Can I buy a 10.5.8 DVD if I own a 10.5.1 DVD?

Question

I bought Leopard 10.5 retail. My DVD is 10.5.1. Is there any way for me to (legally) get a 10.5.8 DVD or image?
I'd like to have a more recent version of this OS -- I still need it for my G5. With 10.5.5, for example, Apple added to ability to install printer drivers without a full OS restore.
Any ideas? (Note 10.6 won't run on a G5.)

Answer 1

According to some online findings, inconclusive in my searches, indicates
the fourth release on DVD of Leopard 10.5(.6) was the last retail disc one
can buy; one that would not be a download Combo update, or not be of a
machine-specific restore/install set, included with a specific new Mac model.
So, on a preliminary basis, Mac OS X 10.5.6 may be the last retail release
on DVD for any computer capable of running Leopard, which did not ship
with a custom machine-specific DVD of OS X 10.5.6 or later. If one exists.
And the current history shows Leopard 10.5.8 to be the last version of OS X
to run in PowerPC architecture; Tiger 10.4 was the first OS X system shipped
with the newer Intel-based Macs. Usually in a computer-specific version.
The versions, & listed download update steps, of OS X 10.5 are listed at wikipedia
http://en.wikipedia.org/wiki/MacOS_XLeopard
You could make a machine-specific disk image of an installed and updated 10.5.8
system; or make a clone of a completely healthy & updated system for a reference
system on a bootable externally enclosed hard disk drive. This could be used for a
number of important time saving purposes; including maintenance, repair & restore.
{I've saved the Combo, java, security and other updates from a recent 10.5.8 full
installation, for all steps above the 10.5.0 retail install DVD. ~ If you do one install
from scratch, save all of your files. And for the one computer you use, save at
least one fully functional bootable clone that is fresh; one to clone-back from or
use Disk Utility to save a fresh completely new install as a .dmg file.}
Perhaps if you call Apple Sales Support, and ask for a product specialist, they may
be able to answer to the inquiry of which level does the final retail DVD OS X 10.5
version supply to someone wanting an archive install disc for those computers which
won't upgrade past Leopard 10.5.8. They should be able to tell you the last retail step.
IF you go there (1-800-MY-APPLE) and find out, please post back. I may want one.
Good luck & happy computing!
