Airplay from iMac dropping....

My 2011 iMac drops the airplay signal every 10-20 seconds. Airplay from my iphone & ipad work fine with no dropping so the problem is definitley related to the imac and not my wirless connection. I reset the pram & smc, this made no difference. I deleted the airport file in library-prefences-system configuraion, and this solves the problem for a while but then it returns within 24 hours. I can see by looking at the wireless status that it drops the signal everytime the imac searches for new netorks which is every few seconds. This is driving me mad, please someone help?!!!

Have you tried to change the channel on your WiFi router/access point?

Error (-42018) when trying to airplay from iMac to iPad2

When trying to airplay from itunes on my iMac to my new iPad2, it starts ... connecting... and gives me the error
"An error occurred while ... unknown error (-42018)."
Anyone know what that mean? They are on the same network and I can pick the ipad to from the "play on list."
Thanks in advance

No, I am not wrong but thanks for playing.
You need to install airframe
Perhaps you could have mentioned this in your first post because it is not a standard part of AirPlay.
Please don't answer questions, when you don't know the answer.
I do know the answer which is why I responded (though now I wonder why I did).
You should contact the author of Airframe instead of being rude.
and it does not seem to be in the (US) App store anymore.

Music videos won't airplay from imac to apple tv all other content including movies will???

title say it all, cheers

I think it's something to do with playing to multiple sources from imac (imac + apple tv) songs work fine but when a music video comes on it switches to imac only and cant then be sent to apple tv without first disabling multiple sources.

Airport Express streams Airplay from iMac but not from Windows 7 PC

I have a wireless network set up using a Linksys WRT45G2 v1 router. There is one iMac running Snow Leopard, one laptop running 32 bit Windows 7 Ultimate and one desktop running 64 bit Windows 7 Ultimate. The router is set to WPA2 Personal TKIP+AES security. The Airport Express is set to WPA2 Personal. Its wireless mode is "join a wireless network." It is running firmware version 6.3. The iMac and the laptop are running iTunes 9 and the desktop is running iTunes 10.
Up until recently I was able to stream music from the iMac and the desktop but not the laptop to remote speakers using airtunes via the airport express. Then the video processor in my desktop PC failed and in the course of diagnostic testing I had to reinstall the OS. After replacing the video card and reinstalling the OS, I tried to reconnect Airport Express to iTunes on the desktop PC but Airport Utility could not find the Airport Express. I returned the Airport Express to factory settings and tried again. The PC still did not recognize the Airport Express. I couldn't use the PC to reconfigure the Airport Express, but the iMac did see it so I reconfigured the Airport Express using the iMac. Now I can stream music using Airport Express from the iMac ONLY.
When I use the Airport Utility to scan on the desktop or the laptop PCs it does not see the Airport Express. I can, however, see the Airport Express and read its configuration using Airport Utility on both PCs by using "configure other..." under the File tab (i.e. by typing in the IP number and password for the Airport Express.) Even though I can read the configuration and save it, iTunes does not recognize any remote speakers and I cannot stream music from either PC.
I have tried turning off ALL wireless security as well as all firewalls. I also tried both iTunes 9 and iTunes 10 on the desktop. Nothing makes any difference.
Before I could at least stream from desktop even though I had never been able to get the laptop to stream.
Can anyone suggest a way to get Airtunes (Airplay) to work from my PCs?

I have had the same issue. Airplay working with all devices apart from one windows 7 (the actual media server) and have spent over a week trying to resolve it.
This worked for me.
Turn off windows firewall and in my instance macafee. Be warned while macafee says that it's off there are services running all the time.
You will need to open macafee settings and turn off access protection first
Then search services from start bar
Open services and filter by manufacturer
Stoop all macafee services
Right click the start bar
Open task manager
Stop all macafee processes
Try your airport utility you should now see your express
If you can you will see your icon in iTunes
This pores that it's likely to be a macafee issues. Of course you do not want to leave the firewall off so I installed macafee and installed a fresh copy turning both the windows and macafee firewall on with no resultant issues
Hope this helps

Why can I no longer Airplay from iMac?

I have a 2011 iMac and a 2012 Mac mini. Today my iMac will not airplay, no airplay option. I get "Superdrive F12" when I click on airplay. Display settings will not show airplay. Yes, same wifi network.
Stumped???

Airplay from iMac to AppleTV will only share video, no audio.

I am on Mountain Lion on my iMac, with a new AppleTV. Sometimes screenshare will work, sometimes it will only share video. I can't figure out why it happens, going into Sys Prefs won't let me select audio for AppleTV.

Can you select Apple TV as audio BEFORE you start the mirroring, this is often the problem.

I had airplay working fine from imac to apple TV. Just bought an iphone 5s, now it works very badly with both devices. Why?

Airplay from the imac was working fine, adding an iphone 5s to the set-up seems to have led to it not working properly from either device - it skips sections and then drops the connection. Any idea how to fix?

Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device.

HT201343 can i turn off my imac monitor while airplay from it to my tv?

can i turn off my imac monitor while airplay from it to my tv?

You can just turn your brightness down to 0. Only thing I have figured out so far.

Apple TV3 doesn't start automatically when i select airplay from my iMac and Ipad 3. i have to manually turn it on then it works fine after that! what is wrong with which setting.

Apple TV3 doesn't start automatically when I select airplay from my iMac (Yosemite) and Ipad 3( iOS 8.1.3) i have to manually turn it on then it works fine after that! what is wrong with which setting.

You need to re install OSX. If you have the dmg file downloaded via torrentz this is how you can create a bootable external HD or Flash drive (8 GB+)

I am trying to use airplay from my iMac but the airplay symbol has disappeared?

I am trying to use airplay from my iMac but the airplay symbol has disappeared. It works perfectly well from my iPhone and iPad and tt did work for a while from the iMac allowing me to select multiple speakers including Apple TV and my two panasonic stereo systems which are airplay compatible, but now only works from iPhone/iPad. Any guidance would be appreciated.

I as having a similar problem with the iOS remote application. I was trying to stream my iMac's media to my Apple TV, but the iMac would not show up as a choice. This was particularly frustrating because I have updated in the last to weeks to 1.) The Yosemite Beta on my iMac, 2.) New sotware on my ATV, and 3.) iOS8 on my phone. It was impossible to ascertain which of those three updates was the culprit. So after much troubleshooting (and much swearing), the following seemed to work:
One-by-one, disengage home sharing on all three devices and then re-engage. Pretty simple. Let us know if it works for you!

Was watching a movie with AirPlay mirroring on apple tv from iMac. Got a Skype call. Turned off AirPlay on atv and on iMac. Could not hear my Skype caller until I unplugged the atv. What else could I have done?

I checked and found that the router did not have the latest firmware.   It does now.   The issue is still there.   I did a little research and found that the model number of my Apple TV (MC572LL/A) shows that it is a 2G version which uses the A4 chip.   The latest version uses the A5 chip and is 1080 capable. Both are supposed to be capable of using type "N" routers.   I don't think that should be an issue but I wonder if later updates may have introduced some issues in the 2G version.
I am going to try changing the "N" channel also- just to see if that makes any difference. The istumbler app does not show any "N" networks in my area so it is defaulting to 149.   I will note that even 1 foot away from the router I only get 75-85% for signal.   I would expect it to be 100% since it is so close.   I am also seeing noise go up from typically 13% to 21% when it is on channel 3 and that close.       I will play change locations and channels and see if there is any improvement.

Mavericks has broken Airplay from iOS 7 iMac

When I had iOS 6/7 on my iPad and iPhone, I could use Airplay from my iPad or iPhone to my iMac, no problem.
Since updating to OS X Mavericks, I can Airplay from all of these devices to Apple TV, but not from either iOS device to my iMac (which is late 2011, so this should be possible). It worked that way prior to upgrading.
Anyone having the same problem? Any solutions?
Thanks in advance.

What exactly happens when you try to update it? If you're getting an error message, you have to tell us what it is. We are not psychic.

Youtube airplay on ATV dropped from iPhone

When using Airplay to watch a YouTube video from my iPhone 5 on my AppleTV 2, anytime, I switched to Messages, Email, or any other program on my iPhone, YouTube stops playing on my Apple TV. This is a new issue. It hadn't happened in the past when I could surf the internet, send messages, etc. while using Airplay to send videos to my AppleTV.
Is anybody experiencing the same problem?
Thanks!

...a little more experimentation...
I booted the MBP 15 (Spring 2011) from an external backup of Lion (made immediately prior to switching to ML). When I turn off the Server Firewall then I can iTunes Airplay to both the Apple TV as well as to the Airport Express. But when I turn on the Server Firewall, even after allowing ports 3689, 42000-42999 both TCP and UDP, the Airplay does not work. I could not determine which ports were needed for iTunes Airplay, all I could figure out is that when the Server Firewall is off then iTunes Airplay works but when the Server Firewall is on then iTunes Airplay does not work. I tried logging all denied packets, but to no avail, I still could not determine which ones were being denied.
Interestingly, when I turn off the Server Firewall and switch on the System Preference Security pane Firewall, I can still iTunes Airplay to both the ATV and AX. It makes me wonder if when I switched to ML from Lion that some ipfw rules were not left over from the Lion Server Firewall that then keeps ML from allowing iTunes Airplay to work. (I wonder if I restore my Lion Server, then switch off the Lion Server Firewall, then download and install ML once again, then download and install OS X Server once again, whether the iTunes Airplay would then work? Maybe when I have some more time I'll try this, in the meantime I'm going to try a little harder to figure out why the Lion Server Firewall stops iTunes Airplay from working. Dang nabbit, even "ipfw show" does not tell me which packets are being denied when the Server Firewall is ON and iTunes Airplay does not work...does anyone have any suggestions on how to figure out why the Server Firewall is stopping iTunes Airplay from working?)
Thanks,
Switon

Conflict between home sharing from MacBook Pro and airplay from ipad / iPhone?

Just bought an Apple TV, and set it up yesterday. Everything works fine, with one exception. When I have iTunes open and home sharing turned on the Apple TV, when trying to mirror airplay from my ipad 4th gen or my iPhone 5s, I get nothing on the Apple TV, just black screen. It also makes the device run really sluggish.
I've definitely narrowed it down to this conflict, quitting iTunes on the MacBook Pro immediately resolves the issue. So no big deal, right? Just turn off itunes. Except the whole point of buying the Apple TV is to have a central point I can stream all my media in the house from, I'd like to have my MacBook Pro, iMac, ipad and iPhone able to take control of the Apple TV without having to run across the house to turn iTunes on or off on the computers.
This only happens when mirroring, normal airplay audio or video works just fine. MacBook Pro and Apple TV are hard wired Ethernet, ipad on wifi.
Is this a known conflict? Is there any solution?

Normally there ought to be an airplay button in the top menu bar (where also the battery, wifi, clock, etc are located). And in display settings at the bottom there ought to be a drop down menu labelled Airplay Display.
If not, it seems that your Apple TV cannot be found. Are both on the same network? Have you enabled AirPlay in the Apple TV (Settings -> AirPlay set to On)?

How to export photos from iMac to iPad.

I have a 3 year old iMac & iPad 4. I have read the discussions and the very limited iPad manual. These pictures are in my iMac not on an SD card or in my camera. They were imported to my iMac from a CD. I read about syncing and starting iTunes etc. I need STEPS & what device you start iTunes on etc. None of the discussions state this. So getting my pics from my iMac to iPad I need to do .........? Thanks

Connect the iPad to the Mac and launch iTunes.
Click on the iPad name on the left side under the devices heading
Click on the Photos Tab on the right.
Click on "Sync Photos from" and then select the folder where your pictures are located - usually on the Mac in iPhoto. However, you can choose any folder from the drop down menu in the Sync Photos From heading that you want to use.
Click on any albums within that main photos folder that you want to sync.
Click on Apply in the lower right corner of iTunes
If all of your photos are in one folder on the Mac, you will not have any sub folders to sync.
