IMac (Intel) :: Intermittent Blue Squares That Crashes System
Aug 26, 2014
I'm running a late 2009 iMac, 2.8 GHz Intel Core i7 with 8 GB memory with 27 inch ATI Radeon HD 4850 512 graphics card running 10.9.4 OSX.
I will get spontaneous crash of the system that causes small blue squares over the entire screen. The problem will resolve after 1-2 restarts. I ran the system diagnostic disk and found no problems on the long and short versions. It is an intermittent problem as the display and system are running fine now but daily will have the crash occur. Once the spots are present the computer will be frozen with no response to keys or mouse.Â
Info:
iMac (27-inch Late 2009), OS X Mavericks (10.9.4)
I have a late 2009 Mac Mini with 8GB of OCZ 1333 RAM and an Intel X25-M 160GB SSD. Running 10.6 fully updated and installed from scratch.I have been getting out of the blue crashes while the system is most of the times idle. Can it be the RAM? It's reported fine as 8GB 1333 DDR under the system info. The Intel SSD runs latest firmware.
This is the log from the last crash which happened a little ago.

New iMac at first of year has always locked up with green squares (1/4") randomly on the open window. I have to do a hard boot to unlock the screen. This may happen 5 or 6 times a day but I'm finding no pattern. It happens in any software, mail, internet browser, extra programs and only using what I need at the moment, including mail and internet, hasn't worked. I've run disk utility - repair disk and repair permissions multiple times to no avail. I've reinstalled the OS Mavericks and Adobe Creative Suite programs (Photoshop & Premiere Pro), no improvement. Â
I purchased a high-end iMac specifically to handle high-demand video editing needs. But this happens when checking email or browsing the internet too. Here's a listing of the system from a "Panic (system crashes) log" from the "Activity Report."Â
Desktop crashing irregularly within the last week. No upgrades of late. Hardware checked okay. RAM checked okay. Rest SMC. Rebuilt volume. TechPro no issues. Latest crash report makes me wonder if isn't intego's virus x6. I've read many threads, but nothing is jumping out at me.Â

I have iMac 27 and screen problem on start up i have blue vertical lines, when it start i have a lot of blue dots and nothing else. when I connect outside monitor its showing the same.
Just installed lion and still the same problem when it starts blue dots, when startup in safe mode loads of blue lines and dots on the screen.
Sometimes, when my iMac has been "resting" and I then move the cursor using track pad I get a stream of black squares on the screen. The more I move the cursor the more black squares I get. If I switch off and then on the screen is ok. This is an intermittent occurrence.
My IMac crashes sometimes very suddenly, like in a power failure. It doesn't force quit or shut down, it just goes like somebody pulled the plug. It's usually possible to start it up again after 30minutes or an hour. The plug and lead seem to be fine. I tested it on another mac. The obvious suspicion would be overheating, but how can that be caused so suddenly (and how can I fix it)? It's an IMac Intel core duo, 20", 2 ghz, 2gb ram from 2006. I'm running Mac OS X (10.4.11) 2006.
i have had problems with my iMac, whenever i play the my game on Java, it crashes, yesterday it started out slow, happened like every 2 hours, but right now, when i get the error, only option to pull the plug, and then restart, and i open the game again and it happens within 5 mins, i made a video of what it looks like on youtube.(Btw, its lower half of the screen black, and the top is flickering) I cant do anything anymore, i can pause the music by keyboard, which i couldnt do before on the older crashes from yesterday strange enough, and i can move the mouse, but i cant click anything or w/e.Cmd - alt - esc doesnt work either
I have a 10.4 iMac. Recently when using it the screen starts to pixelate with large random squares and effectively makes the computer useless. Either that or I get moving multicoloured flashing squares (very psychodelic)Also on booting up the grey screen with the apple logo has dark grey sqaures and then when it goes to the blue screen has a series of smaller squares top and bootom. The booting up stops at this point.
I have ran the disk doctor, but it doesn't seem to have made any difference.
I have a problem with the display of an iMac G5 20". It shows up as vertical lines of small squares.
If I change screen resolution, the display will look ok for about half a second, and then it comes back again. Anyone had seen this before? (This is does not look like the usual problem with iMac and thin vertical lines.)
I run a dual 2 GHz G5 PPC (OS 10.4.10) - for the past 4-5 months I've been getting freeze ups for no apparent reason. These nearly always happen around the same time in the evening (around 11 pm) - although not every evening - probably 2/3 times a week. They can happen whether there is any activity on the computer or not. There is never anything on the console log at the time of the freeze up. I'm putting off an archive and install - though I've tried everything else - Disk First aid, Disk Warrior, permissions, fsck, cache cleaning, font checking, Memcheck, re-booting in safe mode, re-applying combo update, resetting the PRAM etc. - I've even tried replacing my secondary hard drive. I've also tried watching the Activity monitor around the problem time - unfortunately this is when it decides not to happen.
The Mac appears to run ok during the day (usually on by 7.30am) One other slightly odd thing is that sometimes at boot up a warning screen will appear and vanish in a 'nanosecond' - I think it could be the device removal warning -though nothing apart from my two internal drives may be connected. I also get this in the start up log 'family specific matching fails' on a number of usb items. Hope someone can help I'm running out of ideas.

During the first months of owning my new 15-inch MBP, I had at least three freezes. I remember there being a huge thread about this, which I can't find now. Happily though, my MBP no longer freezes, but I haven't done anything to it (other than software updates). So, was it a software glitch? Everyone were shouting about some sort of controller chip or something before, if I remember correctly...
Every time I try to access my users & groups it crashes my system prefs. I can't get to them at all to change anything. Similarly, trying to adjust parental controls for one of my kids crashes system prefs - it seems they are related... 10.7 Intel iMac.
How many Mac users have suffered from the problem of small coloured squares appearing at random on the iMac desktop? They can be wiped by dragging a window over them but they will eventually reappear. I have discovered at least three other threads where this issue has been discussed but our local Apple store is claiming that Apple haven't declared it as a legacy fault. It would be interesting to hear how others have been treated when presenting Apple with this fault. At first they thought it was the GPU but they now think that it is either the logic board OR the logic board AND the GPU together!! Being charged between £480 and £650 to repair a machine that is less than 18 months old is a bit much from a company that continually boasts about the quality of its products.
Very occasionally the screen on my iMac (early 08 24") goes blank and it makes an incredibly loud static sound that's independent of the volume control setting. The power then needs disconnecting to restart the machine. Haven't been able to tie it to any specific program. Apple Care asked I leave it on logged in on a new user account (at the time I originally thought it only happened in sleep mode, but have since discovered this is not the case).
It's happened maybe 3 or 4 times in the same number of months. I've only found one similar case on the net, with someone suggesting it was Safari 4 beta, which I've found not to be the case with mine. It's on extended warranty. I think there's something seriously wrong with it (it's already had the hard drive and power supply replaced).
My Imac has been acting up. When I restart the mac it takes forever to start up. It goes to the blue and stays there for several minutes and then will finally boot up. I am running Leopard on an Intel 17 in imac.
I have one of the 20" iMac G5's covered by the warranty extension for the intermittent shutdown problem. The problem is that I am out of the country, and where I am has very unreliable Apple service. It would be gone for weeks and weeks. I am considering flying back home to get my computer repaired. The computer shuts down multiple times a day without warning.
What are the chances I can find an AASP in the DC area who can do the repair in a day or two. I have read that the repair is only a power supply swap and can be done in 15 minutes. What do y'all think?
My other option is to just buy a new computer and worry about repairing this one in a year or two, which is a $2,000 hassle.
I have a problem with my iMac 2 GHz Intel Core 2 Duo (2 GB 667 MHz DDR 2 SDRAM), running OSX 10.6.5. OSX crashes and freezes all the time. Nothing works anymore. Sometimes it just freezes, and I can only move my cursor, but nothing reacts anymore. Sometimes the screen blacks (or sometimes blanks) out or shows the weird moving colours as shown on the photo I just took below: After restart, it often happens again and again. Then the iMac is fine for a couple of days, before it freezes again. Can anyone diagnose the problem from the info above?
Everytime I open an AVI in Quicktime it crashes. If I try to open an AVI through iPhoto it tries to open Quicktime and then Quicktime crashes but iPhoto doesn't. When I try to import these AVI's into iMovie it crashes again, this time taking iMovie down with it.
I have the following codec installed in Quicktime: AC3 Xvid DivX 6 (latest for Intel) 3ivx
Now here is the really weird part. I used to have a PPC Powerbook up until last week and the AVI files I am now trying to play in Quicktime worked fine even without any plugins so this is really weaird. Even still, if I came across a file that Quicktime couldn't play it never bombed out on me, it just produced a green or black screen with just some sound. The AVI plays fine in VLC but I need to edit them in iMovie.
I have faced some known symptoms of a problem for which I was not able to find any sound resolution. I have an account with which I am unable to login. When I enter login details for a session, the system immediately kicks me out showing a blue screen, logs out and goes back to the login window. An interesting observation during a sudden logout is that I spotted a vague image or window of an open application (probably Finder) at the background which is like 95% transparent in comparison to the Mac's desktop and therefore barely visible. The white-ish edges of that window is more distingushable though for a short duration.Â
I can ssh to this username and work remotely. But there is another username which has not been affected with this issue and works fine. The console logs show that loginwindow process is crashing everytime. Look at the output below. There have been notes with similar effects but with specific causes (e.g. MS Excel 2004 inc Rosetta, Blootooth peripherials, eBook Studio, Photoshop CS3 etc.) which might be related cases.

I have already tried booting in Safe Mode, deleting loginwindow.plist without success.

I used a new USB flash drive this morning to transfer my pictures to. It showed it was transferring them then the screen went blue and nothing responded. I shut down the computer and unplugged everything but now when I turn the computer back on it shows my home screen and I can see the mouse icon moving around but I am unable to 'click" on any of my programs and get a response.Â
My parents bought my younger sister a new MacBook a couple of days ago. She wanted me to install Windows on it so that she could play some games that she has.
So, I ran Boot Camp assisstant and installed Windows XP. XP itself runs fine. However, when I put in the disc from her MacBook that installs the Boot Camp drivers it gets to about Cirrus Audio (or something) and then crashes to blue screen. I tried installing the drivers a couple of times and then tried to reinstall XP and try again.
The last days appeared a problem on my IMac 21,5 inch Mid 2010, OSX 10.7.3. Without notice an intermittent sound appears very loud and the imac freezes. I have to re-initialize the machine. I've checked the console log and nothing.
Recently, tried leaving my iMac in sleep mode for hours but it keeps crashing with those Crash Reports popping up when I click to wake it. They mention Kernel Panics.(Also, been getting Kernel Panics randomly popping up when I start up at the desktop. This is a 2010 iMac which I purchased refurbished not quite a year ago Already emailed seller with issues, think I might just return it as seems like hard drive is going. , as to troubleshooting before I go this route?
Everytime I start skype while in windows, the computer crashes and I get the blue screen... I think it has to do with the sound drivers, because when I'm using msn messenger also in windows suddenly the microphone mutes itself.
I tryed updating the realtek drivers with no help, updated skype, no help, I uninstalled the realtek drivers and the laptop did not crash anymore but I had no sound, any advice like for example how to get the microsoft drivers to work on the laptop without using realtek??
For whatever reason with the microsoft drivers,I think the sound is trying to come out of the digital outlet, I can see the ligth inside the jack, but nothing comes out of the laptop's speakers...
