Target display mode has suddenly stopped working
I've been using display mode target using a cable thunderbolt between my iMac 21.5 inches (end of 2012) and Macbook Air 13 inch (early 2014) for about six months.
I had a few weeks off and had to return to find that I can enter is no longer target display mode! When I press Control-F2 on my keyboard connected to my iMac, that nothing is happening. I also tried Fn-control-F2. I tried different ports in case one of them is damaged. But nothing helped.
Anyone has any suggestions as to why target display mode would have stopped working so suddenly? I really like the feature of double screens between my macbook and iMac and would really like to come back!
I know target Display Mode will work, but only if I use the command-f2 from the login screen. After the connection, the command does not work. have you tried?

Some DVD players do not use the Windows default drivers so check with the manufacturer of system and

Hi all, my keyboard has suddenly stopped working. I was installing an upgrade of El Capitan (later) and when the computer is restarted, it gave me this message that the bluetooth keyboard was not detectable. Well, I don't have an external keyboard, just the Interior came with the laptop. I have reset the pram and it still does not work. I looked at the system preferences and beach seems to be in check. Is it time to this service or do I still have options?

My Lenovo T61p 6457 has suddenly stopped working.
When I turn it on I see the power and drive green lights HARD turns on and since another computer on my network I can access individual files on the hard drive the T61p.
However when I connect the T61p via a VGA cable for an external monitor to work I don't see Windows or images on the screen!
Do you think it is just a problem with the screen or is there something else?
The screen currently installed on the T61p 6457 is WSXGA 1680 x 1050 (Samsung LTN154P2-LO5).
I found a job WUXGA 1920 x 1200 with inverter and cable in the box of original case Lenovo T61p high - that will work in my T61p?

My hp psc 1350 all-in-one has suddenly stopped working. I can no longer open the software by clicking on the icon in the dock.
Sorry, but I thought that I had reported my all-in-one had started working again. Unfortunately, I can't say what went around, because I don't know. I had only a small part of the way towards what we'll fix me it when he started to work again. I remember that there was a step that I have been unable to finish, and when I asked how to overcome this problem, it started working again. I don't even have the chance to follow the final instructions. I would rather know what was wrong and what are the fixed elements, but I'll have to settle for a working machine.
Ive been using Windows 7 for about 6 months now with on any trouble until recently my DVD drive has suddenly stopped working. Windows detects the drive but when I double click on it in my computer it says please insert disc. I find the drive in Device Manager and windows recognises that there is an error that says:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source. (Code 52)
I tried to uninstall the drivers in Manager device and rebooted the computer to let auto windows find the driver and reinstall it but to start, I get a message that says:
Device not installed driver software
I know that the drive is fine because it works fine in Ubuntu Linux system he worked great in windows 7, so stopped. any help would be greatly appreciated. Thank you.
Go to the Web site of the factory, download the driver appropriate for your device. Uninstall the driver that is currently installed and uninstall the device in Device Manager. Reboot... After you restart, you have 1 of 2 options depending on how the software is packed from the manufacturing. (A) put an end to the automatic Windows installation feature and use the downloaded software to take care of it for you... If that's how it is set up to operate or (b) wait for windows to auto-trouvez and try to install the device, and when he asked the pilots to open and extract files downloaded to any location you choose and point the installer of windows in this direction.

My Windows Live Mail has suddenly stopped working. I get the error message below. I contacted Time Warner - talked to 3 different technicians, each gave different instructions, of which none has solved the problem. I contacted Microsoft and they said that they do not support Windows Live Mail. I am able to access my e-mail through Time Warner Webmail, but I want to get Live Mail works again. Can anyone help?

I don't think it's something that 'suddenly' happened. Does not support the server you connect to SPA, so if you have this option, you will be not be been able to connect to this server. You may have changed the setting to try to solve another problem?

I had CS4 running on my computer for about 4 years. Acrobat 9 Pro has suddenly stopped working. Error message says. "licensing for this product no longer works." Inside the box he is also says, "you can no longer use this program at this time. You must fix to uninstall and reinstall the program or call technical support. However, whenever I install it I get a message that is INSTALLED successfully. Can anyone help me, please.
Thanks John. I did all this and still nothing worked. I finally got help from a stranger (not in the USA) tech of cat. I guess she got hold of me and sent me a link to download this file. Eureka! It worked... Posting it here in case anyone else has this problem. She told me that there is NO SUPPORT for Pro 9 except the forums. I'm happy you're here. Keep up the good work. Here is the page to download the file.
Here is the file that I used that worked for Pro 9 on Windows. Oops, it won't let me attach the file. If anyone knows how I can do make me know.
My Liquify Filter has suddenly stopped working. Any ideas?
Check that you do not have the background show checked and the value of the opacity to 100%.
I have 2010 macbook pro (el capitan) and ASUS H257HU monitor that supports the resolution 2560 x 1440. Until yesterday, I was able to get the full resolution, but suddenly it has stopped working and the max resolution I could get was 1080 p.
I tried to reset the smc and NVRAM, but that did not help.
In safe mode, I followed the suggestion of apple and was able to get resolution of 2560. But it reboots the machine back to 1080 p. Hold down the option key and clicking on the option scale does not display any resolution above 1080 p.
I've tried searching and following some recommendations, but no permits.
Restart the computer and enter views sometimes give 2560 option, but clicking on it makes the screen turns blue and then it always comes back to 1080 p, with no options available in the dialog on the scale. The System Preferences dialog box hangs for a few seconds.
Someone at - he fell on the same issue and found a solution. I don't know why he suddenly stops working, while still being able to work in safe mode but not in normal condition. I tried to remove the profiles as well.
With bootcamp (win 7), the display works fine with 2560 x 1440.
The connector I use is screen Mini DisplayPort.
All proposals/solutions will be very well received.
Hello there, moths.
It seems that you are having problems to select the resolution you want on your external display from ASUS. Great job with the troubleshooting, you've done so far. The following Knowledge Base article offers strong information to look over and review, as well as links to some additional troubleshooting content:
Before you start
You can solve many problems of display by updating the software on your Apple devices, cables and adapters. If you see an image on your screen, look for the software updates using the Mac App Store:
- Connect your external display and Apple video cables or cards that you use with it.
- In the Apple menu, click App Store.
- Click updates in the window of the App Store.
- Install OS X updates or firmware are listed.
If you use a display, hub, extenders or adapter not made by Apple, check with the manufacturer for updates that might be available.
If you try to connect a screen 4 K or Ultra HD TV with your Mac, make sure that your computer meets the requirements for the use of these external displays.
If your firmware and software are up to date, or if you don't see the image on your screen, try the steps below for your specific problem.
Check the connections
Check the connections on your Mac and external screens:
- If you use an Apple laptop computer, try to connect the AC adapter.
- Make sure that the power cable from the external display is connected correctly and that your display is enabled.
- If you are using a Mac Pro (end of 2013), make sure that your screens are plugged into the right ports.
- If you use a hub of display, Cabinet or "KVM", try to connect the video cable from your screen directly to your Mac instead.
- Unplug the video cable where it plugs into your Mac, then reconnect to reinsert the connection.
- If you are using a video card, unplug the video adapter on your Mac, then reconnect to reinsert the connection.
- If you use multiple video cards to connect your screen (the cards are "chained"), testing connection of the screen by using a single adapter if possible. Some video cards may not be linked together. For example, a mini DisplayPort to DVI adapter may not be connected to an adapter DVI to HDMI.
- If your screen has more than one video connection, see if you are using another connection on the display works. If possible, check if you use a different view or a different adapter works.
- Try using another cable that you know to be in working condition. Check with the manufacturer of the screen to make sure that you use the cable they recommend.
Detect your display
If you use an external monitor, sleep and wake your Mac to check for connected screens:
- Press the power button on your computer to standby, or choose the Apple menu > sleep.
- Wait a few moments, and then press a key on your keyboard or click your mouse or trackpad to wake up your Mac.
If you use more than one screen, and you can see the image on one of the screens, you can also use the preferences monitors to check the connected screens.
Adjust video settings
If there is no image on the screen, try adjusting the brightness or contrast of the screen. If there is still no picture or image appears torn, or scrambled, try selecting a different video resolution in system preferences. Adjust brightness
- If you use an Apple Display Monitor, press the key to increase brightness your Apple keyboard. To adjust the brightness of a secondary screen, press Control + F2.
- If you use a view that is not made by Apple, see the documentation that came with your monitor to see if it includes built-in controls to adjust the brightness or contrast.
Change your display resolution
- In the Apple menu, choose System Preferences.
- Click the display icon.
- Click default for display. If you see more than one resolution listed, choose a resolution and refresh rate. If the display turns off when you change resolutions, press the ESC key to cancel the change.
If you can not change the resolution of your screen because you see no image, restart your Mac in safe mode to reset the default display resolution.
Search for software third display
If your monitor only works when your Mac is started in safe mode, and related to the software display is installed, check with the developer of the software for updates, or try to uninstall temporarily.
Get more help
If you have tried these steps and your screen still does not work, contact the Apple support for more help.
