When I connect my iMac to a hdtv, the screen goes white with snow
When I connect my imac to my samsung hdtv through DVI miniport to HDMI on the tv, the connection is fine for about 10-15 minutes and then goes white with snow. I had a macbook pro before and used to use the same connection on the same tv and it worked perfectly fine. Please help
Nope it won't do that on the mid 2011 iMacs. What you're trying is called Target Display Mode, the only way it would work is if the PC has Thunderbolt (which no PC has) and you use a Thunderbolt cable.
What you can do is hook up to two external monitors on your iMac (giving it up to 3 monitors) which is very cool and can improve productivity depending on what you use your iMac for.

When I started my Mac the screen was white with the Apple logo and power motion icon running. I attempted to turn off Mac then a message stating "Debugger called: <Button SCI>. Also "Waiting for remote debugger connection." What is my next step?
Hi , and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
And sorry to report that OSX is more Widows like than ever, but….
If that doesn't help Reinstall the OS. -
I have had a number of issues with my Intel Mac recently and had to reboot using disk utilities, safe mode, OSX recovery, but always come back to the login screen but when I type my password the screen goes white and returns to the login screen. My password is correct and the login does not jiggle as it would if the password was wrong. Please advise,
Back up all data if you haven’t already done so. There are ways to back up, even if you can’t log in. Before proceeding,you must be sure you can restore everything to the state it’s in now. If you’re not sure you can do that, STOP.
The procedure below may spare you the need for a clean reinstallation of OS X. If you don't feel comfortable carrying it out, don't. try.
Briefly, you need to delete the following file:
/var/audit/current
If you already know how to do that, you can skip the rest of this message. Do it, and try again to log in.
Boot in single-user mode by holding down the key combination command-S at the startup chime. If you’re using an external USB keyboard, it must be plugged directly into a built-in port on the Mac, not into a hub. Release the keys when you see a black screen with scrolling white text. In this mode, there’s no graphical interface; just a command line. Initially, you can’t make any changes to files.
When the text stops scrolling, and you see a line ending in a pound sign (“#”), type the following command:
mount -uw /
You must type the command exactly as given, with no mistakes. If you don’t feel able to do that, STOP. At this stage, no harm will be done if you make a mistake, but later, it will be. Press the return key.
Next, type the following command:
rm -i /var/audit/current
Press return. You should get the following output:
remove /var/audit/current?
If that's not what you get, STOP. Type the single letter N, press return, and try again. Otherwise, type the single letter Y and pressreturn.
Finally, enter the command:
exit
Press return. The text will start scrolling again, and then the system will reboot. Try again to log in.

When I went to turn the desktop on, the start up sound came on. Then the screen was white with an icon flashing. The icon is a file folder with a question mark on it. I cannot get it to fully turn on. HELP
Run a disk repair tool on the hard disk or install a new OS.

when i click on my external hard drive the screen goes dark and a msg pops up saying i have to shut down my computer by holding the power button and then restart it. when i do that i get the same result every time. it worked perfectly last night..
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Ifou don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.
I know the report is long, maybe several hundred lines. Please post all of it anyway. -
Hey ppl,my macbook is not booting and by that i mean u can hear the audio wave when its starting up,the screen goes white and then after a while there's a folder with a question mark in the middle of the screen...anyone,any ideea?!?Regards.
That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the hard drive data is somehow corrupted.
Put your install DVD into the drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the optical drive.
Once it has finished booting and you are at the Install screen launch Disk Utility from the Utilities menu. Is your Hard Drive in the list on the left?
If it is then select the First Aid Tab run Repair Disk and if that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead. -
i get a 3914 error when i try and restore my iphone 4. my screen goes white and all different colors what should i do
first try a different usb cable, remove all other usb devices, and try a different port in back on desktops if possible. if no luck see these
These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart. -
When I turn on my ipod touch the screen goes white and stays white.
When I turn on my ipod touch the screen goes white and stays white. It plays but all I see on the screen is white. I cannot change anything.
It iTunes is asking to enter the passcode then:
- A data recovery company may be able to help
- Restore the iPhone from the backup of the iPod. You can then get the data off and then retore the iPhone from the backup of the iPhone. -
Help! I just installed the latest update on my IPhone 4 and now I can't access my podcasts. When I hit the podcast I on, the screen goes blank for a second and then opens to the home screen with all my icons. What happened?
Try a reset which is similar to a computer restart and is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously you see the Apple logo and then release.

The screen shows the borders of the original site. Beneath the Mozilla workbar the screen becomes white, on the left and upper side there appears a thin red line. Nothing is downloaded, clicking the right mouse button doesn't solve the problem. It doesn't happen everytime I try to load a .pdf file. When I go to the same site using Internet Explorer I do not encouter the same problem, swiching to Acrobat Reader or FoxIt is immediate.
To enable this right you need Acrobat, not the free Reader.
However, starting from Reader X it is possible to add simple markups to any file, unless it has been specifically disallowed by the creator of the file. -

Please can anyone help me to open game centre. Thanks in advance.
Try closing Game Centre via the iPad's multitasking bar and see if it works when you re-open it :
iOS 7 : double-click the home button to open the taskbar, and then swipe or drag the Game Centre's screen from there up and off the top of the screen to close it, and click the home button to close the taskbar.
iOS 6 and below : from the home screen (i.e. not with Game Centre 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Game Centre app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't fix it then you could try a soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
