Nov 27, 2012 11:56 AM in response to hhhosaniby Kappy,You have a PPC computer so the highest version you can use is Leopard 10.5.8. You will need to shop at eBay, Amazon.com or search Google for sources of Leopard. Be sure to only purchase retail discs. Do not buy OEM discs with gray labels.

Nov 27, 2012 6:23 PM in response to hhhosaniby Bill Strohm,Just a comment here. I was curious about the "300 new features" in Leopard (compared to Tiger), so I bought a retail version of Mac Os X v 10.5, installed it on a separate partition of my 1 TB hard drive, and updated it to 10.5.8 via Software Update. Since I wanted to keep the ability to play Classic apps (mostly video games), I also installed Sheepshaver (not easy). Once I did that, I found that Classic games like Myst Masterpiece would run, but not very well. Periodically the games would freeze, although they played just fine under Classic in 10.4.11. Eventually I judged Leopard not worth it in comparison to 10.4.11, and trashed it. 10.5.8 was slower than 10.4.11, bigger with apps and features I don't use, and I didn't need Time Machine, since I back up manually to a second internal hard drive. So for me it was not an upgrade... again, just one data point if you are interested.

Nov 28, 2012 9:41 AM in response to Bill Strohmby Limnos,The original poster's profile is confusing since it says "Mac Pro" which is an Intel Mac, and "G5" which is is a PPC Mac. Unless the profile lists multiple machines it is contradictory. If it is indeed a G5 then Sheepshaver is not an option.
Upgrading to Leopard may be expensive. The discs could cost $100+
Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac". Write down what it says about "version"and report that here. Now continue to "More Info..." Copy and paste the information here, but omit the serial number and Hardware UUID (if present).

A dual 2.3 GHz G5 is obviously not a Mac Pro, even though the OP calls it such. (OP probably is referring to the external chassis tower configuration which is similar to the Mac Pro.)
Sheepshaver is in fact an option on a PPC PowerMac; I have installed and run Mac OS 9.0.4 on my 2.7 GHz dual-CPU (early 2005) PPC PowerMac with Mac OS 10.5.8.
The purpose of Sheepshaver is to provide a Classic Mac OS which will run on versions of Mac OS X which no longer support that OS. It is apparently written in Universal Binary which allows operation under both PPC and Intel Macs. I did have problems running game apps using Sheepshaver, although they opened with no problem and would play video/audio correctly. Problem was that the games froze intermittently, so I opted to go back to 10.4.11 with Classic installed, where there are no problems with the games.
I agree that the current e-Bay/Amazon prices for Leopard are outrageous; my copy of 10.5 cost $104 with tax. I found it not worth the "upgrade," since its additional features do not compensate me for the slower operation and loss of Classic.
