No iMac G3 models can run versions of Mac OS X beyond 10.4 Tiger.

Complete specs on the iMac G3 models, including maximum supported operating system, may be useful as well:

Hope this helps!

I don't recall Leopard supporting G3 processors. In fact, it specifically says G4 or Intel processors only on the requirements page.

Did you try looking up the minimum system requirements? It requires an 867mhz G4 or better, so no, you can't install it.

macs are for losers.

use windows like everyone else.
