24" video will pixelate and eventually freeze and has to be powered down by holding power button
I have a 24" intel based imac 2006 model- Recently it has begun to show pixel blocks on the screen and will eventually lock up and has to be powered down by holding the power button.
Is this limited to the time you are using specific programs or does it happen regardless of what program you run?
It could be heat-related. Beofre incurring the expesnce of a new logic board, make sure the vent on teh bottom of the comptuer oare unobstructed by paper's etc on your workstation or by lint and dust. You canvacuum off any ling and get more cool air into the vents.
You may want to get a program like this:

I updated to IOS 7 on my Ipad 2 and now videos will not play, they freeze and skip and will not play. Can anyone help?
Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

My Mac Mini was not sending a signal to the monitor. I powered down using the power button and now it will not start. When i power up I get a strange 2 tone sound, like a warning alarm. The fan starts, and the light comes on, but no screen.
I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.
Reset SMC no changeRun the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

Wife's Mac Book Pro locked up. She shut it down by holding power button unitl it shut down, when she powers it up now it will not allow her to log in on the log in screen. Any suggestions?
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -
Standard definition You Tube videos will only play at 360p and 240p, no 480p. HD videos will play at 720p, no 1080p. It was working until yesterday. I have not made any changes to Firefox. I tried upgrading to the latest version. This is not helping either. I don't have this problem when using Internet Explorer. The problem exists on both of my computers.
hello kmcvety, this should be an issue which is going to be resolved in firefox 36 - you could try it out right now in the beta version:

mid 2011 21.5 inch iMac with lion video=freeze, will not restart for 30-60 minutes , today it took 14 hours before power button would restart it , is anyone else having a long restart after this problem?
Look in Activity Monitor (Applications - Utilities - Activity Monitor) and see if you have any runaway processes using a lot of %CPU.
I would also strongly recommend running Apple Hardware Test in Extended Mode. If it reports errors you can Google them or post them here. -
I have a new macbook pro and it freezes and email wont close
I have a new macbook pro about 6 weeks old and it is freezing when i walk away for a few minutes it goes tosleep and will not wake up until i hold power button to power off and then power on again. Also at about a week old it would not close email and that froze. Not sure what is wrong with this computer.
Visit macupdate.com where you will find several utilities that will do that. You can also do it using Preview in your Applications folder or with TextEdit.

Keyboard and trackpad freeze and unresponsive
keyboard and trackpad freeze and unresponsive happen occasionally.
This is not a rare case. Please do not want to circumvent nor dodge the problem and issue. Don't pretend that this prolem is minor and not important.
When there is something wrong, please admit that there is something wrong and appologize!!
Be responsible for those people who pay $1,800 dollars, which they earn for working day and night and till late night everyday!!This Apple article may help you with this issue.
Other users have reported that leaving any USB device connected to the MacBook Pro prevents the issue from occurring. A workaround for the moment, but not too onerous.
Best of luck. -
Just tried installing an update to OSX Snow Leopard. Prior to trying to update OS, I was running V 10.6.3. During installation, it locked up. Although the screen tells me that the installation will be completed in less than one minute, that was two hours ago, and the computer won't permit me to shut it down via the power button, as I get an error sound. What do I do now? Help!
Hold the power key till it shuts down, it may take a little while, try holding it thru the warning.
Then if it shuts down restart and open Safari/Preferences, General tab, and set "Save Downloaded Files to:"
Select desktop, if desktop is not available in the the drop down menu, click other, then select Desktop from the column from the on the left.
Then download this:
http://support.apple.com/kb/DL1399
This will download the "stand alone installer"
Click on the installer pkg and follow the prompts.
Hope this helps -

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
1. AppZapper
2. AppDelete
3. Automaton
4. Hazel
5. AppCleaner
6. CleanApp
7. iTrash
8. Amnesia
9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X

Time and date settings change when phone is powered down (not shut off)..
I recently installed the iOS 8 update and immediately noticed that the time and date settings would change when I powered down my iPhone. I did not turn off my phone, only clicked the button to power down or save power. I have tried all the fixes, suggestions, etc., but I am still having issues. In the power down state, I am able to receive phone calls or texts but when I go into my phone, the time and date will be off. It stops from the moment I click the button to power down the phone. Please don't get this confused with turning off the phone completely. This happens when I click the button for power down or power save, however it is described.
So, how do I fix it? Is the app/software for the clock the problem? Is the battery distribution the problem? For some reason, in power down mode, the clock is not receiving constant power in order to keep accurate time. It stops the moment I click the button. Any suggestions? fixes, etc. I could try. Apple support techs were absolutely no help what-so-ever.This sounds exactly like what is going on with my phone, http://www.idownloadblog.com/2012/10/19/iphone-5-date-time-glitch/

my phone turns off and does not turn on, even i tries holding power button n home button for few min.... its shows nothing. i connect it to the computer n it doesnt show in itunes. plz reply wats the prblm wid it
Hi kamalkumar,
I'm sorry to hear you are having issues with your iPhone.
The article below will provide some troubleshooting steps for this issue:
iPhone: Hardware troubleshooting
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 15 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged. Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
I hope this information helps ....
Have a great day!
