RATTUS  I mistakenly installed this some time ago before I realised it wasn't necessary and now I can't figure out a way to remove it safely, can anyone help please? I have an iMac G5 running Mac OS 10.4.10 if that's any help...

ANONYMOUS  How do I remove this P.O.S? It killed my airport card, stupid crap driver.

Thanks

ANONYMOUS  On the download page for mac (latest version is 4.5.6 BTW), a click on the dmg file redirects you to "http://support.ati.com/ics/support/DLRedirect.asp?fileIDExt=9f3d342d38e036a9137ef3e270d9d79c&accountID=737&deptID=894", which if on Safari creates an endless popup loop, and on Firefox creates a page that keeps reloading itself with javascript errors.

In other words, you can't download the file until ATI gets their ass together and fixes the download page.

SHERUB2001@YAHOO.COM  Something tells me from LOTS of experience (of screwing around with my computer needlessly) that if your Mac works fine BEFORE you install firmware/software, you probably don't need it in the first place.

This won't "over-clock" your video card so why take the risk of having something horrible happen to your Mac.

Leave it alone!!!

ANONYMOUS  Tried everything possible to input a trouble ticket. All 4 browsers on my Mac, IE on a Windows machine. Can't choose the "manufacturer" pull down. Can't submit a trouble ticket without this. No way to get through to support. REALLY FRUSTRATING. These guys obviously don't care about their customers.

Black screen of death:

Here is my problem. installed the card, installed the software on the CD, everything was fine. Installed the latest firmware for the card, everything was fine. Installed the latest Radeon software, system wouldn't boot. Get the black screen of death after reboot. Will only boot in safe mode. Tried repairing permissions, etc. Still won't boot. I backed everything out. They loaded the software from CD again. Everything fine. I would like to load the latest Radeon software update, but I need advice about how to avoid the screen of death.

GOAT  Against my better judgment I went ahead and installed this on my new 20 G5 Imac, with the 128MB ATI 9600. Installed no problem, no permissions problems either, wow!

I tested it with Airburst Extreme, and Luxor. You create profiles for each application and then go from there.

Noticed no difference in Luxor(I'm thinking it doesn't really use Open GL)

Airburst Extreme, ran well when I set it to Highest Performance in the presets. When I set it for quality, It barely ran at all.

I'm thinking OS X handles everything just fine on its own. If you want to tweak a little this works nicely.

Hint: once you run it through the System Preferences is shows up in the Recent Items menu, its also in your Utilities folder, why did they bother adding it to System Preferences?

ANONYMOUS  Although not stated, the 4.5.5 updater will work with the 9550 chip in the new iBooks as well...

JUSTWORKS  Works as advertised on my 15" G4 PowerBook running OS 10.4.2.

Repaired permissions before and after the installation, I was amazed that the ATI Displays installer did not even mess up permissions. Looks like they got this update done right.  
(Version 4.5.5)

ANONYMOUS  This software is ONLY requried if you use any of the special features built into the card, like display rotation, or certain game enhancements. Otherwise, the ATI cards run perfectly fine without this. The ATI Universal ROM update, which is a separate download, is all that is really needed.
