Air Drop and the iMac
I have 3 Macs. Air Drop appears on and functions on two of them - the MacBook Air and the Powerbook. But Air Drop does not appear at all on the iMac. It is not to be found in Finder nor through a search. Why might this be?
That's a kernel panic and indicates some sort of problem either with the computer's hardware or software. Visit The XLab FAQs and read the FAQ on diagnosing kernel panics. It would help to post the panic log: Mac OS X- How to log a kernel panic.
Meanwhile, try booting the computers into Safe Mode then restarting normally. If this is simply a disk repair or cache file problem then this may fix it.
You can also try creating a new admin account on each computer then booting into the new account. This would help determine if the problem is related to a bad file in the user accounts.

I recently bought two iMac quad core i5 processor speed 2.5 Ghz. Every time I use Air Drop and I send a file from one iMac to the other, a black curtain drops and I am asked to restart the computer!!! What can I do?

I would like to copy my iPhoto (9.4.1) library from my Mac Pro (10.7.5) to a Macbook Pro (10.7.5). Can I drag the iPhoto Library from the Pictures folder to Air Drop and send them to the MacBook? If I then move that to the Pictures folder on the MacBook will that then be a usable iPhoto library on the Macbook?
It would be better if you could connect the two Macs via a hard wired LAN to copy the library from the Mac Pro to the MacBook. Wireless connections can have momentary dropouts which could affect the reliable copying of files.
If you do go with Air Drop be sure to open and inspect the copied library closely to confirm it was a successulf copy.

What exactly is Air Drop and Air Play?
I keep seeing these cutely coined phrases such as Air Drop and Air Play but I can't find a full explanation as to what they are and how to use them. Can anyone direct me to a source where these are explained in detail?
AirDrop is a OS X feature that allows you to transfer files wirelessly through different Macs with OS X Lion or Mountain Lion and connected to the same network. This will be available in iOS 7 for some iPhones, iPods touch and iPads.
AirPlay is a system that allows you to sync music, videos, or simply your iOS or Mac desktop to an AirPort Express, AirPlay-compatible speakers or an Apple TV. Read > http://support.apple.com/kb/ht4437 -
Air Drop and File Sharing Between Macs Please HELP
I have a 2011 Mac Book Pro running Mavericks and a 2010 Mac Pro running mountain lion and I am having trouble air Dropping and file sharing between them.
My MBP works fine. It can see other macs and share with them on my home network. My MP on the other hand cant see any other computers under the shared devices location in my finder. I have turned on file sharing for my MP as well as screen sharing. Neither works. My Mp used to be able to Air Drop and File share.
When I try to Air Drop to my MP it wont receive the item.
Has someone been through this before and know how to fix the issue? Ive been trying to research this for a while and haven't been able to find a solution.
Any help would be great!
ThanksAre you using a frieWall on individual Macs?
If you are using a Router you control, individual computer FireWalls are not needed. -
Air Drop and Air Play incompatible
Cannot get air play on my phone and it insists on placing air drop where the icon for air play should be.
Air Play is on the same Wi-fi network and works still from my computer on the network I phone sometimes shares the airplay icon with the airdrop but sometimes it doesn't. right now it is not on my 5c or on my wife's 4s. we automatically updated to 7.1.2 and that's all she wrote.

Error message: ni: A frame has been dropped and the acqusition has been canceled
I use a NI PCIe 1433 framegrabber with a Basler spl4096-140km line camera.
Using triggered acqusition with an external source, I can get a framerate of 68500Hz in NI-MAX.
When I use the Matlab image acquisiton toolbox to acquire data, I however very often get the error message: 'ni: A frame has been dropped and the acqusition has been canceled". This happens even at much lower framerates (20kHz) and only seems to go away when acquiring data slowly.
Computer is a Dell Precision 7600 and I assume there should be no issues with RAM or the PC being slow. The error does not go away when reducing the data size (i.e. reducing the ROI to one single point that is readout).
Do you have any pointers why this error message appears and what can be done about it?
Thank you!
RetoHello,
I encountered the same problem and I think it is because the allowcation of storage in matlab cannot catch up with that of the camera so that it will drop frames when the buffer is full.
I also want to know how to solve that.

Strange IMAQ Error Message: "ni: A frame has been dropped and the acquisition has been canceled."
Hello,
I am getting a strange error trying to use the NI PCIe-1427 with the MATLAB image acquisition toolbox configured with continuous acquisition. After about 5 minutes of acquisition, I get the error below:
??? ni: A frame has been dropped and the acquisition has been canceled.
Does anyone have any clues as to why I am getting this error / where I can find out what causes it? I need to acquire several hours worth of data and this error completely aborts my acquisition.
--YHello,
Turns out that I found the problem. I had a slow memory allocation in my MATLAB code and this delay allowed too many frames to be accumulated in memory. I still do not know the source of the exact text of the error, but upon removing the slow memory allocation the error no longer occurs. I believe that it may have resulted from a buffer overrun of some sort in the underlying driver.
Given that this no longer poses a problem for me, I will not pursue it further.
Thank you for your help! -

Can time capsule back up an external hard drive attached to my imac and the iMac internal Harddrive
In addition to Kappy's comments, the external drive must be formatted in Mac OS Extended (Journaled) in order for Time Machine to be able to back it up.

Is it possible to mirror the display on the Macbook pro which is two years old to my iMac which is four years old? Macbook pro is running OS X Lion 10.7.5 and the iMac is running OS X 10.6.8 (10K549). Neither of them have Thunderbolt ports.
OK, well I would go with what Apple says in writing but if you want to take a trip to visit the Genius Bar that won't hurt.
Good luck, I'm 99% certain you will find I was correct but please let us know.

TS3274 I have an iPad 2 that was dropped and the glass broke.
I have an iPad 2 that was dropped and the glass broke around Christmas break. I took it to a local computer repair company and they changed the glass. However, ever since that time I have had some problems with the wifi. I do not have the range I once had? For example I can walk out of the room that my verizon jetpack is in and loose connection. I have also had issues with my Keynote presentations loosing connectivity to Apple TV through the blue tooth. Q What are my options beside getting a new iPad?
Some iPad users have been able to revive their dropped iPad. Turn the iPad over and give it a HARD SLAP on the back. May take several slaps.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
• Launch Settings app
• Tap on Wi-Fi
• Tap on the blue arrow of the Wi-Fi network that you connect to from the list
• In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

A third-party place like maybe less. Google for one near you.

Loving Air 3 and the Captive Runtime
I just wanted to pass on a huge kudos to the Air team. We just released our first product (a free iOS Web Simulator for Windows) built using Air 3 and the captive runtime (release version). Tons of downloads, and not one singe report of an installation issue. I know the captive runtime isn't a panacea, but being able to whip out a simple install script, and an exe/app with no dependenices and some determinism regarding the runtime is very nice indeed for our use case.
I made sure to put a "Built with Air 3" link on our download page too

Really looking forward to Flex 4.6 as well, good time to be an Adobe dev!
Thanks again.

new airport: can't get my macbook or my imac to join my wireless automatically, my other stuff still joins without problems but i have to join manually with the book and the imac ?? I've tried all the settings and every thing else I can think of.....
Running on Lion, never had a problem before until the old airport died and I replaced it.try connecting the device in _*recovery mode*_, then restore from your backup.
also, make sure [_*Apple Mobile Device Service*_|http://support.apple.com/kb/TS1567] is installed and started.

Between the Imac 2.7 I5 and the Imac 3.4 I7...
I'm in between the Imac 2.7 I5 and the Imac 3.4 I7. I know there's a $500 difference so I'm trying to see if I really need that much power. I do mostly audio stuff with Digital Performer and Native Instruments Komplete which streams instruments. I'm also going to boost the RAM to 16GB. I'm mainly worried about glitching. I want to make sure that when I run photoshop and Final Cut Express that I won't have a problem with the 2.7 i5. Will it be fast enough? $500 is a lot of money for power that I may or may not use and would rather spend it on software upgrades if I truely don't need the fastest Imac. What is your opinion?
