PowerPC :: IMac G5 PPC Crashing - How To Fix It
Aug 2, 2010
I've got a 2005 iMac G5 PowerPC 1.8GHz running Leopard. It's been running absolutely fine since I had it (upgraded to Leopard for at least 18 months) but randomly a week or two ago it's started crashing.
Sometimes two or three times in a row, then it's been 2-3 days without problem.
The display starts flickering, usually the mouse pointer can still be moved but after 10-20 seconds or so it will just crash and I have to restart by holding the power button down.
There's nothing in the crash log. I've run the hardware test and checked the memory and everything is looking fine. I've completely reinstalled Leopard and also cleaned out the fan in case it was overheating that was causing this.

I have an iMac G4 and it keeps crashing. I've zapped PRAM, bought more RAM, re-formated HDD, installed Mac OS X over and over, I don't know what else to do. Even if I boot it up and let it run, it will eventually crash, but at random times. If I re-boot right after it crashes, it crashes again, but if I wait, it doesn't.

My powermac keeps crashing about after a few hours of use.
I installed some new samsung 1gb x 2 ram.
The hardware test and techtool show no problems but I'm positive the ram is the culprit.

This G4 was upgraded to OS 10.1.5 and for some long time was quite happy to search the net using Mozilla 1.0.7 However it now frequently crashes. Is this because that version of Mozilla is no longer stable? Can a later version or even Safari be installed on this computer? Is it possible to upgrade the computer to OS 10.4 + so that later browsers can be used.

I bought a Powerbook G4 about 2.5 yrs ago, top of the line, new from an Apple Store and its been great. However over the last 2 months, its developed this habit of crashing/sleeping/going blank while it Itunes is streaming music, and/ or while Safari is up. Last night it did it while I was recording a Live DAT into garage band. I used to be able to hit the space bar or any key, and it would come back briefly, crash, repeat etc until I restarted. Now however, its just suddenly black. nothing. All I can do is take the battery out for a little while, wait, put it back in, and then restart. I've backed up everything as a precaution. I am diligent about uploading software updates, and I run MacJanitor from time to time...
I probably have 1200 songs, 15TV shows on Itunes, and 1000 pictures on iphoto, So I would hope my hard drive still has ample space.

I have a Powerbook G4 1.67GB with 2GB ram.
I am constantly having problems with the laptop shutting down when it is just on battery. It doesn't do this if I am plugged into power.
It does this on a random basis whatever program I am running but generally at 80%. I currently have Leopard as the operating system.

I have an older 15" powerbook Titanium. About five years old now. Been working pretty well all five years, save for an external hinge I had to replace. Last night, the computer started buzzing from the insides, a buzzing reminiscent of a distant chainsaw. The program i was working in (firefox) just went to the pinwheel of doom and never recovered. I moved to the finder, which did the same. I forced booted. Same noise. Same problems. I can use programs for a few minutes, but then they pinwheel of doom and the computer freezes out.

All three of my browsers (Opera 10.10, Firefox 3.5.6, Safari 4.0.4) crash repeatedly when accessing www.nytimes.com (most common site). I am running OSX 10.5.8 on an iMAC G4 with 768MB RAM. I ran Onyx and repaired the permissions but to no avail. Other websites have failed but the nytimes site causes instantaneous failure.

For the last couple of weeks, while using various programs (Firefox, Word for Mac, etc) my computer (or the individual program) has crashed. Also, After sleep, the G5 would not awake even if I pressed the power button. I changed the Energy Saving schedule to 15 minutes for both settings. Before it was an hour. We had to actually shut of the power supply and turn it on again. Then it started up.

iPhone 3GS, iOS 5, Main syncing computer is MacBook

My imac is 10.4 tiger which over the years is now updated to version 10.5.8. It regularly crashes and is getting worse - at least twice a day then i have to turn it off with the power button. When i go to reboot a folder with a question mark appears on the screen. I usually then have to turn it back off and wait several hours for the mac to reboot again...

I am having trouble with crashes. It seems to be finder. I have Lion 10.7.4 I have looked on the net for answers and they all say to delete the finder prefs. I don't see any in library/preferences? Where are they? Sometimes when in either photoshop or Indesign and I try to save the folder is blank, when I know there are files in it.

For some reason, both Safari and FoxFire are crashing on my IMac. I am using the smaller EMac keyboard on that machine and last night, in an attempt to get the DVD drive open some of the F# buttons were pushed. This resulted in a hard boot from the power switch. Now both browsers blow up as soon as you try to do anything with them. I verified and repaired permission both from the HD and from the system disk and verified and repaired the disk as well but the problem still exists. I also unplugged and rebooted the ethernet router, but none of these steps have made any difference. What can I do now to fix teh situation?

I'm having a problem with my new intel iMac, 2.8GHz. Whenever I play games in XP through Boot Camp, especially Sim City 4, my mac crashes with the audio looping over and over. I have to hold the power button to restart my mac. I've been searching for solutions, but haven't found any definitive answers. I recently updated the Realtek Audio drivers, but that didn't help. Could there be heat issues when playing games on the windows side that causes this?

I have a 3.06Ghz 24in imac. Safari crashes a lot. Don't know what to do. I've reset Safari several times, and downloaded Safari 4 in order to uninstall and reinstall a new Safari 3. Safari version is 3.2.1. I've reset pram, restarted, and verified permissions several times over. Crashes happen almost exclusively when multiple windows are open. Other than that, I really am not sure of a pattern. Also, the restore tabs from last browsing session rare restores everything. I guess it's a buggy feature.

Got the computer a couple days ago and firefox has been crashing a lot. I cleared the history and cache but it still crashes. I did a quick search and it seems like a lot of people are having this issue and there's no solution for it. I was doing something very important and this has been pissing me off. If I don't find a fix I'm going to return this POS as the only web browser I like is Firefox. It's rarely ever given me any problems on windows based computers.

I just bought an iMac G4. This machine has been great, until a few hours ago. I was surfing Camino, when I went to go to IE for Mac (to check my Gmail, because Camino crashes when I go to Gmail) and then the same website I typed in on IE [URL] showed up in Camino. Of course, Camino crashed. Then, Camino started itself back up again, automatically surfed to [URL], and crashed again. Then Camino started up again...(and so on)
So I chose to force shut down the computer via the power button (which was probably a bad choice). When I got back on, I tried starting Camino. It crashed almost as soon as I clicked on it. I tried again...same thing. I soon came to realize that everything to do with the internet (Camino, Safari, IE, AIM) crashes the same way (almost as soon as you click on it). You ask how it crashed? Just the normal "This application unexpectedly quit" type.

Got myself a 27" iMac i7 which was delivered today.
Been playing with it all day in OSX and initially installed Win7 but I the display driver keep crashing and I was getting artifacts on screen then the message saying that it had recovered successfully.
Having read that Win7 was not fully supported I assumed that this was the problem so installed Vista, but got the same problem.
Screen stalled, then goes blank for a second and then the error message in the task bar.
I have just ran all the MS updates and also installed the latest GFX driver from ATI to see if that makes a difference.
I have also just ran 3dmark06 and that ran OK but I was expecting the fans to kick in at some point

Recently my 2-year old iMac (20inch (2Ghz, 320GB, 4GB RAM, OSX Leopard) has been crashing every day. The way to temporally "fix" the kernel panic is to restart the machine and boot into the instal disc, and run the disk utility (repair permissions, then repair disk). If I do not run the disk utility daily, the computer will begin crashing again over and over. Below you'll find the the crash data (which is always the same):
Interval Since Last Panic Report: 0 sec
Panics Since Last Report: 1
Anonymous UUID: A60F4F7D-F369-40E4-96F1-F2810273F105
BSD process name corresponding to current thread: kextd
Mac OS version:
9L31a
Kernel version:
Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_I386
System model name: iMac7,1 (Mac-F4238CC8)
System uptime in nanoseconds: 15150601001
unloaded kexts: (none)
I honesty don't know what to do to stop the crashing (other than runing disk utility every day). This is never happened before now.

I'm on a Mac OS X, version 10.6.3. Processor 2.66 Ghz Intel Core 2 Duo. Memory: 2 GB 800 MHz DDR2 SDRAM. I'm a graphic designer so I always have Photoshop CS4 & InDesign CS4 running simultaneously 8 hours a day. (Firefox 3.6.3 is also running). Never had a problem until recently - the screen would suddenly turn WHITE, or BLUE w/ VERTICAL STRIPES. Then I have to reboot.
I had 3 crashes today. I did notice when I was scrolling w/ my (sorta old & ghetto Kensington mouse) that it froze the iMac twice. IS THERE A PATCH, OR SOFTWARE UPDATE FOR THIS? Anyone else having similar crashes?

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.
