Jun 24, 2014

My MacBook Pro 2010 15 inch screen shuts off randomly. The whole laptop doesn't shut off just the screen. It calls it a panic but I have to hold down the power button to shut it off when this happens or it will stay on the black screen.

IMac :: Screen Saver Only Run For A Few Seconds?

Feb 10, 2010

My screen savers (any of them) only run for a couple of seconds before returning me to the desktop or any applications running before I turn it on.

I've set the top right corner of my screen (expose') to be the Hot Corner for turning on the screen saver.
That works normally, but it just keeps on turning off shortly after =[

Testing the screen savers in System Preferences make it work but I really don't want to go all the way in there every time to turn it on...

I don't know what's wrong.

##UPDATE## I've found the answer to my problem. It lies in an app called Caffeine. I can either click it so it shows an empty cup or update the app to a more friendly version to my OSX and quit it.

I hope this can help anyone in trouble because this is a really understated issue (at least with Snow Leopard! since it has compatibility problems with the old Caffeine app).

OS X V10.7 Lion :: Screen Saver Freezes When Waking

Mar 17, 2012

After waking up my computer from sleep I find that the screen saver always locks/freezes and becomes pixelated. I move my mouse around and it sort of "erases" the saver to reveal the login page underneath. This happens on my new iMac (2011) and now is starting to happen on my MacBook Air.

MacBook :: Screen Color Settings Change After Screen Saver?

May 8, 2009

so this has happened twice now in the past month, my mb is in screen saver mode and i wake it up to find that the color is off in the screen. meaning that the color settings changed and the screen has a swashed out blue tint to it. first time i restarted and all was good, second time i clicked on the preferences icon and then the screen went back to its normal setting. my normal setting is not the factory one but one of the ones that people said makes the screen look better.

so what gives, is the integrated chip dieing on me?

MacBook Pro :: Screen Is Black Does Not Want To Exit Screen Saver Mode?

Jun 2, 2012

When my MacBook Pro 13" i5 goes into screen saver mode, which is black, it won't return to normal mode. Tried all keys, trac pad, closing the lip and re-opening it,  and it won't respond. The only thing that works is holding down power button for hard shutdown, then restarting it. It has happened 8 times in the last 2 weeks.

OS X V10.7 Lion :: How To Turn Off Using Photo Library In Screen Saver

Mar 28, 2012

Is there anyway to turn off screen saver (and desktop) in using my photo library (Aperture)?  Currently it is using my entire photo library as screen saver and I wanted to turn it off.  Clicking on the "-" button in the Screen Saver preference pane does not remove Aperture photo library from the list.  I had OS 10.7.3 installed.

OS X :: Monitor Wake Up With Screen Saver Image On Screen

Jul 15, 2010

I have a Quad Core Mac Pro running Snow Leopard 10.6.4. I've been having this issue for the past couple of weeks. Basically I have my monitor set to turn off after after 15 minutes of inactivity, my Mac Pro is always on. After 5 minutes of inactivity my screensaver comes on and stays on until my monitor turns off. When I move my mouse to wake my monitor, sometimes an image from the screensaver appears onscreen for a few seconds and then disappears when my desktop appears.

I have repaired Permissions, rebuilt my drive using Disk Warrior, installed the 10.6.4 Combo update but the issue remains. An image from the screensaver doesn't always appear when I turn on my monitor, this issue is sort of random. Usually my desktop appears right away with no static image from the screensaver.

IMac :: Suddenly Shuts Down - Screen Warm

May 25, 2009

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.

I have a mac mini intel and I was in the middle of working with my blogs, then there was an annoying spinning wheel of death, so normally, I would hold the power button for few button to restart and I did. then when the desktop was loading, everything was back to the "new" desktop with alot of stuffs missing, so I restarted it again using the apple menu, then the startup screen took so long and out of nowhere, it shutted down by itself. I tried to power it on again and again, unplugged the cords, still didn't work.

IMac (Intel) :: Shuts Down During Load Up Screen

Aug 24, 2014

I just got home and I realized the power was out. I bought this iMac literally like two months ago (I actually bought one two months ago but it wouldn't even turn on so they gave me a new one) It was working perfectly fine, and I was writing a report. I left the computer on and left the house only to return hours later with the power out, and when I turn it on it shows the start up screen with the Apple Logo, the little progress circle, and a progress bar that fills up to the end everytime but once it fills up to the end it stays there for a few minutes then the computer shuts off.

OS X V10.7 Lion :: Why Does Screen Saver Prompt For Secure Disk Image Password

Mar 17, 2012

I go into System Preferences->Dektop & Screen Saver.  As the program "loads" availabe image sources and such I get a pop-up requesting a password to my secure disk image. Yes, I have a secure disk image in my home directory. Yes, the secure disk image is currently "locked" (Not mounted in finder). 

I click cancel (a few times, probably 2 maybe 3 times) and things continue along fine. I select a photo source that I want for a screen save and exit peferences. I then go an start the screen saver (I'm using Hot-Corners). I get the message "Looking for pictures....." for , well...basically forever... 

Sure enough I touch the mouse to leave my screen saver and there is the pop-up again.  Asking for me to unlock my secure disk image. 

I thought this might be related to Spotlight.  I tried reading several threads and have gone as far as taking my entire hard-drive/volume and putting it into the "Privacy" tab under spotlight. 

how I might get it so the "Desktop & Screen Saver" stop prompting me to unlock my secure disk image?  (WITHOUT having to make sure the disk image is unlocked before I sleep my screen or open the screen saver utlity) As always, I am only speculating that this is Spotlight related so that could be a red-herring....

IMac :: New 21.5 Inch ... Getting Random Black Screen

Sep 24, 2010

The screen randomly turns black without any major reasons. It doesn't seem to be a sleep mode/screen saver thing as the music continues to play on. I can adjust the volume or pause the music with the keyboard but the screen just won't turn back on. I have to shut it down using the power button and it happened several time the last couple days. Anyone else experience the same thing and got a solution?

PowerPC :: Screen Repair - 20 Inch Imac G5?

May 21, 2009

My lovely cat recently decided to walk around my desk while I was at work and knocked over my Imac, causing a large crack in the glass and the screen. I'm not technically capable enough to do the install of the screen/glass myself, but I was wondering what I should expect a repair from an Apple certified technician to run.

IMac :: 27-inch - Dust Under The Screen - How To Clean

Jul 17, 2010

A few months ago, i noticed what looked like a streak across the screen, but it wasnt on the outside, it was on the under side of the glass. Now, the streak is very visible esp in natural lighting. Its not noticable at night, because the screen light shines through it making it invisible.

It looks like dust? But im not 100% sure, but it has a directional pattern which leads me to believe its being causes by the inner fans of the system, and that there are some gaps where the air flow is constant. Also, the streak is in the upper left hand corner mostly (no where on the bottom poritions). Im assuming that the place holder at the top-backside of the iMac, for the exhaust fans to expell the heat from within, is what is causing this air flow.

IMac (Intel) :: 27 Inch - Screen Randomly Goes Off?

Jun 2, 2014

I have a 27" iMac. Just recently, the screen has begun to randomly shut off. I then have to squeeze the power button, followed by a click of the mouse. This will bring me back to my password screen. Sometimes, that would be it, other times, it will do it repeatedly, for no reason, and then settle down. 

Just for those of you who are bound to ask me about my Energy saving settings: Computer to sleep – Never. Display to sleep – 15 min. 

It seems to me that this could be a hardware issue, but just incase any of you have had any experience of something similar, I thought I would ask.

PowerPC :: IBook Screen Backlights Shuts Off / When Screen Is Tilted Back Farther Than 45 Degrees

Ever since I sold it here on MR and got it back, there has been a problem with my 12" Dual USB iBook G3 500MHz's screen (lord, that's a long name). Whenever the screen is tilted back farther than 45 degrees or so, the backlight shuts off. I can open the casing and fix it if it's possible. Does anyone know what the problem with it is? I'm trying to get it fixed up and ready to sell back to my friend as his first Mac, and I'm trying to get every problem resolved

IMac :: Have An Inch Wide White Stripe On My Screen?

Jun 11, 2008

I have an inch wide white stripe that runs from the top to the bottom of my screen. This is on an Imac. The cursor disappears when going through it but pops out on the other side. It doesn't move but I can drag my window back and forth to view the part the stripe covers.

Any ideas or should I locate a local mac repair person?
