OS X Yosemite :: IMac Suddenly Shows White Screen After Update
Dec 8, 2014
The day after I installed the update(10.10.1) for Yosemite, regularly my iMac suddenly stops working by showing a white screen. After 10 seconds, the iMac reboots automatically and again shows a white screen. Than, it stops. No action. No noise. I'm always obliged to stop the iMac by pressing the start button and restarting by holding the 'shift' key otherwise I have to look at a white screen again! In the save modus, I can work(typing this story) and restart the iMac. After a while, the whole show starts again. What can I do? Installing Yosemite again and whiteout the update? Can I undo the update? This once, I made no backup before the update(Murphy's law).
i had the macbook Core 2 Duo for About 8 months and it was working great. yesterday i left a file download in firefox for 5 hours then went back to check on it , it was working FINE, Then i got Back after 2 minutes and the screen is suddenly white and not showing anything i shut down the laptop and restarted , there was a chime and just white screen...i connected the laptop to an external monitor AND EVERYTHING IS WORKING on the external screen but the laptop screen is white!
i was working on my macbook pro and suddenly the screen went white with lines through it. i tried a reboot and after the Apple icon shows screen goes white and does nothing.
i was on wireless so wen back and connected through wire and left over night in case it was heat
I am trying to get my MacBook LCD to work right. It happened because one time I was carefully wiping my MacBook screen with a little hand sanitizer and a paper towel. However, later my screen started to show a-lot of weird lines and eventually blue, pink and green tiny vertical lines but it is not completely renderd useless, it is just plain annoying and whenever I have an open window on the screen for a long time and I move it around eventually, it shows an imprint in the background into the screen and even when I restart, shutdown or use Windows in BootCamp it just shows up.

I got an old G4 and cleaned it up and hooked it up to a monitor, but when I start it- it shows the white startup screen and then just goes to black and i can't get an image on the monitor again. The computer is running and responding to the keyboard though
My MBP was working fine and then froze while I was on the internet. I turned it off and on again by holding down the power button. It powered on and froze on the white/gray screen with the Apple logo with the spinning wheel underneath it. I restarted it again by holding down the power button. Now it freezes on an all white/gray screen. I've tried starting it with the disk in it and holding down the "C" key and starting it and holding down the shift key after I hear the start up tone. Neither have worked.

i have a MacBook Pro..I had my track pad replaced recently..I am not sure if it has anything to do with my screen, however, the screen is randomly turning gray and white with lines and fading out..What does this mean
So my 20" 2.4 Imac crashed on me twice tonight. A box popped up telling me to hold down the restart button for several seconds to restat. The second time I did this it just sits with a white screen and give three loud beeps over and over. Is there a fix for this? Is it my ram? I'm at a loss.
My step mom has an iMac. The first gen intel one and the other day out of nowhere there was a white screen with a folder on it and now when you go to start up the iMac the screen just stays white.. What would be the cause of this and what should I do to fix it .. thank you
When I boot up my MacBook Pro (Unibody 17" 2011 model), it maks the CD noise, chimes the apple chime, then shows a grey/white screen. normally, this would progress to a grey screen with the apple logo on it, followed by the login screen, however in my case, the computer seems to just shut down. the fans keep running, so i know it isn't powering down completely. i can't change the volume/etc. after the computer has done this, so i'm assuming it isn't a display issue (also the display flashes white). does anybody know what this sequence of events is a symptom of? i'd really like to get my computer working again.
On my iMovie, mov video files doesn't work it shows up as a white screen also on my quicktime. But mpg files works prefectly on my imovie. Can someone help me find a codec or a mov a mpg converter for Mac OS X 10.3.9?
I have a 4-year old Mac and have noticed lately that it freezes up when I am using Safari. I'll be on a website and all of a sudden, it just freezes. The only way I can fix the problem is to manually turn off the computer and restart it again. Nothing works - unable to use the force quit command or the dock to close Safari. Why this might be happening, or if there's another way to deal with it when it happens besides turning off the computer?
I had been having the spinning cursor that wouldn't go away. A few days ago I updated my Macbook Pro 15 with updates. There was 8 all together. One was the multi update for lion. It would say that the file was corrupted during the dowload and try again. This was when i tried to download all 8 at one time. After a few times i noticed it was three files that wouldn't go through. So i downloaded each individually and the updates went fine. i used the computer for a day without any problems. Then when i tried to boot up the next day i got the spinning cursor again, it became hot and shut itself off. I then tried to boot again and now it just freezes on the white screen with the apple logo. Sometimes the logo will go away but stays on the screen.
I downloaded Mac OS X Snow Leopard on my desktop and computer restarted correctly. It then prompted me to update the printer software. There was an error. I continued and computer restarted and now the screen is white withe Apple emblem and circle continuously runs below. I have tried restarting the computer but this is the only screen that comes up.
My Macbook (2012) has been running incredibly slow since I updated to Yosemite. My apps keep crashing, including safari and chrome and I'm sending about 5 reports a day to Apple whenever they crash.
Chrome crashed while I was writing this - it happens routinely.
But my biggest concern is that when I restart my computer, the login screen looks like this:
It says "update needed" where it should have my name and image.
I've found a few solutions on here about turning off the firevault and trying to restart the computer again, but this image was taken on my restart try after made that change. I do know that it says I still have a mavericks update available. I'm not sure how that happened because I updated everything before I moved to Yosemite, but my apps store still says I have an update for Mavericks 10.9.5...

I received my new iMac on May 20. It is a 3.06 with an ATI card. I have not had much time to use it until this evening. I had been been setting up some bookmarks in Safari and then was working on a spreadsheet for about an hour when it suddenly shut down. The power strip in which it was plugged in still had it's light on. The iMac is the only item plugged into the strip. I then felt around the screen, the bottom section was cool but the top was rather warm.
The temperature in the air conditioned house is 71�F. Programs open at the time were Safari - which was on an idle screen as I had logged out of a site. Two sessions of Finder Entourage Excel - which I was actively using. Is this an over temp shutdown? I recall some people posting the temperature of their Macs. Are there any monitors on the iMac to see how hot it is running? There were no warnings that it was going to shut down.
Appstore automatically updated Safari to 8.0.2 this morning, but now I can't access the program. When I start Safari it takes a while to get going, a window opens for a moment with a spinning wheel and then the program crashes. I'm using a mid 2007 20" IMac (2GHz Intel Core 2 Duo processor with 4GB of memoryrunning Yosemite.
The system error report which gets sent to Apple makes no sense to me, as I don't have any technical knowledge, but scrolling through the report I found this section which refers to something crashing,.
I had Mavericks previously installed on my iMac mid 2007 and was promoted to upgrade to Yosemite which I did. Now when I try to open iPhoto and it reads unresponsive in red letters on the force quit window. When I select and click force quit computer then freezes. I am however able to open iTunes but when I plug my iPod in computer then freezes.
This is perplexing me: I've only had my iMac 21.5" for a week. I posted here about the white screen issue after the 1st s/w update. Now, on every restart I get the same *but only when* my USB ext HDD is plugged in; unplug it & it starts fine, plug HDD in and it mounts, checked external HDD with disk utility - AOK. Never had this problem with my old 20" iMac! It's still in DoA period so is it best to get it swapped out?
I ran software update and got (iPhoto, itunes, Security patch) so I ran it and downloaded everything except the Intel Security Patch. So I restarted and decided to try again. Restart didn't work as it got stuck and I had to reach around and restart by holding down the power button. When it came back up, I got the white screen with the grey apple logo and the spinning clock like icon..... spinning and that is where I am stuck, left it off all night and tried it in the morning, same thing.
I did try:
-resetting pram (nothing happened) -restart in safe mode, holding down shift key (nothing, stuck on screen)
I would try to start up from the OSX disk except I have a DVD in the machine. I am thinking it was that security update that didn't download fully that is doing this but how do I get the imac, "unstuck"? or how do I manually eject that DVD to put in a OSX start up disk?
Three times in the last week or so my iMac's screen has just turned white (once with almost a ribbed pattern with thin grey vertical stripes evenly interspersed) and become completely unresponsive, with the only option being a hard reset. It's happened under a variety of conditions: while surfing in Safari, while working in Aperture, and once without doing anything (I was on the phone sitting by my computer). Each time I've restarted it everything seems to work fine for a couple days, but then it happens again. I've never seen anything like this and I figured after the third time it's time to ask for help. Does anyone have any ideas?
