Power Mac G5 :: Huge Artifacts After 10.4.11 Update
Nov 15, 2007
During installation, my graphics got all screwed up. You can see a screenshot of what's going on at this link: [URL]. I'm actually writing on the defective computer, so it's hard for me to see what's in the screenshot. Here's what I did so far. I tried removing half of the RAM first, then the second half, the problem persist. I rebooted on a different system, it's still there (so not software). I tried Hardware Test utility, it says everything is fine. I unplugged the Video Card, cleaned it a little along with the connectors, nothing. It happened DURING the update to 10.4.11 (not after I rebooted). I'm pretty sure I can take screenshots of it, so it's not simply in the connectors to the monitors. It happens on both my monitors (also when I unplug one of them).

I have been reading that several people are seeing much cooler temperatures on their Mac notebooks and they think it's due to better graphics drivers with the update to 10.6.3. I however thought about the huge performance hit in OpenGL going from Leopard to Snow Leopard (probably same thing). So I decided to check my OpenGL results after installing 10.6.3. However, I didn't check my xBench results before upgrading to 10.6.3. I went and found an old result which shows 67 points for "OpenGL Graphics Test." My new result for "OpenGL Graphics Test" is 111 points. When I check the xBench archives, people with rev "C" MBA's with 10.6.2 all show OpenGL Graphics Test scores in the 60s.
If this is correct, we could all have some big improvements that really show huge effects on the MBA. It should help everyone running Snow Leopard. It should lead to graphics performance gains and lower heat due to graphics demands. Could someone else running 10.6.2 on a 2.13 GHz CPU MBA run an xBench test before the 10.6.3 upgrade? Then upgrade to 10.6.3 and run another xBench test. Then please report back here with your results for OpenGL Graphics Test and hope this result is great for all of us. I believe this would be a big improvement for the original MBA too?

I have a problem described by Apple in document Power Mac G5 (Late 2004) 1.8GHz models stop responding randomly.
How can I update the firmware because my G5 1.8 screen is blank? Thought that I could make my G5 1.8 as a hard disk for my MacBook, or I may try to update over the network. Is there a risk of corrupting my MacBook if I try?

Hopefully somebody can tell me what's wrong. because it's getting basically impossible for me to do anything on 3 year old MBP. These are artifacts show up mostly when I use Safari. In fact when I CTRL T for a new a tab that's when it's the worst. But it happens when I'm using Photoshop sometimes and other programs. but anyway it seems to be getting worse.

Flash 10.1 released today... Video artifacts when using flash?
I downloaded and install the new Flash on two newer Macs and experienced screen artifacts when I tried to run certain flash sites... Just me or others as well?

I got this card:
XFX HD 4890 8750M 1GB DUAL DVI TV
Product Code: HD-489A-ZDFL
It isn't working in my MacPro properly. It displays artifacts or reboots the system under BootCamp. After 15 minutes of idle warm up it works OK... I've send it to XFX for RMA and they've tested it and "NOFAULTFOUND".

I don't know where post this, but I'm getting since yesterday a weird behavior in OS X Snow Leopard.
I don't know if is related to XCode/iPhone SDK or what. Sometimes, with no apparent reason, the menu of the application become FULL white.
Then in the emulator I get distortions in controls (the edit not show characters when input, but the control are getting it).
Also I lost the Command-Z in the xcode editor. Other glitches are around but I don't remember it right now.
I have a white macbook MacBook2,1.

I'm gonna apologize in advance if this was already posted, but I'm not quite sure what the technical phrasing for this issue is, so I could've missed it in search. I'm running a Macbook Pro 17', manufactured around September 08. It's currently running OS X 10.5. I received it from my school with the computer already set up and all the software pre-installed, so I personally don't have access to things like the boot disc and other base software, but I can get a hold of it if it's necessary. The crash: Somewhere along the boot-up process, or somewhere soon after boot-up, the computer will freeze and a bunch of pixels will rearange themselves. I wish I could show a screenshot, but the best way I can describe it is that these little jagged stripes of pixels will move to places they aren't supposed to; for example, below the little spinning boot-up circle on the initial boot screen, there's a block of pixels kind of shaped like --.--_ that pulses darker and lighter in time with the pixels on the bottom of the circle, so they just seem to be transposed from another position on the screen. If this happens during boot-up, which is most of the time (on the screen with the dark grey apple on a light grey background), then the computer will try to boot up for a while, then the artifacts will run in stripes down the screen and a window will come up telling me to restart my computer. Sometimes--usually when I've shut it down and taken out the battery and let it sit for a while--it'll get past boot-up, and I'll get either almost to the desktop or even get a couple minutes of actual use before the artifacts appear again and the computer freezes.,......

My macbookpro (leopard) is freezing during Macosx Update, It asks for a reboot, then the timeline stays forever in the mode "configuring setup..."... I can still access to volume control and brightness shortcuts but thats all.
the timeline is blocked. only solution is to power off manually!
I can't update leopard... Did you experiment this also?

I've had my 27" iMac (3.06GHz) for a few weeks now and yesterday I noticed some weird artifacts appearing on the screen, very randomly.
They will pop up all over the screen but if I "Show desktop", they will go away for a bit but sometimes reappear again in different areas of the screen. I restarted the computer but that only temporarily fixed the problem.
Anyone know what's causing this and how to fix it?

When I loaded up the same page on my pc and mac side by side that the safari version of the page had very poor pictures, i.e. you could see loads of artifacts of the jpg compression. The page I loaded was [URL] and you can see the picture of mr Mac and mr PC stood side by side. I have tried looking through Safari preferences but don't see anything anywhere that would indicate picture compression? Another point I think I should make is that the mac is a macbook and it is running over a 54g network.
So I thought maybe it realised that the speed wasn't up to scratch and therefore adjusted the picture quality itself? Needless to say I did plug in an ethernet lead and after a couple of refreshes the page loaded and the pictures were perfect. Which sort of answered my question? but 54g is a fast enough speed to have high quality images and I thought I should have the choice of selecting this myself?

I've got a bunch of 1080p videos in MKV. When I play them using VLC and switch the video to a different scene (say 20 minutes ahead), artifacts appear throughout the video for a few seconds and then it disappears. I have this on about half of my MKV 1080p Videos. Is this normal? This only occurs when I manually switch to a different scene. If I play the video straight through then it plays fine. This occurs on both my Mac Pro and Windows Vista Computer. Are my videos corrupt? I don't notice this on my Mac Pro when using Movist when switching scenes.

I've recently begun seeing random, darkish rectangles appear and disappear while watching a streamed Netflix movie. Last night when it began happening, I disconnected my laptop and substituted a friend's, whose is almost identical to mine: hers is early 2011, mine is late 2011. Hers showed no rectangles.Â
Several facts:
-- viewing in fullscreen mode
-- using video mirroring to display on TV
-- using WiFi
-- latest OS and Silverlight software being used
-- no other apps open
-- both laptops are MBP 13" Â
Can anyone speculate as to what these randomly sized rectangles might be? Are they artifacts of video compression or streaming? Could they in any way indicate a failing video card?  Â

I just upgraded my MacPro1,1 to OSX Lion. At the same time, I was having some problems with my video card and replaced it with a NVDA,Display-B. It seems to be the same as what I took out but am getting some screen artifacts as well as windows jumping and distorting.
A shot of the artifacts is here: [URL] ...

I bought recently (this week!) an PM G4 MDD 1.25DP with radeon 9000PRO, 1.25G of RAM, combo drive and two hard drives with 200 gigas both of them. This is my first Mac! I'm realy in love with it.
The first one is:in the morning when I try to start my G4, only after 30 or 40 attempt I get it. I push the power button so many times.... I pull away the power cord in same "so many times" until the Mac "wake up". After that it's work especially fine. I can shut down and restart the Mac unexceptionally.
The second one is: when I try to update the Leopard and when they ask me to reboot, the progressing bar showed never headway. But others updating, e.g. the Itunes, proceed like a workaday.

Why does Minecraft look like this on my iMac? Is my video card messed up or something? It all flickers and changes as I move and look around. And it's not the mods, it did this stock, before I install the MrMMods.

Have OS X 10.5.6 on an new Intel IMac 24. When I use Google Earth or run X-Plane I see these random polygons/lines appear as i move the mouse. All other applications seem to be okay. anyone else seen this? Apple support say they know of the problem but there was not sufficient momentum to look into creating a fix.

I have an iMac G5 (rev. B with ambient light sensor) which has suddenly started having a problem where the entire screen is covered with pink artifacts. The iMac had been left on overnight and when waking up in the morning I found the screen looking like this and now it continues to stay like this no matter what I do. I have attached a screenshot and was wondering if anyone might have a clue what has caused this to happen

I was using Audacity on my mac running 10.4.11, on some seriously large files (85MB mp3s were exported from these original wav files!), when during this these red vertical lines started popping up on my screen; mainly where a window had been moved. These lines haven't gone away and I'm not sure how to fix this problem. I'm stumped! Having repaired permissions and run the Disk Utility from the Install disk, I'm at a total loss. The intro/gray screen, apple logo doesn't have the red lines, but every other screen does.

We just updated our G5s here at the lab (QuickTime and Garageband ), and now the sound output is extremely distorted and crackly regardless if its a video on cnn or a song off iTunes. Tried Zapping the PRAM and repairing permissions, even reinstalled QT from the standalone installer on apple to no avail.

I got up and tripped over the power cable and It popped out (thanks magsafe! ) but the computer immediately shut down. I plugged it back in and started it up to see my clock was messed up. I changed the clock and redid the update. Everything seems to be working now but I was just wondering if anything else could have happened?

For some bizzare reason my Mac wont restart or update, not to sure when the problem started as I normally just put it into sleep! But basically when I click update it says the updates need the Mac to be restarted, I click ok. It basically logs out and goes to the Username screen to login. Same story when trying to restart/shutdown; just goes to the login screen.Â
I'm tempted to do a OS Wipe and start Fresh! However it's going to take 3 hours to download the latest OS! Patients isn't my strongest point !Â

I got my MBA about 2 weeks ago, and in 3 different occasions some windows and parts of the desktop would show display artifacts. I am attaching snapshots. I didn't recognize any specific pattern that could cause this, and the CPU was not overheating when the fact happened. Every time it was sufficient to reboot the system, and the problem disappeared. I am worried it might be a hardware issue, maybe related to the integrated graphics. Should I have the MBA replaced?

I own two Intel-era Mac Pros, one at work, the other at home office.couple months ago both started having the same problem: a mix of freezes/hangs and weird graphical artifacts showing up on the screens.Usually I need to reboot. Usually a reboot fixes the problem for a while until it recurs. If it was just one computer, I'd figure disk problem or graphics card.But the fact that both have been affected at the same time makes me suspect some software issue or possibly a trojan/virus.
