Stefan, I have had my Cube since new and it is the 450 as well. I have kept OS0 on her as well as kept up with the OSX. She is currently running 10.4.10, without a hitch. Best bet would be to start all over again, do not try putting a system onto a computer you just bought without wiping her off completely, including the OS9. Start by putting a new OS9 on but wiping the hard drive, Once you have a good clean OS9 then install 10.3 or older and work your way up until you get to 10.4.10. I am a firm believer of working up slowly to the current system. My Cube has been a very rock solid computer, but long surpassed as a computer I use everyday. She admin the LAN network I have for my studio as well as if I wake up at night I can slip in to that room to go online. I keep her on all the time. She has 1.5 gig of ram and 120 gig hard drive. Try those things I suggested I would bet she will be just fine as long as you go about it slow and put in all updates per system upgrade as you go. Skipping any upgrades as you go is not advisable, as long as you go 10.2.8 to 10.3 to 10.3.9 to 10.4 to 10.4.2 and on Kim Simmons On Jun 25, 2007, at 1:14 PM, Stefan wrote: > > Hi friends, > > > some time ago I bought a second (used) cube. > And I tried to install OS-X 10.4 on it. > > The Cube has nearly original condition but much more RAM. > 450 MHz, 20 GB HD, 1 GB RAM. > > OS-X doesn't really run on this cube.
