actually you can't. Read my aforementioned FAQ*:

http://www.macmaps.com/macosxnative.html#CLASSIC

They can be installed on the same system, but you still have to dual-boot 10.4.11 & earlier on a PowerPC Mac and 10.5. Intel Macs offer no legal choice for using Mac OS 9.
