Mac OS X 10.5.5 released through Software Update
It hasn't hit Apple's software downloads page yet, but reader reports are coming in that Mac OS X 10.5.5 is loose in the wild. Check Software Update to see if the big cat is available in your neighborhood ... or, possibly a better idea, wait 24 hours for the early adopters to see what breaks. You can see the full release notes here or in the continuation of this post.
"The 10.5.5 Update is recommended for all users running Mac OS X Leopard and includes general operating system fixes that enhance the stability, compatibility and security of your Mac."

I wonder what "Includes extensive graphics enhancements" entails?

Unless they reintroduce 256 color support for my MB Pro, I'm sticking with 10.5.2.
I needs my Diablo II :)

I can confirm that Diablo 2 works now.
WOOT!
Didn't work in 10.5.4.
Did a fresh install just now, patched up to 1.11b, then to 1.12a, and it works flawlessly in OpenGL mode (haven't tried Software) in both 640x480 and 800x600.
This is on a MBP, btw.

That's in "Thousands" and/or "Millions" colour mode, btw. No 256 colour option is presented in the Diablo 2 launch UI.

I'd give you some grief over "needing" an old game, but I'd die if I couldn't play Quake II, so I know just where you're coming from. :)

don't have Diablo 2 installed but Fallout 1 & 2 both work now (which didn't before)

Ah, 10.5.5. A nice rounded sequence of numbers. Installed, and everything working smoothly.

When's that awful bug gonna be fixed? You know the one, where your dock looks nearly useless graphically and Stacks that expand into invisibility when you return from full screen playback?

What is with the snaky "There's the Apple specificity we love so well" The included a lot of information on this update (which you included in your post).

My iMac is now showing funky flakes.. The graphics are garbled when I log in. This is what the desktop looks like when I log in.

If I move an icon or mouse over the dock it'll go away from the area. If I hit Dashboard it'll go away fully.
Everything else seems to be working great, but this little graphics issue.

Oh man, you aren't serious! Should I wait or should I go... I'll try it.
marian said 6:05PM on 9-15-2008
My iMac does not have the same issue.
Everything running smoothly here.
Matt said 6:11PM on 9-15-2008
That doesn't look too good. I saw some distortion like that shortly before my mobo got fried on a g4 powerbook a few years ago. Might want to back your things up ASAP.

Try resetting the PRAM?
