for the last week or so my MBA has been showing a ~3 inch bar running vertically along the middle-left of the display. Until today, the area looked just like blurry pixels (some things like graphics would still appear, so I don't believe the problem is with the pixels themselves). Now the area has become a gray bar of pixels.

Ok, I've noticed this week that my 2010 13" MBP hangs a lot when it plays any videos I've bought off of itunes (it's fine with other videos). I mean anytime a itunes video pops up on my itunes player, the whole computer hangs (beachball of death and can't do anything). And it hangs for quite a bit (haven't timed it but a minute maybe?)
At first I thought it was the graphics card as the first time I realized what was causing my computer to randomly freeze up (it's been starting to do that this week but at first wasn't sure what cause itunes was in the background) it gave the wierd color bars on the video screen for the video it was playing (I have itunes play the video in the small box on the left bottom corner). Like the whole video screen was random fubar color bars and not the video (it took a minute and then eventually played fine after me reclicking the video). It has not done that since.
I played around with it and noticed it seems fine when I play videos I have not bought off of itunes but it reliabley hangs the whole computer when I try to play a video bought off of itunes. It eventually plays but it is really annoying particularly cause it holds up my whole computer until it resolves whatever issue it is.
So, hardware or software and any suggestions if it is software on how to fix it?

all threads are outdated from 2006 and 2007 as far as I looked, or has a different issue. My macbook is a 2009 model running 10.6.4, using a linksys router, signal will drop for no reason. The bars are full, but nothing will connect. NO messenger, web browser, or downloading software will work, like its dead. This usually happens if I keep my computer on over night for huge downloads (1GB+).To fix this, I just have to click on the airport icon on the top right corner of my screen, choose disconnect, wait 3 seconds, then choose reconnect and it will work again.

Over the last week, my 7 year old Powerbook G4 began showing faint pixels in the background which is more obvious if you are scrolling over menus also when a menu is highlighted. Unfortunately this seems to be affecting DVD playback because it will show blinking green vertical lines inside Front Row. This image within OS X 10.5.8 will show what I mean: [URL]. Does this means the graphics card is failing?

So I have a 2009 iMac.Earlier this year, I upgraded to Lion. A little while after this upgrade I started running in to an issue that is now making my computer unusable. When working on graphic or labor intensive activities I am receiving Red Green and Blue pixels around my screen (see picture below) Shortly after this happens, my screen freezes and becomes unresponsive with these pixels still up OR it will completely glitch out, blinking and causing the whole screen to go crazy. Things I have tried so far, rebooting my system from scratch, replacing video card (not cheap )
Info:
iMac, Mac OS X (10.7.3), Late 2009

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:

I own two Intel-era Mac Pros, one at work, the other at home office.couple months ago both started having the same problem: a mix of freezes/hangs and weird graphical artifacts showing up on the screens.Usually I need to reboot. Usually a reboot fixes the problem for a while until it recurs. If it was just one computer, I'd figure disk problem or graphics card.But the fact that both have been affected at the same time makes me suspect some software issue or possibly a trojan/virus.

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?

So after waiting 4 weeks my High-res Glossy MBP FINALLY arrived...I was so happy. Got home switched it on and WOW it really is a beautiful machine...After using it for about 30 mins however i noticed a small dot to the lower right half of the screen... I looked closer and realized it was either a dead or stuck pixel( I dont exactly know the difference). I did a few test on it, and its ONLY visible when a light color is on the screen (White, Gray etc) However when the screen is DARK blue, Dark green or black it cant be seen at all...
It kind of looks like a TINY speck of water or liquid the size of 1 pixel stuck under the glass... I noticed that it does get lighter and darker when i adjust the brightness of the screen. Can anybody give me some tips? Anything i can do to fix it? Is it in fact a dead or a stuck pixel? I tried the JSscreen fix which is basically a online tool that opens up a flashing screen...Ive had it on for about 30 mins...but no luck

I've noticed recently that when in Finder, all folders/files have a Modified Date of somewhere in January 2009 or January 2008, regardless of when it was actually modified/created. My clock at the top left-hand corner says Oct 20 though. Any thoughts?

I have a mac running OS X 10.4 We have one netgear router in the house where I work and various different things connecting to it. You'll have to forgive me, all my computer knowledge is based around systems running windows and while I enjoy my mac and can use it for work this technical stuff baffles me. I've just been given my own office. When in there, door open my airport fluctuates between 2 and 4 bars but web pages just don't seem to load, eventually timing out. I'm probably only about 30ft from the router but there are walls (and a mirror) in the way. Could this be the problem. From home I brought something in called Wi-Fire, it's a massive wireless dongle that has a range of 1000 ft. Would it? If so then how the hell do I get it to work on my mac laptop?

So I just got my MacBook, mainly for school. The wireless service at my school requires a username and password so I went to the place and paid the 10 bucks for it. They said when you open up "Internet Explorer" (I chuckled) that a window would come up asking for your permission to continue or whatever and then you have to put in your username and password. When I join the network in Airport it says I have full bars however when I open up Safari or Firfox it instantly says that I'm not connected. What can I do so that it will ask me for my username and password so I can actually use the internet? I have gotten to the page where it asks me for my username and password before but I hadn't yet set up an account so I just exited out. Now I can't even get to that page! Hopefully there are some people out there that use the same type of wireless service at their college...

I get great wireless connectivity under Mac OS X, since the wireless base is in the room right next to the MacBook Pro, but under Windows XP Home Edition with the Mac drivers installed, I never get above two bars, and connection drops every 20 minutes or so. Windows is completely updated, all boot camp drivers are updated, everything.

Could somebody tell me what that app is that I see running in many people's finder bars? It has the red and green bars on it running vertically. I can't figure out what it is. I've tried searching, mroogle, etc but when you don't know the name of it, it's pretty tough to find.

I have had my Laptop for over 3 years now and with really no significant problems. A couple of days ago though, my laptop display got 3 vertical black/white/black bars on the right third of the screen and I am just curious if it is dying. I am connected to an external display and it's been awhile like this, but it makes it impossible to use as a laptop anymore.

I've just switched from an iBook to a MB. My iBook always displayed 4 bars of wifi here at home (my wireless router is in the same room). But my MacBook often displays only 3 bars in the same room. What could be causing this?

I have the 2.4ghz aluminum macbook, late '08. I go to a community college that is pretty large, compared to community colleges. I have full bars most of the time at school but about 50% of the time there is no connection. On mozilla i get an error to contact the server administrator and i just get a no network on safari. I installed windows 7 and there is also full bars but no connection. My friends, who have PCs, connect fine. There s a dell netbook and a 50lbs Toshiba laptop.

Yesterday my macbook's wifi started getting really slow to the point where it takes 10 minutes to load a webpage. I reseted my router and everything but it was still slow. Then I noticed that my iMac and Ipod touch had full internet speed and everything. What happened? I didn't do anything different from my normal routine at all.
I was running on old firmware for my macbook and decided to attach an ethernet cable to get the latest and greatest but it didn't fix the problem.

I have the white macbook and I got it a little less than a year ago. For the past week, sometimes when I go on the internet (firefox or safari) it just won't load. Like the blue bar that shows you how much has loaded isn't even visible and it will just say "connecting". But when I look at my airport icon that shows me how many bars of internet I have all the bars are full so I have internet connection. It is not just one type of internet browser because it does it on both safari and firefox. And it is getting really annoying because I will be browsing the internet and it just won't load or connect at all. Even if I wait.

I'm totally freaking out right now, I have a MBP 17" 2007 model with 2.66 GhZ Core 2 Duo processor, 4GB RAM and GeForce 8600GT graphics. I was working on Adobe Acrobat when it crashed for some reason. I restarted the computer and clicked on "Send to Apple" (error report) but it suddenly hanged on this screen with bars all over my display

I have a 19-inch Envision EN9410e LCD flat panel monitor. Right now I did a mirror display setup. The native resolution of this monitor is 1280 x 1024. When I went to System Preferences to change it to that resolution my LCD monitor shows the Snow Leopard desktop but it's in the middle of two black bars. I had to revert to 1024 x 768 resolution to not have the black bars show. Is there a way I can change it to the native resolution and not have the black bars on the top and bottom show up on the screen?

I am running Win7 using 3 monitors, with Ultramon to manage the monitors. I want to switch to a Mac but am worried about the lack of a menubar on each monitor. On my Win7 PC, each monitor has it's own app running, maximized to the size of the monitor. So I'll have 3 instances of Firefox running, 1 on each monitor, or 2 Firefox and 1 Word, or Firefox, iTunes and Ableton Live each on it's own monitor. I want to do the same on the Mac and have the menubar for each program on each monitor. This question has been asked in the past, but all the discussions are older. Just wondering if there have been any recent developments or if anyone thinks this will be addressed in the near future. There's a program called Secondbar, but that only works on 2 monitors--it adds a second menubar. [URL]..........
