Intel Mac :: Having Unstable Screen Image?
Apr 18, 2012
Since switching to Lion, the screen image on our iMac has become VERY unstable. It frequently flickers to the right and even moves completely to the right and disappears. It also zooms in unexpectedly and cannot be restored to normal view without backing up a screen. Another annoying feature is that while the screen flickers and twitches, one cannot access hot fields to enter data or select pull down menus. Â

just wondering how I would go about capturing a screen image to be used on a forum.So I would like to capture a still image from a video in order to use it as my signature block in a group forum.Someone suggested I push the "Print Screen" button when I find the image I want.But of course Macs do not have a print screen button (at least not on my keyboard anyway).

I was changing my desktop screen saver. Now it says it is "Loading Images..." and won't stop. It is locked and I can't do anything.Everytime I click on my "System Preferences" -- the Desktop & Screen Saver comes up - has my old picture and states it is still loading images.
This has been going on for awhile and I can't seem to get it stop. The Colouful wheel goes around. Â

I am using an IMac connected to the internet via wlan. While my windows laptop which is connected to the same wlan has no problem, the imac connection to the wlan is very unstable. Working online is thus a problem.

I have a Quad Core Mac Pro running Snow Leopard 10.6.4. I've been having this issue for the past couple of weeks. Basically I have my monitor set to turn off after after 15 minutes of inactivity, my Mac Pro is always on. After 5 minutes of inactivity my screensaver comes on and stays on until my monitor turns off. When I move my mouse to wake my monitor, sometimes an image from the screensaver appears onscreen for a few seconds and then disappears when my desktop appears.
I have repaired Permissions, rebuilt my drive using Disk Warrior, installed the 10.6.4 Combo update but the issue remains. An image from the screensaver doesn't always appear when I turn on my monitor, this issue is sort of random. Usually my desktop appears right away with no static image from the screensaver.

i dropped my macbook. The screen was not responding any more but the backlight was still working. Now, i have opened up my macbook, because my insurance company gave me a new one. There is nothing i can see that is changed. So what is the problem here? I am not waiting to bring it to the store with a respond: It will cost you a 1000 dollar.

I just recently (a month ago) bought my first MBP 13" unibody. When I connect it to my TV (Panasonic VIERA G10 Series TC-P46G10 46-Inch 1080p Plasma HDTV), the image is bigger than the screen, tried to switch resolutions with no success. The connection is minidisplay port to HDMI.

I am a new mac user. I am trying to figure out how to enlarge the screen image so it fills the entire screen.I am aware that I can hold control and scroll with the mouse but that moves the toolbar out of view.I also have found a way(unintentionally) that it minimizes to the lower left side of the screen and when I enlarge it it stays on the left side of the screen.

When I try to boot my Mac G4 the light comes on the cd drive will open but nothing else happens. No chimes or screen image. I haven't used it for a couple of months but it was working then.

I have a 24" Mid-2007 iMac, with 4GB of ram. I'm trying to setup Boot Camp with either XP or Vista so I can run some CAD software (Solidworks) for a class I'm taking. I installed XP SP3 using media that had SP3 pre-applied, and installed the Boot Camp drivers that came with my computer, then downloaded the Boot Camp 2.1 update. However, applications frequently crash - windows update fails randomly, the solidworks installer crashed, internet explorer crashes, etc. I then decided to try out Vista - formatted the partition, started from scratch, same deal. Ran the Boot Camp driver DVD, applied the Vista Boot Camp 2.1 update, then the crashed begin. Windows Update failed about halfway through the updates, internet explorer crashes, didn't even bother installed Solidworks.
What is going on? I have absolutely no problems in OS X, and I've never encountered anything like this in XP or Vista before on other computers. Jokes aside, a fresh install typically works for a while. It makes me think its a hardware issue - but what hardware failure would only manifest itself in windows?

My bro is having one heck of a time with RAM upgrades. First he popped in two Kingston 2 GB sticks and thought all was well. His MBP 2.26 was fine for a few hrs until when he tried to restart and he got the 'gray screen of death' where nothing happened. just clocking, no apple logo. So we removed the RAM and put in the stock 2 GB. Started up fine. Put the Kingston back in. Would not start. Ok prob solved. Then he just got OWC RAM and put in 2 sticks. Ran fine for the night but he called me over late last night and he is getting the SBBOD when trying to open Photoshop, iMovie, and iTunes. I had to hold the power button down to get out. Definitly not normal. Restarted and it was fine. It shows 4 GB RAM...but again the machine locks up and we have to do a force shut off. So I just said pull that stuff out and let's look at this more closely. Maybe the sticks were not seated right or whatever. Inspected and everything looked fine. His friend was so fed up he ran and got his MBP 13 and opened it up (he has stock 4 GB) and put it in his machine. His MBP booted up fine and we played with it for about 1.5hrs and did not crash. He had photoshop and iMovie up at the same time running and the thing was working very good. With the 2 GB he said it lagged a lot.
So we're not sure. I told him to return the OWC and buy Crucial but now he's all up and arms saying "I'm just gonna waste my money and buy Apple RAM at the Apple Store and be done with this crap!!!!" he was pretty frustrated as he needs to get going on some work projects I guess and he now doesn't care if its gonna cost him $200. He says its peace of mind. Well not peace of mind for your wallet! thoughts? just a fluke? OWC I've heard a lot of good things but I've never used the stuff. I normally used Crucial. Isn't Apple RAM the same thing anyway?! his $... just think its weird that his machine didn't like 2 brands of RAM, kinda made me think its the machine...

My wi-fi signal keeps failing in the house, but the fixed connection is stable. This might well be a stoopid question, but can too many wi-fi devices cause a router to go unstable? In the house we have four macs, two iPhones and three airport expresses. The router is the standard one that comes with O2 broadband in the UK and has been pretty reliable until the last couple of weeks

I have had such instability issues with Firefox lately that I have temporarily switched to Safari. I started noticing this on 1.5, but has only gotten worse on 3.5, including 3.5.2. Here is a list of observations:
1. On my Mac, if Firefox is idle for a good time, say a number of hours, it tends to become very sluggish, sometimes even locking up.
2. I used to sleep my system overnight, and 90% of the mornings, Firefox would be locked up.
3. About 50% of the time after sleeping the system overnight, my whole system would be locked up. If not locked up, then the whole system would be very sluggish until I force quit Firefox.
4. I temporarily solved all of these "sleep-overnight" issues by making sure Firefox was shut down before sleeping the system. After doing this, the system just wakes up immediately and works well, like it did some time ago, before the Firefox issues.
5. My son using Vista is reporting the same set of things, in that Firefox locks up itself, and it locks up his whole system, requiring a system reboot. So similar, but worse (yeah, Windows, I know).

This is my second time around re-installing snow leopard - clean. Why is it so slow? The spinning wheel comes up all the time, even for mundane tasks such as minimizing a window where I have to wait 10 or 15 seconds at a time. This time around I installed all the latest updates and iLife '09 - but its still as slow as ever. I also downloaded latest version of firefox.
I uses a late 2009 Macbook Pro 2.53ghz 15 inch, and previous OSX flies on this machine. I'd like to go back to OSX Leopard but I can't cause I need the latest version of iPhone SDK which only runs on snow leopard. What's going on here Apple? Your OS is unstable and slow, and there's no acknowledgement from your site whatsoever!!

My G4 MDD Dual 1.25 has become a little unstable in the last few days, applications keep hanging, or just refuse to start (not responding message seen if I force quit) and it?s now a bit temperamental about shutting down or seeing flashcards. Now the only thing I done in recent days is install a Firmtek SeriTek/1S2 SATA controller, could this be the cause of this?

One happy side effect of the .3 upgrade is that toast now works with my HL-DT-ST DVDRW GA11N:drive. No unstable connection message, no coasters.. it's a miracle :-)

My macbook pro is connected to the internet via WiFi router, and it very often it happens that my macbook loses connectivity with it. WiFi logo shows the same signal strength, but all browsers (Safari & Chrome) can't load webpages.Â
This issue can be solved by turning WiFi on and off, but it happens again and again. It looks like connectivity loses when Macbook goes in sleep mode and get's back from it, but sometimes connectivity issues happen even without sleep mode switching. I found in the internet that this issue can be solved by turning off Bluetooth.

I just bought a tv to use as a external monitor for my mac however when i boot into windows 7 the resolution (1080p) is fine but its not filling the screen completely, there is 1 inch of black on the top and bottom and about 1.5 inches of black on the left and right sides. it does not do this when i am booted into osx.
i think this could be because of how hdtv's are made and the resolution isn't exact (usually a little bit greater) so windows isn't "stretching" the image to fill the screen. i think osx does it automatically but windows doesn't. if this is the problem how do i get windows to stretch the image? i tried switching the screen mode on my tv's remote but that didn't work.

I'm having a problem on my mbp screen, although it happened only once just an hour ago. The screen goes flickering magenta and white and some pixelated image. I needed to force shutdown using the power button because it seems to stalled. After restarting, it went to normal. I dunno if it has anything to do with the gfxstatus utility that I've installed the night before. I know it might be the nvidia graphic card itself but I just don't have a clue right now. My MBP is just 8 days old and my 1 to 1 exchange has expired since it covers the 1st 7 days only.
My MBP spec:
MacBook Pro 17" AG, i5 2.53 Ghz, 4gb RAM, 500gb Hitachi HD, 512mb nVidia GT330M video card, Mac OSX 10.6.3, with everything updated. Tthe attached pic is not showing the exact image since the screen was flickering etc and I'm just using a camera photo. I just noticed while I'm just surfing this forum + facebook, my temperature is at 67-70 degree celcius, which is high (normal around 38-45). I look at Activity Monitor and found that Kernel Task is using up to 80% of CPU. I have a feeling that this is not normal, and it had not happened before.

I've been having issues with my wireless. I use my home wireless network as my primary internet connection. I've noticed that I'll be using it without any problems, and then suddenly I notice pages arent loading (or if i'm playing WoW, huge lag spike.) The only way to get it going normal again is to turn the airport off and back on, and let it reconnect. Sometimes that fixes it for the rest of the day, other times I have to do that every 30 minutes. It just depends. I found [URL] but that doesn't seem to be the issue at hand, because my signal never drops, the connection just dies. Anyway of a fix? It's a pain in the ass to have to always turn my wifi on and off.

my name is David Francis and I publish a community magazine in Bowling Green KY. I consider myself fairly adept with computers and technology having been working with them since 1987. I was a full time web developer for 10 years prior to starting a magazine company in 2007. My experience (was) Microsoft (can I say that here?) and PC. I developed ASP websites using SQL databases and I was more or less a MS Partner having invested many years on the PC and the MS Software (lots of money too I should say.) I was "persuaded" to learn the Macintosh by a fellow publisher and friend who loaned me a computer and Adobe software for six months. I must say I reluctant, but realized quickly that I needed the tools and performance of the MAC.
I purchased a brand new MAC Pro in Nov 07 (2 x 2.66GHz Dual Core), this was the same month that Leopard came out and it was included with the new machine. It came with 2gb of ram which I upgrade (MAC certified ram) to 4bg about six months ago.)I immediately installed Adobe Creative Suite CS3 which I purchased as well as Office for MAC, Parallels so I could run Windows (sorry), and a logitech mouse and keyboard............................

Okay, I think this is the right thread to discuss this in, if it's not I apologize. So I got a 13" unibody MacBook back in February. I've got a 2 ghz Intel Core 2 Duo, and 2 gb 1067 MHz DDR3. I'm starting to run out of hard drive space, plus I want to dual-boot Windows 7 when it comes out, unfortunately we still live in a PC dominated world.
My questions are, if I replace it myself this will void my warranty won't it? I didn't buy any sort of AppleCare with my MacBook so I just have whatever the standard warranty is.
Second, is there a limit to the size of hard drive I can put in there? Does it have to be made by a certain manufacturer? And at any size does it start becoming unstable with my amount of ram and processor?

my question is if the internet is disconnected for a while and then connected again, will the system auto-start the schedule job again. Because the internet connection may not be very stable at the mid-night time.
