Apple TV Airplay Black Screen and minimum display options

I recently got an Apple TV (4) and when I activate Airplay, the HDTV shows just a black, when streaming to my iMac screen (end of 2013). The audio works well when the iMac iTunes app streaming, but not the screen. Airtime in my Apple menu options appear to be incomplete.

AirPlay however works PERFECT on a new Mac Mini. I can see all the options you would normally see in the Apple menu and display preferences. Wifi networks are all the same.

Once connected to the Mac Mini, I see it in the menu bar options

Once connected on the iMac, I see it in the menu bar options

Furthermore, I recently deleted, Duo & display menu of my iMac but also completely disabled the firewall. After you remove the app and all the library files (that I could find), I closed my iMac. From the start I have reset the PRAM, just in case.

Result... I do not have any option to extend my screen and all I get on my Apple TV4 is a black screen with text.

Which party 3rd software are know because of conflicts with AirPlay? This seems to be the only logical cause of the black screen. I had, Menu display, Air Parrot, Duet, on previous machines there for years and I can have hidden conflict with AirPlay on the current iMac, I use library files.

The problem has been resolved. I found the solution on another site. I copy here and share the link.

And the solution is in the comments. Parrot air extensions are the problem... I tried Air Parrot for like a day and then uninstalled, but I or clean my Mac missed parts.

RS http://9to5mac.com/2014/02/28/OS-x-...tensions-to-External-Monitors-for-some-use.

Here is the fix:

1. open a Terminal in Applications/Utilities.

2. run these commands respectively:

sudo rm - rf /System/Library/Extensions/APExtFramebuffer.kext

sudo rm - rf /System/Library/Extensions/AirParrotDriver.kext

sudo rm - rf /Library/Extensions/APExtFramebuffer.kext

sudo rm - rf /Library/Extensions/AirParrotDriver.kext

This allows to uninstall the kernel extensions associated with AirParrot. Other solutions on the web are displayed are missing extensions in/Library/Extensions.

3. Enter your administrative password when you are prompted.

4 restart your computer.

  • Satellite Pro L450D black screen and will not respond to any keys

    Hello

    My niece has used his Toshiba L450D for almost a year now and he really liked it, who was until last month. She turned on her laptop and when she presses the button of the mouse, the button cracked and he fell into the laptop.

    Now my brother contacted Toshiba and I was told because it is under warranty it might return for repair because it was a common fault. Then he he packed in loads of air bubbles and a box to make sure it was safe.

    A few weeks later he came back repaired but we were all shocked that the laptop was put in a very loose box and you could hear this rattling noise. When we turned on the battery was flat and we had a new boot menu.

    As she installed it Windows 7 laptop would boot directly into Windows 7, but now after the repair of the laptop shows a menu black screen with as follows:

    + Windows 7 +.
    + Recover Windows to Factory Settings [active EMS] +.

    So we started in Windows and everything went well, but now after 5 or 10 or even 20 minutes, laptop displays a black screen and will not respond to keys or mouse movement. There is nothing on the screen its just black.

    I started in SafeMode (which was more difficult with the new menu) and it does the same thing. I even managed to do a virus scan quick who took 3-4 minutes and was clean.

    I would like some advice on what my niece is very angry, and it's difficult to explain what is happening to a child in the primary school.

    Any help would be grateful.

  • After logging on my Satellite Pro only black screen and the cursor are visible

    I have a windows vista pro (PSAASE-00G004GR) satellite after turn on and typing the password for windows vista, the screen goes black but I see that the cursor moves & because it seems that the hard drive also works in th background, but I can't see anything except the mouse cursor , I tried to boor with other options (LAST WORK safe MODE KNOWN FEATURES... etc) but it's still the same only black screen and the cursor...

    I do not prefer the product cause of my data recovery on this subject, any ideas?
    thnx

    Hello

    You have the Satellite Pro A100 PSAAS hmm if you want to save your personal data, I recommend to remove the portable computer HARD drive and try connecting it to another computer via an external USB HDD controller. These cases of 2.5 HARD disk are not expensive and you can buy it in every store of the computer.

    Then you could try to recover the laptop delivered together with the Toshiba Recovery CD.
    But wait; have you tried to connect the laptop to the external display?
    Check it!
    Maybe you could see something on the second screen.

    I think that this procedure could be useful to clarify what s wrong.
    To me this question looks like a small little dysfunction of the FL inverter.
    In this case the installation of the new operating system will help you not to solve this problem.

    But who knows the verification is necessary to find what could be wrong.

    Good luck and bye ;)

  • Start the computer to black screen and the computer runs hot

    original title: sick Vista laptop

    My daughter portable computer began acting strangely very yesterday.

    Once connected, I get a black screen and a cursor.  The system seems to work at full speed, because I can hear the fan, and it runs very hot.  No matter how long it sits, the desktop does not appear.

    I can use Ctrl-alt-del to display the Task Manager.  The list of processes is limited to the process of the current user, and none of them use important CPU. If I click on 'See the process for all users', taskmanager freezes and I have to disconnect to get rid of him.

    Using the Task Manager, I can kill the process Explorer and then start it again, date at which I get my desktop.  However, it is still running hot and noisy.  With the help of SysInternals ProcessExplorer, there is no process using any important CPU.  Most of the time CPU is reported as inactive.

    I don't know what to think.  A boot loader took over the system?  A hardware problem?  OS corrupted files?

     

    Follow these steps to try to solve your problems of boot.

    If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

  • Windows 8 black screen and the cursor after the connection

    Hello. I tried to upgrade to 8.1 Windows 8 Windows and it is stuck on like 3% for one hour, so I just rebooted the computer and he returned to Windows 8. I'm going to sleep and come back the next day and go on my laptop and it auto connects me and it goes to a black screen and I only have the slider on the black screen after login. I don't see the start menu, but I receive notifications for as sticky keys or any other notifications lights. I turned off my computer at least 20 times, took out the battery, empty the battery and tried to boot in safe mode with no luck. It is unlikely that it is an internal problem, because if I leave my computer alone for a few minutes, my screen saver photos appear. If anyone can help me solve this problem or help me get in easier safe mode would make things less stressful. I have an Acer Aspire V5 - 571 series. Thank you.

    Everyone everyone please help!

  • Satellite A210 - 11 p - gos black screen and HARD drive does not

    Hello

    My Satellite A210 - 11 p suddenly goes to a black screen and the hard drive stops working. It is always under tension and if I want to restart I have to unplug the unit and remove the battery.

    I thought it was overheating and checked the time and they were really high in the 1980s. I took the fan and cleaned (very dusty) and the basic form of thermal paste. Temperatures plummeted now immediately but I still have the same problem, I updated the graphics driver and watched the temp on GPU (which is fine) but the problem is still happening. I used a number of programs to check for errors on the hard drive and no reported problems. I reloaded Windows 7 but still no joy.
    The problem seems to occur at any time and is not due to the execution of a given program, even just browsing with firefox

    Not too sure what to do and any advice would be welcome.

    Hey Buddy,

    > I reloaded Windows 7 but still no joy.
    Have you ever tried with Toshiba Recovery disk operating system?

    The Toshiba recovery disc there is an image of the settings from the factory with all the drivers and tools. If you install Windows on this disk, you factory back.

    That would mean if you have the same problem after the installation of recovery it s really bad hardware working because you have pretested settings of Toshiba. In this case an authorized service provider can help you make an accurate diagnosis what part is affected.
