Notes on some OS X 10.6.3 graphics driver issues (7300GT AA issue, some ATI GPU issues w/PPC Games under Rosetta)
I'd mentioned last week that an iMac owner w/7300GT graphics wrote about display/graphics problems after the 10.6.3 update and yesterday saw this post on the OpenGL mail list:

"Multiple of our users report that rendering of anti-aliased GL_POINTS on the Nvidia GeForce 7300 GT seems to be totally broken since upgrading to 10.6.3. Downgrading to 10.6.2 fixes the problem. Other tested ATI Mobility X1600, GeForce 8600M, 9400M, GT-120 don't show any problems in this area, so i guess it is a driver bug for 7300/7600.
They report:

"...dots "barely" show up at the edge of screen and do not show up at all in the center. they appear as green dots (almost pixel sized lines actually) and the size and color arguments have no effect."

When I installed (upgraded to) OS X 10.6 originally I chose to install Rosetta (optional install) as I had some older PPC Mac games that I wanted to still be able to run. (And as noted earlier, some printer/scanner drivers are still not native Intel code and require rosetta.) I haven't tried any of my old PPC games under Snow Leopard yet, but had a reader with two ATI GPU iMacs report a problem with a PPC game (Dungeon Siege) after the 10.6.3 update.

"10.6.3 Graphics Issues - source of problem
I encountered identical graphics issues on two different model iMacs immediately after updating to 10.6.3 from 10.6.2. (2007 AL iMac w/Radeon HD 2600 and an early 2009 iMac w/Radeon HD 4850.) I used the 10.6.3 combo updater on both iMacs. Had reinstalled 10.6.0 and upgraded to 10.6.2 on one iMac just one week ago.
system log:
Apr 4 14:15:04 Gryffindor Dungeon Siege[948]: Error loading /System/Library/Extensions/ATIRadeonX2000GA.plugin/Contents/MacOS/ATIRadeonX2000GA: dlopen(/System/Library/Extensions/ATIRadeonX2000GA.plugin/Contents/MacOS/ATIRadeonX2000GA, 262): no suitable image found. Did find:\n   /System/Library/Extensions/ATIRadeonX2000GA.plugin/Contents/MacOS/ATIRadeonX2000GA: no matching architecture in universal wrapper

Just check out the indicated files and the similar ones for other graphics cards and you will find they are Intel only.... It's back to 10.6.2 for me. I can count on one hand the Intel Mac games that interest me.

Update: Before I had time to even call to ask about this, I recd a reply:

"Re: Dungeon Siege regression in 10.6.3 on ATI R6xx, R7xx hardware
Hi Mike, on the Dungeon Siege corruption and error messages, two bits of news:
a) We've tracked down the change where we broke it. We'll work to get a fix as soon as possible.
b) it looks to me like the console error messages are not related to the corruption. I haven't yet tracked down what they mean, but I see them even in MacOS X 10.6.2 where Dungeon Siege looks fine.
Also, obviously, I'm bummed that we introduced this regression, and didn't catch it in our testing.
Sorry, folks!

If any reader has seen similar issues (or not) with 10.6.3, sent a note with details. Thanks.
(My main work machine is a refurb 2007 iMac running 10.5.8 and I have no plans to upgrade to SL on it anytime soon. However I will try some PPC mac games I have installed on the MBP with 10.6.3.)

Original Apple/Mac Nvidia 6800 ULTRA (not GT) DDL AGP card for Sale

Legit Mac model ordered directly from Apple. (Not a Flashed PC card.) Like new in original Apple Box. Bought for $599 in Fall 2004 and only used a few hours for the reviews here. I'm asking $300 US (USPS Money Order only). I'll pay shipping to a USA address. If interested let me know.
For more pix/info, see my original review of this card (tested in my original G5 tower) here. The card supports two 30in DVI Cinema Displays.

Apple Docs on iPad Troubleshooting (including WiFi, Bluetooth)

BTW - finally today I had a chance to actually try an iPad in-store. (The road-trip last week to do that got sidetracked - aka t-boned.) When the iPad was first announced I thought I'd pass on the first rev (wait for a later gen with more features/more storage/perhaps lower price per GB), but after seeing some of the TV ads, I'll admit I wanted one. Today I was only able to spend a few minutes playing with one, but my first impression was positive. I'd definitely like to get one eventually.
And while on the subject, here's some comments a reader (Developer) sent on Monday regarding his iPad:

"24 hours with my iPad
Bought the 16GB model - I'm using it for development so I don't need any thing fancy. It is completely amazing. Not just a big iTouch. Apple has done it again. My inlaws are all drooling during easter dinner. I think they are all going to buy one.
Sent from my iPad
(after seeing (linked earlier this week here) issues some have seen with WiFi, heat, etc. I asked him about that.-Mike)
No overheating. I haven't had the device outside much. (some users in the sun noted iPad shutdowns/warnings). Cousins did play NFS for about 30 min on Sunday with heavy use after. No problems.
The wireless at work sucks but it seems to do ok there. I have a Timecapsule 1TB at home and it is lightning fast over N-only.
-Logan C."

I'm trying hard to resist the urge to order a first rev model but I'm going to put my 6800 Ultra DDL card on Craigslist and if it sells, I'll use those funds to offset the cost of an iPad...
