My Mac will freeze at random moments (not while running any particular app or program) and go to a blue screen, after a few seconds it clears up by itself. Sometimes it will happen several times in a row, sometimes 10 - 15 minutes in between.
View 1 RepliesAt least, it seemingly randomly turns off. I can be surfing the web or whatever like normal, but then after a period of time the monitor goes black. I can see that the computer hasn't shut off, but it's as though the computer is on its lowest brightness setting. It can be temporarily fixed some times if I lower the brightness all the way via F1, then put it back up, but if it goes up more than 3 or 4 boxes it goes black again.
It also goes black if I were to move the monitor any time during this whole thing. I've heard things like an inverter cable and board, but I have no idea what's going to fix this. This is my only computer, I use it for all my school work, if it breaks permanently I'm screwed.
Anyone else noticing their new macbook air freezing randomly and the screen just turns completely black? The back light is still on but nothing is on the screen.
None of the buttons work, can't force quit anything, i have to hold power button to turn it off then back on.
It has happened to me twice already, first time when i was installing the adobe suite, second time is when I was working on a school assignment with a simulation app (not cpu or memory intensive AT ALL).

I have a 3.06 GHz, 4 GB, iMac running 10.6.1. and I have a weird problem: while I was running Windows 7 under Boot Camp, during a simple task, my screen suddenly turned a solid shade of gray. Having no other option, I held the power button, turned off the computer, and turned it back on.
When I booted back to OS X, it happened again immediately upon opening iTunes. This time the color was solid black. Concerned, I turned off the computer, waited a moment and booted it back up in Safe Mode, where I currently have no problems whatsoever. From Safe Mode I repaired my disk permissions, cleared my caches, and zapped the PRAM while restarting my computer back into normal mode. Unfortunately the problem persists, this time my screen turning a solid shade of dark purple.
I'm going to call Apple Care in the morning, but has anyone heard of an issue like this? I searched the forums for a solution, but wasn't sure what terms to search for.
The first time I connected to my HDTV using a mini displayport-dvi and a dvi-hdmi adapter, it worked flawlessly. Stupidly, I set my TV to a resolution it couldn't support. Now the screen only turns blue until System Preferences eventually crashes and the TV gets no signal.
I've tried clearing my PRAM, deleting the profile in the colorsync folder, and even deleting /Library/Preferences/com.apple.windowserver.plist out of desperation. I've confirmed that it's not a problem with the adapters by successfully getting another HDTV to work. Where could could OS X be storing the display's settings?
I recently had my screen replaced because of a crack. Now I find when I open the laptop to use, after being on sleep mode. It momentarily turns blue, sort of flashes/glitches then works normally. Should I be concerned?

View 24 Replies View RelatedI got a new Macbook Pro Retina (mid-2014) a few weeks ago and the trackpad and screen randomly freeze even when the only thing I have open is Safari. In other words, it doesn't feel like my computer has a 2.6 GHz Processor and 8 GB 1600 Mhz Memory. My downloads folder also constantly has the loading bar under it; it goes away when I remove it from the dock and replace it, but appears again after downloading one thing.
This is really frustrating when I got a new Macbook so that I wouldn't have to deal with these types of problems. They're all issues that I never encountered with my Macbook Air (mid-2011).

Today my imac done something wierd. When powering on it got to the blue screen before the password login and it just froze on the blue screen. I done a hard restart and rebooted a few times. Didn't do it any more after that.
Should I be worried? It's only a few months old.
I've been reading the other post and searching for ways to fix this. My ibook froze a couple of days ago, so I pressed the power button to do a hard turn off and then restarted it. It hasn't made through the blue screen since. It seems to load all way and then stops at the end, but stays on the blue screen. The mouse is not frozen though, I noticed that was a problem for some people. So I've already tried a lot of the suggestions I could find. I've tried resetting the PMU,Start your computer holding the ⌘ and S key on your keyboard. When the black screen turns up and the "writing" stops, you will see something like
View 1 Replies View RelatedI have an ibook g4. It freezes at the blue screen with the apply on it. The little circle goes around and around but nothing happens. I took it to an apple technician yesterday who told me the hard drive is toast so I should just throw it away. (Actually, he offered to take the keyboard.) When you do the fsck -fy it says that the hard drive was repaired sucessfully. Is it possible to have a hard drive that is bad and a message which says it has been repaired successfully? I don't mind having the hard drive replaced if that is what is wrong. I do not have any of the install discs any longer.
View 2 Replies View RelatedI am a Mac-newbie who recently switched from PC to Mac. I know a little about comps and have some experience with Windows and Linux. Now the Mac. I upgraded my iMac 20" (bought it used from a friend) from Mac OS X 10.4 to Mac OS X 10.5 and everything seemed to go according to plan until it came to the re-boot and the comp froze on the blue screen with the movable mouse pointer showing. I tried the apple key with s on boot and did fsck -fy and fsck -f a couple of times. It only shows "The volume MacC appears to be okay". Everytime I typed "exit" to go to the log-in window it still gets stuck on the blue screen. I tried to start it with the installation disk in the DVD drive but now it doesn't eject it either anymore. So, the situation is: I have an iMac with that wont go past the blue screen, with a workable mouse pointer and a stuck DVD in the drive. I am extremely frustrated especially since I do not have a second Mac to read the HD in the iMAc with and I don't have a backup system (except my PC Laptop). What can I do?
View 1 Replies View RelatedOn my 1st Gen Mac Pro, I suddenly get a strange blue screen out of no where. Everything on the screen freezes for a few seconds then the screen flashes blue for another few seconds. After the screen comes back from the blue, everything works perfectly again. Even when listening to music, music pauses for a few seconds and then comes back. This happens a couple times a week and its getting on my nerves. Sometimes it lasts for a long time and requires a hard restart.
I have tried reinstalling Leopard/tried hardware test/upgraded to the 8800GT video card and the 3870/I cleaned the whole inside of the box with compressed air. I even took her into the apple store and had a genius look at it over night. They told me everything is working perfectly. Ofcourse it started doing it again after I got home with it. The apple store suggested that I could always replace the logic board but they want over $1000.00 for that and I dont know if its worth it.
I was using my Mac (Macbook Pro 15" screen) and tried opening a file in GarageBand, at which point a warning message came up saying something about a midi file and something not being allowed, and then froze, resulting in me having to switch the computer off from the power button and restarting (Sadly I didnt realise that this would be the start of a whole host of problems and didnt make a note of the warning message). After rebooting I got the 'stuck on the blue screen with the Apple logo and infinitly spinning wheel' problem that i've seen in a few posts. having tried numerous suggestions posted with no change I ended up taking it to the genius section of an Apple store. When i got it back they said that it may have been a corrupted file, and that they re-installed and reset the starting programs (Something along those lines, I cant quite remember). I can now get onto the computer and use it, though some new problems have arisen.......

This is a strange issue I have had with my Macbook Pro for a while now. Whenever I am in a situation where I am only using my computer for say, listening to music purposes, I like to turn the brightness all the way down. Whenever I turn the brightness all the way down, however, after a few minutes it will go back up 1 pip of brightness on its own. Once I come into contact with the trackpad, however, it goes back down. Then it will go back up 1 pip on it's own again, and go back down when I touch the trackpad. It continues to do this and it's quite annoying.

If I am using "Mail" and then click on the Apple logo (top left) the Apple turns Blue and I cannot open anything from it. Is this correct ?
View 2 Replies View RelatedSo, okay, I happen to have an 13-inch MacBook (aluminum). Before I move on to point out all the problems I'm having, I guess I should point out I bought it from BestBuy, and open box. Don't worry, no need to scold me, I've learned my lesson.
What happens with it is that it freezes at random. Completely. It doesn't do a thing. I can't move the mouse, and nothing on the screen moves. This forces me to do a hard reboot. Sometimes, when that happens, when I turn the computer back on, airport doesn't appear. I check on networks, and it won't turn itself on. I have to turn off the computer and turn it back on until it decides to appear.
Apart from that, there are times where Airport randomly decides to shut itself off. At the top, I can see the Airport icon but the signal lines are gone. It's completely blank, as if I had turned it off. If I try to turn it back on, it doesn't do it. I click to turn it back on and it doesn't do anything.
I took it to BestBuy since I have a warranty with them. First time, they said my harddrive was faulty and they'd replace it with no cost. Fair enough. When I picked it up a week and a half later, the problem was still there! I left it at BestBuy again, and the guy told me that he can't find a problem with it. That he had run all the tests and that my computer passed them all without a problem. He checked everything, and yet the problem is still there.
while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.
I purchased a new late 2013 27 inch iMac 3.4Ghz i5. The only thing I did after pulling it out of the box was restore Time Machine from my previous iMac. On startup the machine boots as expected, but gets interrupted by the screen turning a dark blue, and the apple logo turning bright red, for about a second or so, then boots as normal, and opens Mavericks. I've spoken to Applecare - they suggested I re-install Mavericks, which I did. The problem is still there. I've done a hardware diagnostics test - no problems. Though I wonder if it could be a faulty graphics card? As far as I'm aware there are no other issues with the iMac. The machine is under warranty but would love to solve this if possible.

View 7 Replies View RelatedMy iMac randomly freezes and crashes on me. Most of the freezes occur when scrolling with my trackpad on websites with Google Chrome. I get the pinwheel and have to use the power button to turn off and on the iMac. I haven't noticed any particular connection to Flash websites or video related sites. It just seems kind of random. I've also been careful to have absolutely nothing else running and it still does not prevent it.
Also, from time to time the iMac will crash and go to a solid color screen. Either Blue-Gray, White or Black. It seems to be random colors. When this happens, I have to use the power button to cycle it off and back on again.

I have got a problem with my brand new Mac Pro. It randomly freezes at start-up and shutdown. I sometimes am able to work around the problem by turning on the monitors last or switching them off first but it does not always work and is a pain anyway. While waiting for Apple or another manufacturer to release a decently priced 4k display, I am using 2 HP 24' monitors inherited from my previous desktop.
One is connected via an HDMI cable (HP2405) and the other via a thunderbolt to HDMI cable with a DVI adapter (HP2448).Would I be better of using a Thunderbolt connection for both displays ? Or any other connection?
I used to open up GarageBand 09 normally and it would take about 10-20 seconds. Now it takes a couple of minutes while it says its not responding. I don't think this is normal. Also sometimes when I am scrolling down through software instruments it randomly freezes and then shuts down unexpectedly. I have the new 13.3" 2.4ghz macbook. i have alot of free space and no files in the GB folder. I haven't touched anything regarding the system's font, new or old.
View 2 Replies View RelatedI'm having huge issues with my 20-inch early 2008 iMac running 10.7.3. I upgraded my RAM (to 4Gb) 8 months ago and everything was running nice and easy until I upgraded to Lion. Either one of these things happen: My screen goes entirely grey or blue with white faded thin vertical stripes at random timesMac freezes working with any Adobe applications (mouse cursor still works but I can't click anything until I turn off and on)Mac freezes for a while and after a 30-second delay clicking and pressing buttons frantically everything goes back to normal
The strangest thing is that when I play Sims 3 for example (a beast of RAM and video drainer) nothing happens. I tried almost everything from repairing permissions to re-install my memory modules. I couldn't run the hardware test.
Note: I live in Brazil so sending my machine to a Genius Bar is completely off the question.

Only a laserprinter is connected. Sometimes I can work for a few weeks without problem, but then the computer freezes. The computer sounds 3 monotone chimes in a row and repeats this, keyboard an mouse become inactive till I do a hard shutdown.Took the computer 2 times to the Apple store, they tested for a week but apparently nothing happened then.
