OS X :: Unibody MBP Screen Freeze & Screen Height Cluster?
Mar 19, 2009
Just got my new macbook pro last week, been having some problems ever since i changed my ram to Kingston 1066MHz DDR3, supposedly to be compatible with the MBP.
I have experienced horizontal lines of flickering and freeze of my entire system, which requires me to do a hard reset. I have recorded a video of it here.
I have also experienced similar type of freeze, but the screen pixels just cluster together at the top 20% of the screen, much like this.
I have ALSO experienced my keyboard totally not responding when i try to recover from a password saved screensaver!! The mouse is working fine, but the system just can't detect any keystroke input, forcing me to shutdown forcefully again!
I don't have time to send in my MBP as i need to work on it, and cannot do without a machine, any ideas how to resolve this?
May i also know which rams are compatible with Mac?
never had a problem with a freezing mac in 5 years of mac use so wouldn't like it to start now. Whilst using firefox this morning it froze, force quit wouldn't work, entire screen froze. Keyboard shortcut wouldn't allow me to shut down, so I had to shut down via the on/off switch.
When I came to switch it on again it loads up to the log in screen, the mouse moves around the screen but when I click on my username nothing happens. I've taken out all USB cables, switched wireless keyboard and mouse on and off etc, restarted, no joy. Next I tried to startup with the c key and install disc, but again I got to the log in screen and nothing happened. I'm assuming as I can't log in and get to a desktop that is why it's not allowing me to start with the disc?
On my late 2011 imac 21.5" I have been getting a consistent problem since the last OS update. After the screensaver comes on, or, if left to sleep by it's own devices, either my screensaver freezes or the gray screen won't recover from sleep. If I move the cursor with the trackpad it clears the gray screen where the cursor moves around. I can usually clear enough that I can hit the login button and log in after pushing the power button. This is a new phenomenon since the latest OS update.
Today I left my MBP on without the Power Adapter for calibration. Three hours later, when I arrived home, I found it with a black screen, unresponsive (didn't respond to any key or mouse movement whatsoever). No, the battery wasn't empty of charge, it still had half the charge! This is the second time this happens to me, I can't seem to think of a reason for this to happen.
I believe JDownloader was open, but not doing any downloads, but I'm not sure whether it was open or not, but besides it, nothing else was open.
my laptop is 2 months old and i've noticed the past few days my computer freezes for a good minute whenever i do full screen videos wether its youtube (safari browser), or downloaded video it still freezes and the dock disappears along with it.
I have just installed a new Mac Pro. Everything works except I get occasional mouse pointer freezes. They last for about 1 second each time and seem to occur randomly, on average with 1-2 min intervals.
The only things I have installed on top of OS X so far driver wise is MouseWorks to power my Kensington trackball. I use my older large full-keyed white Pro keyboard and only use the smaller wireless one remotely. I have tried deactivating Bluetooth but the mouse freezes still persist.
I've reseated memory and my hard drive, but still if I bump it freezes or black screens. I'm going to pickup an external hard drive to backup my data, because this is scaring the crap out of me.
My iMac G5 (running 10.4.11) freezes at the blue screen, after recognizing the mouse, but before the login window. Some form of energy saver must be working because after the blue screen dims, moving the mouse will brighten it.
Steps I've taken: Hardware test - everything passed (RAM, logic board, airport, display, etc...) Zeroed the computer (7 times) and fresh reinstall
I CAN boot up in Safe Mode, Single User Mode, and Verbose mode. I can boot from CD, Knoppix CD, and into Target Disk mode (thank god for this MacBook I'm on now...)
Here's the system log (I've edited in comments and out personal info):

I used MacbookPro(2011 8,2), after install update 10.7.2 include today 10.7.3, all system will go freeze every time I click full-Screen button. it freezed in go full-Screen animation, and always played half of the animation and freezed. I find out if I used my AMD 6750 GPU, all problems are missing.
The logs I found below are repeated once and once again while system freeze: 12-1-26 下午9:38:16.000 kernel: **** Debug info for apparent hang in Main graphics engine ****12-1-26 下午9:38:16.000 kernel: ring head = 0x000023b4, wrap count = 0x 012-1-26 下午9:38:16.000 kernel: ring tail = 0x00003470 ring control = 0x00003001 enabled, auto report disabled, not waiting,
my macbook recently started freezing and then shutting down giving 3 beeps afterward. I know 3 beeps is traditionally RAM, but here is a picture of my screen when it freezes. Do you think its GPU and logic board problem or is it really the RAM?
Been having a few huge issues with my new MBA 13".
#1 - Putting the laptop to sleep. I put the laptop to sleep and put it in the bag and at some point it wakes back up. If I don't remove it during the day by that afternoon/evening when I go to remove it the battery is at 0% and it's fully discharged. One day I took it out a couple hours in and the fan was blowing like mad like it had been running for a while, when I opened the lid I had a black screen and it was frozen. Disabled waked for network access but it was no help.
#2 - When the laptop goes in standby and I open it back up I get a beach ball forever - I've tried to let it go for upwards of 30 minutes and it never unfreezes, but I can move the mouse around. I ended up telling the laptop not to standby when it was plugged in to a power source otherwise I ended up always losing work.
I have a 15" Macbook Pro that I purchased 5 years ago. It is getting old, but I replaced both the ram and the harddrive about half a year ago. I have been having problems with the screen freezing for a while now. At first someone told me that my harddrive was probably causing the issue because it had been corrupted. I replaced it. The problem did not go away. Then I was told the problems I was having is software corruption, so I wiped the harddrive and reinstalled snow leopard OS. This did help for a while, but recently the problem has returned. My computer screen froze 3 times in an hour and I have static lines running horizontally across my screen. I have a screenshot example.
I woke up this morning and my iMac G5 (w/ Leopard) was frozen. I restarted it manually, but it would freeze on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM - any other ideas?
What can I do in Safe Mode that might fix my comp? I haven't recently installed any applications, and I have all "open at login" items turned off.
I recently got the Core i5 iMac. Basically, while I'm working doing everyday things like browsing, coding, iMovie etc...my screen just freezes and there are squares of white noise pixels scattered everywhere. I can see the mouse cursor as I move but the image is so distorted that I dont know what Im clicking. Restarting the machine fixes the problem.
I made a youtube video so you guys could see what I'm talking about here: http://www.youtube.com/watch?v=sVHCn9VSyIA
I bought one of these via ebay and in negotiaton with the seller. Since this is my first foray into the macworld, i'd like to know from the people here with tech knowledge what's possibly broken. The screen broke during the transportation.I've posted some pics of what is happening.
I have the infamous bugged model, the Late 2008 Macbook Pro. Famous for its screen flickering on the 9400M Nvidia graphics card.
I am currently using the 9600GT Nvidia card, and have some across a few... problems. First of which: Hard Freezing. I know this will happen occasionally, but I had to shut down my computer 3 times in 4 days because of a hard freeze. 2 of the times, the hard freeze was accompanied by my screen just going absolutely CRAZY.
Here is a slight example of what it's doing, but it's not exact (since both times it did something different):

Both times, before the hard freeze and flickering, my iStat Pro told me my CPU temp was between 99 degrees Fahrenheit and 103 degrees Fahrenheit. I am wondering if these low temperatures could have ANYTHING to do with the freezing. This problem has just cropped up recently, and I have never had such low temperatures on my mac. I have Fan Control installed because my fans on my laptop weren't cooling off my laptop well enough... the 9600M GT card runs really hot.

Has anyone else with a new MacBook Pro with Retina display notice a slight uneven yellow tint to their screen? On my screen it appears starting about midway down the screen and is more noticable on the left hand side. It is very faint, but enough to make me notice it when scrolling through webpages and the such. I am wondering if maybe this is the same glue drying issue with the iPhones that just came off the production line?
Also, when trying to run WebGL content in Safari (haven't tried it in a different browser yet), my MBP completely hard freezes and requires a power cycle to get it running again.

I am having very frequent system freezes (multiple per day) then when restart the restart is very slow. Activity Monitor shows TechToolsupportDaemon taking up 99-120% of CPU for extended periods. I have a MacBook Pro 15-iInch, Early 2011, with 2.3 GHz Intel Core i7; 8 GB 1333MHz DDR3; Intel HD Graphics 3000 512 MB; running OS X 10.9.3 (13D65).
I am also having episodes for sudden abnormal graphics with jagged lines, Screen split vertically with multiple horizontal lines. Screen becomes totally unreadable. Then sudden total screen freeze.
I made rescue system drives on flash drive when I first shifted to Maverick, so I could use Disk Utility to Verify and/or repair the main disk. When I upgraded to the next edition of Maverick, my flash drives no longer worked. I tried to upgrade the flash drives to the new system, but there was not enough room. I tried erasing the drives but now I have a flash drive with only a small amount of space, the rest is hidden and locked.
What do I need to do to correct the problem of frequent freezes, and then How can I free space on my flash drives?
1. When closing the lid or pressing the power button the computer freezes, the fans start spinning fast it stays like that until it drains the battery. This happens every time.
2. Start-up times are very long, like 3 or 4 minutes. This also happens every time.
3. Now after a fresh snow leopard install it doesn't even start up completely, as it stays showing a light blue background and I can hear the music of the introductory animation.
4. Also, the keyboard is unresponsive at the login screen, but the mouse cursor moves and the display goes to sleep normally. Clicking anywhere with the mouse also produces no effect.
5. It seems to work OK in safe mode.
The macbook worked ok with the factory installed Tiger. The SL DVD is OK, as its installation has been tested on another Mac. The machine's advanced hardware test passed successfully. Resetting Pram and SMC did not solve the problem.
Whenever i try to "shut down" my MBP, it will freeze at the blue screen with the spinning wheel (that keeps spinning like 'eternally')! Any idea how to solve the problem? I tried booting from the installation disk and repairing disk with "disk utility" but to no avail. Have also tried repairing disk permissions... Any idea how else should i tackle this problem? Currently i can only switch off my MBP by holding the power button (forcing it to shut down).

I was walking into my friends house the other night with my Macbook Pro in an Incase sleeve and it fell out of my hands and onto the concrete. I assume it landed on the edge of the screen and bent it inward. The screen and everything work properly and the issue is only cosmetic but it's driving me crazy.
I have an appointment at the genius bar tomorrow but would like to know how much Apple would charge for repair beforehand. If anyone has experience with this please chime in.
This has happened 2 times (rarely). Basically, when I wake up the macbook pro, the screen would remain "blank". I know the screen is on because I can see the mouse pointer but the whole screen is black. I'm assuming Finder has crashed?
I don't know how to restart on the macbook (ctrl + alt + del didn't work, using option didn't either) so I just held down the power button for 4 seconds and restarted that way.
i have a 2.0 unibody macbook, and i have had it since november.. it had the washed out screen and slanted function keys, so the guy at the genius bar took one look, logged it and im getting a new screen and top case. i love the genius bar and apple support =]
what should i used to clean the aluminum unibody, when it comes to the lcd screen i know alcohol and other solutions are bad for lcd because of the thin flim layer but the macbook pro has glass so it should'nt hurt the screen to use those kind of products.
