After Upgrading to 10.9.2 Isight is not working

Uninstalling/Deleting Splashtop Streamer and rebooting fixed the problem for me.

I have been using Macs since 1996. Those who are as old as I am will likely remember Conflict Catcher, and rebooting several times to find a conflicting extension or control panel under Mac OS 7.

Deaj Vu feelings 🙂

I have read this entire thread and I am coming back every other day hoping to see a reasonable solution for this. For me, so far the best solution still is waiting for OSX 10.9.3. I used to have AirParrot and AirDisplay installed and I have uninstalled both. As this problem is affecting only my Macbook Pro Santa Rosa (Macbook 3,1, pre-unibody, late 2007), I can still use my Macbook Air camera.

I will not mess around unless 10.9.3 does not fix it.

Thanks enr0gue. AirParrot was the problem on my MacBook Pro. I removed the the drivers with these commands and iSight works again:

For Macs running OS X 10.6, the following commands can be run from the terminal:

• sudo rm -rf /System/Library/Extensions/APExtFramebuffer.kext
• sudo rm -rf /System/Library/Extensions/AirParrotDriver.kext
• sudo rm -rf ~/Library/Preferences/com.squirrels.AirParrot.plist
• sudo rm -rf /Applications/AirParrot.app

For users using OS X 10.9, the following additional commands may be necessary:

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

Restart once you've removed the drivers.

Well after having sifted through all the advice here (it is all very helpful) I bit the bullet and removed all the "not signed" kext from my system (really just copied them to a temp directory. This was after verifying that my camera worked fine on my MBP in safe mode. And what to my wondering eyes should appear, but that everything worked perfectly. I had some very old kext and removing them was probably long over due. So if you want to fix the problem take the time to remove these old kext and your system will be good as new.

Thanks again for all the terrific help in this post.

i remember CC! kkk those were more than 15yra ago, my my.

i wonder my old iSight FW cam would work or crash.. hmm ;)

Reset your computer’s PRAM

No. This issue demonstrably and reproducibly has nothing to do with PRAM. The cause and solution have already been identified. Please don't add useless instructions.

This worked for me.... 🙂

Then it was a different cause unrelated to the 10.9.2 update.

+1 Pram re-set seems to have solved my problem.

I discovered when trying to use google video/chat, kept on asking me to downlaod plugin for chrome, which i did several times, which didn't work, then found a post to check if the plugin was enabled, which it wasn't;

view chrome://plugins/ to check....still no joy.....

tried skype which had been working and video didn't work on that either, as unable to access iSight, so started looking in Apple forums.....and found my way here.....

....and a solution...🙂

Big THX Frederic Cote1. You are a genius. Worked perfectly on my MBP 4.1.

Hei support

This is the response from AirDisplay ==>>>

Hello,

My apologies for this issue. It's a bug we are aware of. It stems from an issue with OS X. Certain Macs that have a third party video driver installed will exhibit this issue. So, it's not just Air Display that causes this problem but other apps like Display Link, AirParrot, etc. will also have this issue. Apple has contacted us regarding the problem and they're looking into it. It's not actually something we or those other third party developers can fix. Apple has to address the issue with OS X. Hopefully they'll fix it soon.

wlgspotter, thanx a million. I've been experimenting with my iPad as a second display and tested a bunch of apps, and totally forgot about Splashtop. I've deleted it a long ago, but it SR*.kext still were in /System/Library/Extensions. You rock!

Glad to know if helped your case @chatzki.

I think the general consensus here is that it is confirmed there will be issues with applications that install and need to access the video capabilities, just that there are a lot of such apps, so I'm sure there are bound to be a few not mentioned/encountered. A few notable ones had already need mentioned (I.e. Air Parrot), and any other people who managed to solve their problems and listing down their experiences will help. :)
