Why does my screen flicker every 10-15 seconds?

like a blinking? do you have the late 08 MBP?
if so go to system, energy saver, and select better performance. Your screen should be flicker free.

Why does my screen minimize every time I push the left shift button?

Why does my screen minimize to left top corner every time I push my left shift button?

I would try going into your System Preferences and reset your keyboard settings to the default setting. It is possible that somehow your shift key got bound to something it shouldnt have been.

Welcome to Apple Support Communities
If your Mac is in warranty, make a backup of your files and take it to an Apple Store or reseller, because you will get it repaired free of charge. There's no need to know what's failing when you will get it repaired for free.
If it's not in warranty, you would like to know what's failing. It looks like one of the GPUs of the computer is failing, but to confirm that, first restart your computer after flickering. Then, after starting, open Console and look for the lines that appear with the same date as the display started to flicker. Also, look for messages like "GPU Debug Info Start", that shows a problem with your GPU.
In both cases, you will have to take your Mac to an Apple Store or reseller. However, if it's not in warranty, it will be a very expensive repair, because the MacBook Pro with Retina display has got everything soldered except the flash storage

Why does ipod screen flicker and shut down?Possibly need new battery?

Ipod screen flickers, but music still plays. Then it will shuy down. I ahve restored it , but still does this. My 9 year old lives on this ipod, he is going through withdrawal now! Possibly new battery? Thanks

Might as well be a hardware defect, especially if you can still listen to music after the screen shuts down.
To make sure it is not the software, set it up as new device, without using the latest backup afterwards.

Why does the screen flicker on new MacBook Air when I scroll?

I just bought a new MacBook Air a few days ago. I notice that the screen flickers when I scroll and is not anywhere near as smooth as on my old MacBook Pro.

I've experimented with this a little more. I don't think the screen is flickering necessarily but the scrolling is not always as smooth as I remember it on other computers I have used. The text looks jumpy. Maybe it's the operating system? I think it happens more if there is a lot of information to scroll through.
Is this normal?

Why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor?

why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor? it only works if i turn the computer on with it already plugged in.

Do you have gfxCardStatus installed? Is your monitor set to "Integrated" or "Discrete". You want it set to Discrete to drive the external HDMI display.
Try resetting the PRAM and SMC

Are you sure you have a good miniDisplayPort to HDMI cable?
Do you have another HDMI display you can test against (your neighbor's HDMI capable TV).
Do you have friend that can test the cable using their Mac and maybe their TV or a monitor that has HDMI input.

Why does my screen turn black when I play iTunes while working on iPhoto?

Why does my screen turn black when I play ITunes while working on iPhoto? I can't click off of the screen but get a message that reads Shut down computer by pressing button in back then turn computer back on by pushing button in back. That's followed by Chinese letters (which I cannot read). I have had other problems when playing iTunes (actually, a radio station on the Internet) while working on iPhoto. Before, I got a window that would pop up and tell me I had no disk space available, that I would have to quit applications that were open. Not many were open.
It would be nice if I could solve this problem once and for all.
Thanks in advance for all the suggestions. I truly appreciate your help.

That was easy. Thanks. Jan

Why does the screen on my iPad mini jump around? Apps open and close, I can't get back to the home screen. Is my mini possessed?

Why does the screen on my iPad mini start jumping--larger, smaller--can't close apps. I reboot and still it happens. Any suggestions?

If the unit has NEVER been jailbroke, first try a system reset. It cures many ills and it's quick, easy and harmless... Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, if you have IOS-7, read this.

Why does my screen come up dark when I press the camera icon?

Why does my screen come up dark when I press the Camera icon? I can neither take pictures nor look at the photos I have saved.

Doulbe tab the home key to see the task bar. Touch and hold any of those icons until they jiggle, then delete them by touching the minus sign. Then reboot the pad by holding the sleep and home buttons until the apple logo appears. Ignore the red slider.
You either have another app open that is using the camera, or you just have too much stuff in memory. The reset process should clear it up.

Why does my screen have a circle with contact name

why does my screen have a circle with contact name

it might be the recents feature showing up on the home screen, this can be switched off.Once you’ve completed the upgrade to iOS 8, head to Settings > Mail, Contacts, Calendars. Scroll down until you see the Contacts section and tap on Show In App Switcher. Here you’ll see the options for displaying contacts in the app switcher screen: your iPhone favorites, your recent contacts, or both. Note that if you enable both favorites and recent contacts, your favorites will be displayed first, and you’ll have to scroll to the right to see your recent contacts.

Why does my iTunes hang every time when using automatic device detect?

Why does my iTunes hang every time that I connect either of my devices (iTouch-4th Gen, iPod Nano-5th Gen), to my Win 7 (64-bit) PC desktop? By the way, this does not happen if I open iTunes first, and then connect the device. So my workaround was to simply uncheck the checkbox that allows iTunes to start automatically upon device connection. This doesn't fix the problem, but it allows me to synch my device, but it would be nice to be able to have the autodetect work properly, so that iTunes would start normally without locking up on me and freezing. That's what I mean by 'hanging'. My whole computer doesn't freeze--only iTunes.

Hello E
Start with finding the path where the songs are on your PC by right clicking the songs that are missing in iTunes and click Get Info. You should get a window that pops up and in the Summary tab; the path will be there. Then navigate to where it was and see if the files exist. Other than that you can try to search your computer to find those files. Checkout the articles below for tips on finding the missing music, also if some of the tracks are downloaded from the iTunes Store you can download the tracks again by deleting the missing tracks from iTunes and then navigating to the purchases section in the iTunes Store to download them again.

Why does my router disconnect every time I sleep the computer? Why did this only start to happen recently?

Why does my router disconnect every time I sleep the computer? Why did this only start to happen recently?

Actually it does with Ethernet too: http://support.apple.com/kb/HT2412?viewlocale=en_US&locale=en_US
What happens when the Mac goes to sleep (not just into idle mode or display sleep)?
On all Macs:
The microprocessor goes into a low-power mode
Video output is turned off, and a connected display may turn off or enter its own idle state
Apple-supplied hard disks spin down; third-party hard disks may spin down
On portable Macs:
The Ethernet port turns off, if applicable (see note below)
Expansion card slots turn off
The built-in modem, if present, turns off (see note below)
An AirPort card, if present, turns off (see note below)
The USB ports only responds to the power key on an external keyboard (see below)
The optical media drive, if present, spins down
Audio input and output turns off
Keyboard illumination, if a feature of your portable computer, turns off
But see the note about selecting, "Wake For Network Access" in Energy Saver preferences.
Note: Portable computers have no network connectivity when in sleep mode, but can wake if the Energy Saver option "Wake for network access" is enabled. If you wish to use file sharing or don't want to interrupt your Internet connection, you should not manually put the computer to sleep, and you should drag the "Computer sleep" slider to Never.

Why does the slider disappear every time I use it to move the window (Windows: FF 32.0)?

Why does the slider disappear every time I use it to move the window (Windows: FF 32.0)? How do I get the slider back?

Problem solved: I have been using Walnut for Firefox ver. 2.0.28 theme. For some reason this has been causing the problem. Started FF in Safe Mode, and the slider problem disappeared. Then proceeded to re-enable the Walnut theme: the problem reappeared. Disabled Walnut theme and reenabled all my other add-ons (about 6 of them). Still no problem. So, clearly there is a problem with the use of Walnut theme in FF ver. 32, at least on my Windows 7 installation.
Thanks for all your suggestions and help. Good job, all!
