MacBook :: My Display Scrambles And Unscrambles Randomly
Apr 3, 2012
First of all, I've got a 2009 MacBook running Snow Leapord.
[code]...
Starting yesterday, my screen randomly started scrambling and unscrambling. It started while I was watching a video on Youtube. The video would freeze but the sound would keep going, and if I moved the internet browser window (Google Chrome at the time) my screen would become covered in hundreds of the same window. It's difficult to explain; it's like copies of the same window would remain wherever I moved it. Certain things returned the display to normal: Pressing F3 rapidly, hovering my mouse over the bottome of the video, and pressing Command+Shift+4 to take a screenshot to post with this (which is why I don't have one for you guys; the problem fixed its self when I tried.

My mid-2014 15" Macbook Pro randomly "loses" its retina display at the top menu (becomes pixel-y), where the battery, sound, and wifi logos are (on the top right side of the screen). A restart fixes the issue, but I want to know if this is an issue that can be fixed?Â

I've noticed that strange yellow boxes will randomly appear on my display. This happens both on my external display and hte laptop screen. I've attached a screen shot of what it looks like. It's not application specific.

My Macbook Pro (early 2013, OSX 10.9.4) does not come to sleep mode – 10 secs after closing the display lid apple logo starts glowing (blinking) on a random intervals.Â
I have tried the following methods that HAVE NOT solved the issue:
* PRAM reset
* SMC reset
* Power Nap is disabled (with enabled I still get the same issue)
* WiFi is off
* Bluetooth is off
* no external devices connected
* no antiviruses or other programs that I would suspect to cause this
* sudo rm -r -f /Library/Prefrences/SystemConfiguration
* finally reinstalled OS X, and I still got the same issueÂ
Surprisingly, if I enter to sleep mode via menu: Apple>Sleep, there seems to be no issue! I have tried changing pmset -1 lidopen 0 to validate if lid is preventing from going to sleep mode, however it has not fixed the issue. Â
I see this text in the Syslog:Â

I'm trying to diagnose our new intel servers and VNC.They're of varying configurations in terms of memory, disks, etc, but all are the new xserve model.
Here's what happens.
When connecting to VNC either through ARD's built in software or chicken of the vnc we can see the login screen perfectly, but as soon as we login it suddenly "scrambles." The second a monitor is plugged in the remote display "clears" and again becomes usable.
Here's what's been done so far;
Rebooted the server (VNC broken)
Ran software update (VNC broken)
Booted the server with a monitor attached (VNC works)
Unplug the monitor after reboot + login + monitor plugged in. (VNC continues to work.)
Here's the problem. When I reboot the server I don't need to go through a song and dance to login remotely after a reboot.

When I download albums in iTunes, it scrambles the song order. How do I prevent that, and fix it when it downloads in the wrong order?

My Macbook pro's display has started playing up. Having green flickering lines which come and go randomly, especially on images with a lot of black. Right now, the lines just disappeared as soon as I connected to mains, to start recharging the laptop. I'm using OS X 10.7.4 with NVIDIA GeForce 9400M.

My wife's macbook monitor is destroyed due to happy 2 year old. It won't be worthwhile to replace the monitor and it is not fixable without some expensive work being done on it, therefore I would like to use our TV as an external monitor and retire the macbook to being a mediia computer. I have connected it to the TV, and I see an empty desktop, as far as I can determine it looks like it is treating the TV as a secondary display - that the desktop is extended onto - so I cannot actually interact with the normal desktop. When I try to run things using keyboard shortcuts I hear some sounds of things starting, but I don't see anything on the TV.  So what I need to do is to have some way to tell it to treat the secondary display as the primary display.

I've had my Macbook Pro since December 2007 and only today I've noticed it suddenly getting hot when doing nothing but browsing forums on Safari, smcFanControl said it was up to a shocking 90 degrees Celcius. At first I just ignored it but it happened again just now but this time only went up to 75 degrees Celcius.

I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything

My external display (HP w2207) seems to conflict with my MacBook Pro (15 inch Retina display, early 2013) since I upgraded MacBook OS to 10.9.4.The external display works at initial boot of Mac but does not work after OS sleeps and I attempt to awaken, and while the external display is not waking, the Retina display flashes through different screen views, which only partially reflect my normal screen, or do not reflect my normal screen at all.Â

I have a mid-late 2008 MacBook connected to a Dell U2211H monitor using a Mini DisplayPort -> VGA connection.
When I use 1920x1080, I only get 60 Hz and the display is a fuzzy (text). Also, there are black bars. Why?
Will my issues be solved using a Mini DisplayPort -> DVI connection? Or should I exchange it for the 2209?

My brand new 15 inch MacBook Pro was working fine for a week. Today the display went to sleep and when I tried to wake it, it remained dark, items barely visible. I could see the display brightness meter changing, but the brightness did not. Restarting didn't help. Called Apple and they're going to replace the computer. Has this happened to anybody else? Note: I have the hi-res anti-glare display.

I have an early 2008 MBP 15" (I think detailed specs are in my signature) and recently (over the last week or so) when I move my laptop display up and down (physically), the screen has this thing where it gets inverted and what not. It is very annoying, and I have been having to constantly fiddle with it everytime I move my laptop around (I use it both as a desktop and as a laptop, so this happens a lot). I recently switched to using it clamshell mode as a means of avoiding this in desktop mode, but occasionally I'll still need to move it around places and what not. I was wondering if anyone has had this problem before, or has any ideas as to what might be a better solution. I would take it in for repair, but I don't really have 300+ dollars to spend on a repair right now. I think it might be related to the data cable connection to the display of the computer, since it is rather intermitment, and requires fiddling for the screen to not be inverted/messed up/displaying black lines, etc. I can post more details about it, pictures or something if that would help any of you geniuses out there as well.

I have a Macbook with Snow Leopard and I plugged an auxiliary display on mini-dvi port. The display of the Macbook is my primary display and the other is the secondary. Is there any way to set the auxiliary display to be primary and the Macbook display to secondary?

I have the Apple 24 inch LED display which has the glass panel. Do you think it would be strange to pair the 15 or 17 inch MBP with the matte anti glare display with the 24" display? It would be used mostly with the external display so I'm wondering if it makes more sense for both panels to be the same. As I already have the external display I'm not open to getting something else. I'm just wondering if having the different types of displays would mess with my eyes.

I use MBP (late 2011). I find the hunderbolt port to be similar to the mini-display port of older mac. I wish to have another display, but not ready to spend $999 over a thunderbolt display from mac. So would like to know if a Mini-diaplay port converter from apple would help me connect a exernal display via the thunderbolt port?

While surfing safari my macbook pro will randomly start highlighting wherever I move my cursor. It happens randomly and it is annoying because I can not get it to stop and it refuses to click on things because the text icon is displayed as it is in highlighting mode. I was wondering what is causing this and how I can stop it?

The issues are random slowdowns and lots of beachballs since yesterday.
At the moment I am running iTunes, Safari, Adium & Skype only.
Might add that it's Safari 4Beta and also the Skype beta.

I'm hoping for some kind of insight on a phantom random shut off issue I'm having. I have a 2007 2.2ghz MacBook Pro running Snow Leopard and upgraded to 4GB ram. Within the last month, it has started to randomly power off. At first it only happened when I closed the lid and it went into sleep, but when I would arrive at school it would have shutdown on the trip. In the middle of this, I also replaced the battery. The day I put the new battery in, the thing freaked out. It powered off randomly while I was working. I was in the middle of the first battery calibration so I thought it might be a battery issue. When I tried to power back on, it would start to load the desktop and then power off again. I couldn't get it through a full boot cycle. I tried various configs of old battery, new battery, with power, without power cord and nothing seemed to work. Reset the SMC and PRAM as well to no avail. The longer I let it sit the longer I could work prior to power failure. So I assumed it was FUBAR and walked away.
Next morning called apple care and of course, things seemed fine. However, 1.5hours in, shuts off. Crap, Apple Care said go to Genius bar get it checked. Three days at Genius bar, full hardware and stress test and everything passed flying colors. I thought maybe it was a naughty little gnome who had decided to move on and torment some other guy. 3 days go by no problem, then today during sleep it powered off again. Then tonight, twice while working with powercord attached (one time losing about an hours worth of Excel work, which was a nice bonus).
Since everything checked out fine, I'm struggling with what to tell Apple if I take it back for repair. I need the laptop, but trying to work expecting impending doom when it randomly decides to shutdown sucks. I have apple care, but if they can't find any issues then it doesn't do me any good.
Any suggestions? Is it worth trying to do a clean install or look at some kind of software issue? Has anyone else dealt with this kind of issue?

I just recently noticed that in the middle of doing normal things on my MacBook Pro, it goes to sleep randomly. I have the 2.4ghz 13" 2010Â model. It happened twice so far within a 10 minute period. It has happened while charging through the AC adapter. It wakes up fine like usual, and when i close the lid and open it up, it actually wakes up faster than normal. I'm wondering if i should contact apple, or bestbuy (i have a 4 year warranty there)

my macbook pro has started to just cut out randomly. I have had this with an expanding battery and haven't had the money to replace it yet, but I don't know if this is part of the issue. When my computer cuts out, it is as though the power cable has been pulled out and the whole system just shuts off in an instant. I know that the power cable has definitely not come out, though.

I've been using my Macbook Air for a while now. I noticed while I was working on my laptop, my 9 key keeps pressing by itself. I've tried to clean under the key and hitting it for the random keypress to stop, but it still continues. I would type somehow like this: 99h99e99999l99o9 or even worse.
