Q: My computer will run on 10.5 and is currently on 10.4.11. Where can I obtain this reference release? 10.6 is beyond the spec of the machine.
I have inherited a 2005 IMAC G5 which will run on 10.5 Leopard but not 10.6 Snow Leopard. For my purposes it is still a serviceable bit of kit but it runs on 10.4.11 presently. I have upgraded the memory to 2.5GB but cannot seem to locate a copy of 10.5 anywhere. Does anyone know where I can obtain a legitimate reference upgrade from? Many thanks.

Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).
If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:
MB427Z/A Leopard 10.5.1 install DVD
MB576Z/A Leopard 10.5.4 install DVD
MB021Z/A Leopard 10.5.6 install DVD (single user)
MB022Z/A Leopard 10.5.6 install DVD (5-user family pack)

After you install the base 10.5, download & install the 10.5.8 combo update at http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
The DVD should look like this
Caution - Leopard does not support classic mode. So, if you currently open OS 9 apps in classic mode, you won't be able to do this if you upgrade to Leopard.
