OS X :: Cursor Keeps Disappearing / Leaving Only Few Black Vertical Stripes
Apr 17, 2010
My cursor (in all forms) on my macbook seems to be disappearing--it appears that every other column of pixels has gone clear as well as a clear border, leaving only a few black vertical stripes as the normal cursor. It's a black outline when it's the hand and it's a few colored stripes when it's the spinning wait cursor.
Interestingly, when you do the ctrl+zoom in a few degrees, the cursor reappears.
If anyone thinks it matters, I was in the middle of backing up via time machine when it disappeared...

I have a MacBook Pro with Leopard. On boot, I get a screen of vertical blue stripes with the Apple logo, sometimes intact, sometimes split across the stripes. The spinning activity wheel is there too. After about 30 seconds, it gives up the ghost and the screen goes blank. It's still powered on, but just the screen is blank.
I've attached an image of what the screen looks like.
I've tried Command Option PR to reset the PRAM and VRAM but the problem remains. Any ideas?
Anyone come across this? I 've been having it a lot recently on my imac, not my pbook though, and I can't seem to find how to fix it... very strange behaviour, as soon as you start writing the cursor vanishes...make for some very hard writing I tell you...
Well, that's ms, they might even have it as an option somewhere that I cannot find...
I'm having huge issues with my 20-inch early 2008 iMac running 10.7.3. I upgraded my RAM (to 4Gb) 8 months ago and everything was running nice and easy until I upgraded to Lion. Either one of these things happen: My screen goes entirely grey or blue with white faded thin vertical stripes at random timesMac freezes working with any Adobe applications (mouse cursor still works but I can't click anything until I turn off and on)Mac freezes for a while and after a 30-second delay clicking and pressing buttons frantically everything goes back to normal
The strangest thing is that when I play Sims 3 for example (a beast of RAM and video drainer) nothing happens. I tried almost everything from repairing permissions to re-install my memory modules. I couldn't run the hardware test.
Note: I live in Brazil so sending my machine to a Genius Bar is completely off the question.

while surfing the internet (I was reading an article on CNN and scrolling down to continue reading), the screen color changed to tinges of green and purple. The entire thing froze...no keys, no mouse, not even force quit...nothing. I had no choice but to do a hard shut down by holding down the power button until the laptop just shut off (Macbook Pro). In the middle of rebooting, (at the grey screen with the apple logo on it, I got the familiar circular dial that ticks around as it loads) a screen wipe similar to the effect of some screen savers went from the top of the screen to the bottom turning the screen from grey into green and purple vertical stripes.
It also said "you need to restart your computer" and proceeded to tell me how to do so in four different languages. Upon doing so, the same thing happened...several times. I tried booting it into safe mode by holding down the shift key until the grey apple background appeared and it seemed to be working as the loading was taking forever. Alas, the same thing happened. I took the battery out and held down the power button for 10 seconds, put the battery back in only to suffer the same effect. The next genius bar reservation isn't until Friday.
I have 4 vertical stripes across the entire height of my monitor, the stripes are there even before I log on. My 17" imac is 6 years old. Do I have to buy a new computer?
For about two weeks I've noticed green vertical stripes appearing on my early 2008 MacBook Pro. As you can see the photo below, it doesn't completely obscure content on the screen. The problem is also transient. It appears, sometimes as a flash, then disappears. In the picture below, the issue continued for longer than ever before (about 1 min). Is my video card about to die? Could this be a bad connection?
Its a G5 iMac ihave been using for abt three years now. first i got the vertical stripes about two months ago and today when i tried to switch it on, it won't. I turned it off last night after use and when i tried this afternoon, it was hot and it does not turn on?
I have a Samsung 50" plasma HDTV (1365x768). Whenever try to connect my 13" unibody MacBook pro to the TV (HDMI cable + Mini DisplayPort->HDMI adapter ---> HDMI/DVI input in my TV), I get black stripes on each side of the screen. It's really annoying when watching a movie.
I use SwitchResX, I'm attaching screenshots with my settings. I'm also attaching pictures of those stupid stripes. I don't want to buy any more adapters and cables because they are pricey here where I live.
It's normal for magic mouse bottom black stripes to show wear and tear after constant use. Actually I am very worried to lose my expensive and wonderful mouse forever because of these "soft plastic" stripes.
I have this issue where my cursor just disappears on my screen. It still registers as there and I can click on things, but cant see the cursor until I bring it down to the dock, and it reappears. It happened a lot with my old mouse, even after I changed the battery, so finally I got a new mouse about a month ago... and now it's happening again.
I have a late 2013 Macbook Pro with retina display. I have had an intermittent problem with the cursor disappearing. It is extremely annoying and I haven't been able to stop it.
I reset the SMC, it worked for a while but the problem is back now.
Everything was fine. Then I ran the software update and there was Safari 4.0.5 and I decided to update. After my iMac had restarted, the OS went completely berserk. If I click the dropdown menus, they start to flicker and run trough over and over again by itself and I can't click anything. My mouse buttons do straight things, bring up the finder and then I can't even go through the folders. I can't write with my keyboard, it just gives me random letters and I can't delete them. I mean the computer went completely crazy. I've never seen anything like this and I've used this iMac perfectly now almost two years. Everything is just flashing, flickering, jamming, cursor disappearing and doing straight things, I can't do pretty much anything. This has to be a virus, right?
When I wake my computer half the time I do not have a cursor. Is anyone else having this issue?
Sometimes when I open apps and shake my mouse it comes back. I also usually use expose to start my screen saver and then shake the mouse to turn it off.
My MacBookPro 15" 5.3 worked fine until today, All the blacks (rgb 0,0,0) on the screen become red stripes.
When I boot into Linux or Windows the same problem appears, so it's probably a hardware problem.
I have no expensive adaptor to connect to an external lcd screen, so I don't know yet if the problem is in the mac screen or in the cabling or somewhere else...
Here are 2 screenshots of black squares a drawed in Illustrator, one taken on the mac (cmd + shift + 3)
one taken with a camera (where you can see the red lines)
I want to avoid the MacStore as I want to avoid missing my laptop for a month...
start up I get a black bar one inch from the left, approx 4 inches in diameter running from the top of the screen to the bottom. The Apple 'logo' plus all the finder 'words' appear on the right hand side of this black bar. The cursor will not go beyond the black bar. It's as though it hits a wall.
Simply using my Imac for watching tv on the web, Hulu, and left to help my wife get groceries in the house. My wife checked her email and closed Safari.
I came back in roughly 10 minutes from when she shut down Safari to see a black screen with white pinstriping, and the mac being totally unresponsive. Shut down and rebooted, sent off the report to Apple, and am now here with seemingly no problems.
Needless to say, as a photographer this computer is just about as important as my camera. Should I be worried? discovered the thread to this issue, which appears to be quite extensive.

I have a 2007 MacBookPro. shortly after installing Lion 10.7.3 and VectorWorks 2011 I started getting vertical blue and black lines across my screen on startup. They remain with in the apple while the computer boots and the everything freezes. I tried all of the usual fixes, recovery, safe boot, reset PRAM, battery, etc.When I tried to boot of a system disc I get a message sating that I need to restart my computer. Upon restart same problem occurs. 2 months ago I took the whole thing apart and cleaned out the guts. Reconnecting all cables back together, I came across, what I think is the camera cable. Since my camera has been erratic, i decided to test the problem with it connected and then disconnected. Connected same problem. Once i unplugged the camera everything went back to normal, until now. The same problem returned. I cleaned out the guts again. This time I unplugged the hard drive to try and boot off the C drive, but still get the same problem. This morning It decided to boot up. I was able to copy my essential files onto an external drive.
I've had this iMac about a year now, and i have had this problem for a while but thought i'de leave it for abit and see if it heals its self. As sometimes the line is more visible than other times and sometimes it's not even there!
I have 2 pictures which i snapped with my iPhone, so i will link you too them.
The line is not majorly visible, but it is just annoying considering i payed �1000 for this iMac.
My macbook is running Mavericks OS X 10.9.4, and I'm having difficulty getting rid of the vertical black columns on my computer screen when it is connected to my classroom projector. I've played with the resolutions, and the best resolution for the VGA display is 1024x768...Unfortunately this creates less than desirable black columns on my computer screen. Another teacher in my school has display settings of "1024x768 stretched," and her macbook does not have the issue mine does. However, I don't think she is running Mavericks 10.9.4. I cannot find this display option on my computer.
My screen had black and white vertical lines pop up over the entire screen then went blank and now at a restart the password then loading spinning circle happens then I get a blank white screen.It's a 27 in Intel iMac that is about 2011/12 purchase
In just about any program, if I leave program running, close lid, come back in about 30 minutes, my screen will be black. I can see cursor, but when I move mouse it will "erase" some of the black screen. I've seen similar forum postings, but in those the screen is locking up -- mine does not do that. I've taken in to Genius Bar, they've run diagnostics and found no problems.
I then have to restart, but in doing so it will bring up the Guest login screen, with a completely different wallpaper than my default.
Also, there, at times, is a "hissing" sound that no one can diagnose. At first we thought it was caused by a game in which there is the sound of a waterfall, but I'm now hearing it even when the game is not being played. Super drive has been checked and no problem found.
I get a black screen with a cursor when i start up. I have tried the cmb pr fix and that gets me here, but des not solve it and the first letter of my login, enter followed by my password and enter does not work either.
my Boot Camp install of XP—I successfully partitioned the disk in my new Mac Pro to install XP, but my problem occurs when re-booting to install XP itself. When the machine rebooted the first time to install, it stopped at a black screen with a blinking white cursor, old-school DOS style. Second time when I rebooted and held down Option, it spit out the Windows CD. When I put it back in and it appeared and I tried to select it, it spun up, looked like it was going to work, and then spit it out again, whereupon I got a DOS prompt asking me to put in a bootable volume and press any key. When I inserted the CD, it spun up, but pressing keys on the keyboard did nothing. I tried rebooting again. This time holding option yielded both the Mac HD and the Windows CD (no spitting out!). Taking this as a good sign, I selected the CD and waited. Same black screen with blinking white cursor as last time, no other response, no prompts, never progesses to an installer, pressing keys didn't help.
Has anyone else run into this problem? This is a brand new Mac Pro with the Radeon in it, I have a USB keyboard and mouse hooked up, and it has the latest firmware update.
EDIT: Seems the CD was bad. Slipstreamed SP2 into my original CD and went. Now I just need to get those ATI drivers.
