I can't think of any problems you'd have with 10.4 (Tiger) or 10.5 (Leopard). I've never used 10.3 (Panther), though. Poking around various websites, I don't see any mention of difficulties using DVD-writers under 10.3.9, but I can't give you a definitive answer. -- Rich On Sun, Nov 9, 2008 at 12:29 PM, stefan möller <stefan.moller at telgecity.com> wrote: > hello boys and girls at the macintoshguy g4 maillist! > > I´m an owner of a G4 800Mhz single processor "quicksilver unit with osx > 10.3.9 installed. > > > I would like to hook up a dvd-writer to my system without upgrading anything > exept maby a suitable version of Toast software for the osx10.3.9. > Is this possible?
