    I've only been using a Mac for a few months. I was able to buy a used PowerMac G5 for a very good price as I wanted to learn Mac OS X. The system has Tiger installed but I also want to start using Leopard (it seems really cool).

    Is there a way I can install both Leopard and Tiger on my Mac? I would appreciate if anyone could share some pointers and tips.

    Thanks :apple:

    Partition the hard drive into half then install tiger on a partition and repeat with leopard on the other..


    Backup the info from tiger first before doing this..

    How can I choose Leopard or Tiger when the system boots?

    You can install 10.5 on any volume and select it as the startup disk.

    For instance: a 2nd partition or another internal drive or an external drive (though it would be slow compared with an internal drive).

    Hold down the "opt" key.

    Thanks for the info. I have a wireless keyboard and notice that it doesn't become fully operational until the login screen appears. Will I be able to hold down the "opt" key on the wireless keyboard?

    Is it a USB wireless (non-Bluetooth)? Otherwise, it should work on startup. I have the Apple BT keyboard and have full control from power-up.

    edit: I'm on a MBP. I'm not sure how it'll work on the G5. If it has the Apple BT adapter, it should work the same.

    It's a BT keyboard (the white one). Good to know that it should still work on startup. Thanks for your help on this gr8tfly.

    Just make sure you follow/ read all the steps throughly. I tired this a few days ago and ended up having to format my hard drive all over again to get back the partition I tried to create for Tiger. I eventually gave up, and just installed it on my Ex. HD.

    What steps are you referring to? Is the a document that explains how to do this?

    The system I have was used by a video editor. It has two internal drives - a 160GB and a 300GB. The 160GB has Tiger the 300 isn't used for anything useful. Would it be best to partition the 160 drive into say two 40GB partitions - one for each OS - and leave the remaining for the Home directories (/Users) - perhaps as a way to share it across both versions of Mac OS X or would it best to fully isolate each OS from each other with its own /Users?
