I have a dual processor G4 (dual 1Gh PowerPC) with 768 MB SDRAM. I know that it's only supposed to be able to run 10.4.1 (which is what I have installed, but I've heard of being able to install 10.5 if you do it on an external hard drive?

I need to run Bento and Aperture 2 on this machine. Any way that's possible?

G4, Mac OS X (10.4.11)

    Your computer can run Mac OS X 10.5.8, and it can be installed normally. All G4s can run Mac OS X 10.5, but if they have a CPU slower than 867MHz, it can't be installed in the standard way.

    Thanks, very helpful. I'll give it a try.

    The requirements for running Aperture 2 exceed the minimum requirements for just running 10.5, not sure if the G4 is up to the task, also depends on your video card in that machine:

    Do you have a MDD (max 2GB RAM) or Quicksilver (max 1.5GB RAM) model? You should max out the RAM in either case as 768 MB is not enough (for Aperture 2).

    You mention that it can't be installed "in the standard way" - I assume this is with the startup CD/DVD. What way would I go about installing the OS?
    Also does anyone know if I can use 10.6 that came with a recently purchased Powerbook? Want to see if I can use it on my G4 Quicksilver. Thanks.

    Perform the installation on another PowerPC Mac, either onto an external drive followed by moving the drive, or by hooking them up with a FireWire cable and starting the Quicksilver with the T key held down.

    does anyone know if I can use 10.6 that came with a recently purchased Powerbook?


    No. A PowerPC Mac can't use Mac OS X 10.6 or any OS which came from a disk designed for a different Mac model.

    This information is meant for R. Harris and isn't applicable to triglyph.

    Thanks, I'll try it from my G5.

    I understand it's not possible to just "move" an OS System. Isn't there some software (I vaguely recall) that will move a system? Any recommendations on an app that won't result in days of frustration?

    /Applications/Utilities/Disk Utility.app can duplicate the contents of one drive on to another drive and retain the Mac OS X file access permissions.

    Also, Carbon Copy Cloner, which is also a good tool for regularly scheduled efficient incremental backups, copying over only files that have changed since the last backup.
