I'm considering upgrading from 10.3.9 to Tiger.  Will Tiger overwhelm the 1.8 GHz G5?

PowerMac, Mac OS X (10.3.x)

    Tiger should run fine if it meats or beats these requirements, not especially so with Leopard/10.5...


    Tiger Requirements...

    To use Mac OS X 10.4 Tiger, your Macintosh needs:

        * A PowerPC G3, G4, or G5 processor

        * Built-in FireWire

        * At least 256 MB of RAM (I recommend 1GB minimum)

        * DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation

        * At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools  (I recommend 20GB minimum)



    See Tom's, (Texas Mac Man), great info on where/how to find/get Tiger...




    Or Ali Brown's great info on where/how to find/get Tiger...

    Will Tiger overwhelm the 1.8 GHz G5?

    On the contrary, Tiger is highly optimized for the PPC processors and runs terrifically on a G5.


    Tiger runs wonderfully in G4 machines with 1/3 of the processor speed, so there is no worry regarding negative processing impact in your 1.8GHz machine.


    Tiger (also) most assuredly runs with more stability than Panther, and requires much lower overhead than Leopard.


    Tiger is a refined OS.

    I have Tiger upgrade disks that I own and used to upgrade my G4 to Tiger several years ago.  Tiger is currently running on the G4. 


    Can I use the same upgrade disks to upgrade the G5?

    Is it a Black Retail Disc, or an Upgrade/UptoDate Disc?

    The box is black with a silver X.  The instruction booklet on the inside says "Mac OS X v10.4 Tiger Installation and Setup Guide".  The disk says "Mac OS X Tiger Includes Xcode 2 Install DVD".

    Should work, though if it's not a Family Pack it's legally only supposed to be installed on one computer.

    It works really well on this machine.

    However, I think the best use of matched software for this machine is 10.4.11

    I have to disagree with Grumble here. When I still had my G5 single 1.8 the upgrade from 10.3 to 10.4 and to 10.4.11 is was something I never regretted. From boot time, to everything else I used that machine for on a daily basis was faster. So not only do you get more "supported software", you get a more responsive system overall. As long as you have maxed ram I do not think you will be dissappointed.




    Hope it helps!
