Dark Display after boot and wake up

Hello,
I have seen some similar posts to what might be the same problem.
When I boot up my Mac and it gets to the desktop the screen is dark. I can barely make out the desktop. I have to either restart or completely power down and restart the system.
I have noticed that this happens when the Mac wakes up from a long nap.
So far it looks like this happens when applications are open.
Since I am using mine for business my e-mail is always open.
Sometimes Daylite is open and Acrobat 8.
This is happening more frequently now, and I have updated to 10.5.3.
Any suggestions?

First, check out the related support topic called: MacBook Pro Blank Screen (Built - in & External).
This problem is an epidemic now. My year-old MBP is now on its third logic board in two months, and the problems continue.
The display just refuses to wake from sleep, and has only intermittently been fixable (without a motherboard replacement). As posted here, I have rebooted, rebooted from the install DVD, rebooted from an external disk, tried plugging the computer into numerous external monitors, zapped the PRAM (w and w/o the battery), removed the battery and power adaptor for a while, etc. The worst thing about this is that it sometimes comes back.
The computer was flawless for its first 8 months, and then in June 2008, all ** broke loose. I always update the computer with all new installs as they are offered, and my previous 11 Macs (including 3 laptops) never had a glitch. After the last full motherboard replacement, I have had the screen fraz with random patterns and then the computer lock-up and even shut down automatically.
All I can say is thank god for Time Machine. I just plug in my back-up disk and all of my recent changes get sucked onto it, automatically, without me even seeing the screen. Then I just plug my back-up drive into the desktop and I can retreive what I desperately need. Not a solution, but a significant mitigation of an otherwise dire situation.
Finally, I do not want to even think about my iTunes DRM permissions. I have not updated them to each new motherboard, as I'd quickly run out of my 5 license "locations." So, half of my collection is currently unplayable.

2012 iMac 27" fails to boot AND wake from sleep

Hi all,
My 2012 iMac has recently started giving my trouble when booting and waking from sleep.
When booting - A normal power up results in the apple logo screen being stuck, then I have to hold down the power button for a few seconds until power off, then i power it back up and the computer boots up normally. NOTE: only at the second time does the computer succeed in getting past the apple logo screen to the sign in screen.
Waking from Sleep - When ever the mac goes to sleep he doesn’t seem to be able to wake up. Usually stuck on a black screen with just the spinning wheel shown. At times i waited more then an hour to see if he can get passed the black screen but in vain.
Other then that the mac works fine.
Both issues started roughly two weeks ago and roughly at the same time.
My mac is mostly used for work, I'm familiar with computers so I am trying to be extra careful with installing weird applications but you could never know..
SPEC:
Late 2012 iMac 27'' - 3.4 Ghz i7.
16GB RAM.
1TB Fusion drive.
2GB NVIDIA GTX 680MX
Wired keyboard and a Magic mouse.
Mountain Lion 10.8.5 (Updated and backed up on a regular basis)
Things I've tried:
Boot to Recovery and Repair Disk/Permissions.
Safe Boot.
SMC reset.
PRAM reset.
* The first two produced a single case of a normal start up, but after a shut down the problem remains.
Any ideas/thoughts/help would be much appriciated,
Thanks in advance,
Idan.

ITunes can't connect to Apple TV sometimes after sleep and wake up

Hi!
There are any issues to find in the discussions depending on problems between the ATV and iTunes but no solution helps me to solve the following problem till now.
I am using a Mac mini (middle 2011) as a central storage for multimedia data. The exact description of the network can you find further down.
The problem is that iTunes sometimes can't connect to the Apple Tv via Airplay. There is a window open what tells me that iTunes try to connect to ATV. But it doesn't work.
After determine iTunes completely (normal closing doesn't work because of that open window) and restart it, it will work probably.
Itunes is connecting to ATV via Airplay immediately.
Sometimes it works for any days with a view sleep and wake up procedures. Sometimes the problem appears while I'm listen to music after any minutes of starting.
I send the mini and the ATV to sleep with the remote of the ATV or let it go to sleep alone. To wake up ATV and mini I push a button on the remote.
Following components are working in my network:
- router FritzBox 7390 from AVM (2,4 and 5 GhZ at the same time)
- Mac mini (middle 2011) connected via Wlan
- two Airport Express with connected loudspeakers in various rooms (Wlan)
- Apple TV (third generation) connected with home cinema via HDMI and with the network via Wlan
- Telekom entertain setbox for TV connected via LAN over Wlan bridge
I have tried to use the whole system with an Airport Extrem as router for wlan but the problem was the same.
I suppose it could be a problem with DHCP Lease or the Bonjour? What can I do?
Last but not least...the devices have installed the newest firmware or software versions.
Thanks a lot for support!

i bit the bullet and re-associated library on ATV. On atv, setting/computers; current library was grayed out, clicking creates a warning that all media on ATV will be lost, it takes its time to earase the disk, then an option to connect to itunes becomes available just like fresh setup. ATV produced a code to enter into itunes. itunes complained that it cannot communicate on port 3689; googleupdate.exe was using this port; disabled googleupdate; rebooted everything for good measure. so now i'm waiting for 100GB of home movies and music to sync to ATV (thanks apple!). one thing that got me stumbled - when ATV showed up, there were not tabs for music, movies, podcast, etc, only settings and photos; solution: deselect 'automatic sync' by selecting 'custom sync' in the settings tab.

HT3964 my computer displays only a blue light on the screen after booting (and rebooting)! How can I fix this?

There is a blue light on the screen of my mac book pro and the computer will not display anything! Does anyone have any advice/recommendations!?

For Safari you could try clearing its cache and history via Settings > Safari.
For Safari and your other apps you could close them all completely and then see if they work when you re-open them : from the home screen (i.e. not with any app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of each app to close them, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Macbook Pro can't reconnect after sleep and wake-up

I didn't experience any kind of problem until now, but a few days ago when opening the lid on the Macbook it would fail to reconnect to the network.
I am getting the "auto-assigned IP" message and I need to turn the Airport OFF and then back ON again for it to connect properly.

I tried restarting the machine a couple of times but it did not work. Otherwise I didn't seem to lose connectivity while connected/streaming/downloading and I hope this won't start happening.
I'd like to know if this is a hardware problem. My Mac is still under warranty, so in theory Apple should replace a faulty Airport.
I also got an iMac with 10.5 on it and a crappy Windows laptop that seem not to experience any issues. I could also connect to the network without trouble with my Android smartphone and some friends' laptops. It's just the Macbook that has problems.
Thank you.

You need to charge the computer, perhaps the battery went dead.
Do a SMC and PRAM reset, see if that assists.
Also hold the shift key after that upon boot, that will fix things
https://discussions.apple.com/docs/DOC-3046
If you get into your account, see if system preferences opens and try to set the time and date, align with Apple's servers, reset the screen saver and desktop picture see if it holds upon a reboot
If not your going to have to delete your
com.systempreferences.plist
file in your
"User"/Library/Preference folder
Reboot the machine and then open System Preferences and reset your preferences.
Now in 10.6, the "User"/Library/Preference folder is not hidden
In 10.7 the "Users"/Library/Preferences folder IS hidden
so in 10.7 you need to use the Finder > Go To Folder and type
/Library/Preferences
and click OK
Then scoll down to the file above, there will be two of them perhaps, one is a lock file the other one you can Trash, so do that and reboot.

Blank Screens After Startup and Wake From Sleep

About half the time I startup my Mac Pro or wake it up from sleep, the screen will go blank, usually about 20-30 seconds after video appears on the screen. The system seems to be running, you just can't see anything.
I have had the screen go completely white, black or blue and occasionally, there will be a solid color with vertical lines throughout the screen. The only thing that will get display back is a forced restart of the entire computer.
I've zapped PRAM and run run hardware test with no issues reported but the problem keeps coming back.
I'm driving a Dell 2407 on my ATI 1900XT. Dell supplied a single-link DVI cable, could that cause issues with a dual-link port on the video card?
Mac Pro Mac OS X (10.4.9) ATI 1900XT, 2GB RAM

Intel Macs, especially MacBook Pros seem to be notorious for sleep issues...either not sleeping when supposed to, or not waking up from sleep properly.
My MacBook Pro has come out of the brief case hot as heck with a dead battery often enough, even with all the updates appled. If you listen to the MacBreak Weekly podcast, that's a common complaint of Merlin Mann, who can't figure it out with his machine, and he's no dummy when it comes to Macs. Not very encouraging, is it?
Still, what I would try is reinstalling the OS X 10.4.9 update. I've often read/heard on podcasts that it's better to manually install the larger Combo version of the updates. That seems to have fixed problems for me in the past.
Get the Intel 10.4.9 Combo Update here: http://www.apple.com/support/downloads/macosx1049comboupdateintel.html
Good luck.

Macbook Pro No Longer Recognizes Primary Display After Boot Camp/Linux Installation

Hey All,
So my old 15" early 2006 Macbook Pro (1,1) no loger recognizes the primary display. I can use an external monitor just fine, but when I go into System Profiler, it's like my primary display disappeared. I reinstalled Snow Leopard, reset PRAM, NVRAM, repaired my permissions, tried to update my mac, but litterally nothing I have tried has worked.
It started when I tried to install both Windows 7 and Ubuntu. After completing the Windows 7 installation, I restarted my computer and it just hung on the Apple logo. I could feel the fans begining to spin really fast and it felt like my laptop was on fire. I restarted my computer, let it cool down, and it hung at the Apple logo again. I rebooted it a final time, and nothing. Black screen. No backlight or image...nothing.
Is this a hardware or software issue? Did a software issue cause my screen to overheat and just die?

Hi,
it seems we are both suffering from the same problem. I described mine in https://discussions.apple.com/thread/4299194
Did you get your problem solved? If so, can you tell me how?
Thank you in advance!

Display repeatedly sleeps and wakes - Geforce FX 5200 DVI

Hi There
I own a G4 powermac Quicksilver (733MHz) 10.4.11.
For a long time I have been using an old mitsubishi 17" monitor alongside my powermacs standard 32mb VGA graphics card.
Recently I decided to buy a 20" Apple Cinema Display and a new Nvidia GeForce FX5200 256mb (DVI and VGA) graphics card which would apparently work with my g4 and the display.
I installed the graphics card firstly using it with my VGA monitor and everything appeared to work fine. I later tried it with my new apple display and everything was working at first but after about a minute of being on the display started repeatedly sleeping and waking constantly.
Now this is all that happens when I turn on my g4.
I thought it could possibly be a driver issue but I don't no were to look?
Does anyone have any ideas what I could do?
Thanks
Freddie

Yes, I am sure it's the same hardware (unless someone snuck into my office and made a switch) Musta been a full moon or something but at least I have a witness.
So what would be the cheapest VC upgrade that would permanantly reinstate the rotation.
Thanks for your imput

I'm confused
I took this to mean that your DID have an install disk.
By holding down the "C" key, you are booting to the install CD.
Alternatively, you can hold down the "option" key, to select which drive to which you want to boot.

Scrambled display after boot issues?

This afternoon, Netscape crashed on me, and I decided to reboot the computer. It refused to boot-hung on the initial screen, with the grey background and Apple logo with no 'loading' indicator. I gave it about half an hour, since it sometimes hangs there for a minute or so. After two more restarts, got it to boot off the Hardware disk. That didn't find any issues, but it still wouldn't boot off the hard drive; I couldn't find my 10.3 disk OR my Norton disk, so I booted off a 10.2 disk long enough to access Disk Utility. It found a few permission errors, which it fixed, but nothing else. It did boot after that, but the screen is totally scrambled. The cursor appears to be in the top left corner and not moving, but the Invisible Mouse is moving around the screen and usually works-if you can figure out where it is to click on something. The background wallpaper is garbled; if you draw 'mouse boxes' it cleans up, unless you cross an icon, in which case the entire screen rescrambles. Any open window or menu throws distorted (stretched, squashed, almost anything) doppelgangers around the screen. Dropdown menus appear fairly normal by themselves. Windows will have lines of pixels appear and random portions go blank. We have the Dock set to disappear when the mouse isn't over it; when it pops up, the menu bar vanishes. Makes me sick to my stomach after a few minutes! As best I can tell, under all the visual garbage, everything seems to be functioning normally now. It is an unmodified G4 800 mHz with 256 mb of RAM. Any ideas??

Sounds like mine exactly!! I have been trying all weekend for some kind of resolution, and trying is very, very trying I have reset the PRAM (many times), used Apple + S and fsck -y, done disk repair using the disk utility on both Norton Systemworks and Mac OS X. I have also repaired permissions using the latter. All to no avail.
Over the weekend I have reinstalled the original software (using Archive & Install) which has necessitated hours and hours of updating and reinstalling other software (printer, Palm, Expressit, iLife '06, broadband, and Norton sytemworks, ...). Things seemed to be OK until the Norton installation when the problem began again, though to a lesser degree than before.
Meanwhile, I had posted a message on another forum (www.macassist.co.uk) and got the following reply:
"What Mac do you have and what OS is running?
If you have Mac OS X then your problem is Norton Disk Utility it wreaks havoc on Mac OS X and should be trashed."
Good news I thought, and did as suggested, uninstalling Norton Disk Utility. All seemed well at first, but last evening the problem began to reassert itself, and this morning I was unable to boot up without full scrambling. I again reset the PRAM, to no avail, and finally rebooted with Apple + S, and fsck -y. Although the latter reported no repairs, the computer did reboot OK and enable me to enter this discussion.
I have taken photos of the screen in its variouse stages of degeneration in case of need.
What shall we do next??????

Macbook Pro won't finish loading after boot and password

Right after I installed McAfee Virus Scanner for Mac and restarted my laptop it won't load all the way after I put in my pasword. It's stuck on the space screen that comes pre-installed, right before my desktop appears. I went into safe mode and dragged the new application into the trash and did the disk utitlity. It finished an it says the disk is ok. The battery is charged. Is there something else I need to fix? What is going on?

You have a hardware failure. Could be the drive itself or as has happened on a lot of 2009 model MBPs the cable that goes from the drive to the logic board has failed.
For either you will be better off taking it into an Apple G Bar and having it looked at. Note to the Apple staff that it may be the cable and not the drive.
If you are in the mood to test it yourself then remove the drive from inside the case and connect it to the system with a SATA to USB adapter and at stratup hold down the Option key and select the USB connected drive as the Boot Source. If the system boots off the drive then it is the cable. If it doesn't boot off the drive or the drive isn't even listed as a boot source then the drive has failed. Whichever one it is, Replace that part.

Gray screen after boot and blue screen with stripes

Hi, I have a MacBook Pro Mid 2011 with Mavericks (came with Snow Leopard).
History:
One day i was working and things were too slow. I tried to restart but it was taking too long to close all the programs. So I forced shut down by holding the power button. When I turned it on again, my problems begin.
Problem:
The Apple logo and the spinning wheel appear. After a while, both disappear and it freezes at gray screen. Some solutions I tried make the screen goes blue with black vertical stripes. In both cases, I have to force shut down.
Solutions I tried:
- Reset NVRAM
     It does reset, but nothing change
- Log in my Windows partition. I can't log
- Hold option key and choose recovery. Blue screen
- Recovery system by restart and press Command-R. Blue Screen.
- Safe boot by pressing Shift. Blue Screen
- Verbose by pressing Command-V. Restart and gray screen again.
- Single-user mode by pressing Command-S
     Tried to reapair hard drive:
          /sbin/fsck –fy
     Returns the message "** The volume Macintosh HD appears to be OK.". I restart and nothing change.
     Tried to change startup permissions:
          mount -uw /
          chown root /
          chmod 1775 /
          exit
     Restart and nothing change.
- Boot from a bootable USB flash drive
     Holding option key, I choose my flash drive with Ubuntu installed. It gives me 3 options: Use Ubuntu without installing, Install Ubuntu, Repair Disk      Errors (something like that). The 3 options go to the blue screen
     Flash drive with Mavericks. Blue screen.
-Boot from my Snow Leopard CD. Gray screen, restarting, gray screen.
I don't what else I can do. Is it a hardware problem? At first I thought it was some corrupted file. But is it a GPU or logic board problem? What else can I try?

I found this to work at least to get in and backup some files. It is VERY important to put these commands in EXACTLY as seen here, including spaces.
Boot into Single-User mode (Command-S while booting up)
Execute the following commands:
/sbin/fsck -fy /
/sbin/mount -uw /
mkdir /Disabled_System_Library_Extensions
cd /Disabled_System_Library_Extensions
mv /System/Library/Extensions/ATI* .
mv /System/Library/Extensions/AMD* .
touch /System/Library/Extensions
exit
I guess these two graphics extensions go bad quite often on Macbook Pro 15-inch. They are part of the logic board. The only problem I had was I still couldn't get into my computer any other way, and the graphics for Safari were messed up. Firefox was okay. Good Luck!

Vertical lines on dual display after boot up with NVIDIA GeForce 6600 on G5

I have just upgraded my G5 Quad from OS 10.4 to OS 10.5. Now, whenever I boot up the dual display is split into vertical stripes. I can fix it for that session by unplugging one monitor and plugging it back in again. If I boot up from the 10.5 install disc - same problem. If I boot up from the 10.4 install disc - works fine. The display does not go into vertical segments during the grey start up period, but only when the desktop appears. Anyone got any ideas?

Hi-
I think what you are seeing is a result of poor, possibly failing, VRAM.
The stripes sound very typical of VRAM errors, and the fact that dual monitors in Leopard are added to the mix furthers the theory.
Leopard uses the graphics card much more than Tiger, that is, pulls more resources (power) from the graphics card.
Add the load of two monitors at relative high resolution, and marginal VRAM can exhibit symtoms of being so; marginal.
I'm curious as to a possible third work around. If the monitors are equipped with power buttons, does cycling one off, then on, allow proper display at the desired resolution?
Also, is this Geforce 6600 the 128MB version, or the 256MB version? This is listed in the System Profiler/Graphics/Displays.

IMac 2009 frozen after booting and startup

So, a few days ago, my iMac got stuck in the white loading screen that everybody says. It happened before already, and at the time, I just booted holding the key C and installed the OS with the CD. That went ok, nothing wrong. But then, a few days ago as I said, it happened again. At first, I tried booting it with the keys Command + Option + P + R to start with the OS utilites. I tried several different keys combinations and nothing worked but the C. So I booted it again with the C key. I installed the OSX Leopard again but now, when I turn the iMac on, it will go to the desktop screen just fine BUT it is frozen still. The mouse cursor is at the loading colourful ball and I can't use nothing, it just stays there forever! Like, I can't even click at the Macintosh HD folder or the at the Finder in the menu. It is really frozen at the loading cursor ball and it stays there forever.
Does someone know at least what is causing this?
How can I solve this problem without going to Apple Care? I do not have the money to leave it there, since the Apple Care in Brazil it's expensive.
Please help! I would be forever glad!
PS: If there is any doubt, this is the loading cursor I was talking about, and it's driving me insane!!!

White Screen with revolving circle after boot and login.

Reset PRAM - Same Issue
Removed internal components and cleaned dust from fan, removed/re-inserted memory after cleaning with air. Same Issue.
Booted up in recovery mode (CMD R) and reinstalled Maverick. Rebooted..Same Issue.
Booted up in recovery mode and ran disk utility. Verified MAC HD1 and HD2..all good.
This is when I discovered that I had only 16MB of free space on my 2TB primary drive. I have TB free on second drive.
Question: Is there anyway to boot up and move files to secondary drive? Maybe if I free up space it will boot?
Thanks!!
Chris

Try a Safe Boot from the HD, (holding Shift key down at bootup), it may give you a bit more free space to boot with, if that is the problem, otherwise I think you may have to Intall MavX on the second drive & boot from that using alt key.
