What OS will a G5 10.4.5 run?
Mac OS X 10.5.8. If needed, check sites such as Amazon or eBay for a retail Mac OS X 10.5 DVD.
Do I have to start with 10.4.5 or can start with 10.5.8? I had to install a new hard drive and do not have the software it came with.
You can start with the OS on the retail DVD, but won’t get iLife or the Apple Hardware Test that way. That OS will be either 10.5, 10.5.1, 10.5.4, or 10.5.6.
Thank you for your help
Note upgrading to 10.5 or later requires you to lose access to old Mac OS 9 applications you might have that are known as Classic applications. If you don't have applications from prior to 2001, this is not a major concern.
