Macbook Air thunderbolt ethernet not working after 10.8.3 update

Hi,
Thunderbolt Ethernet for my Macbook Air (11-inch, Mid 2012) stopped working after installing 10.8.3 update. I am unable to conect to my router via thunderbolt Ethernet connection port.
Anyone else having the same issue? Any recommendations?

Unplug your thunderbolt adapter. Restart the router.
Go to your Mac and go to System Preferences >> Network
Use the - button in the lower left corner to delete your Thunderbolt to Ethernet adapter.
Now plug your thunderbolt adapter back in and use the + button to add "Ethernet Thunderbolt" to your list of connections. Move it back up in the order of network preference you want.
Your network access should now be reset.

Thunderbolt ethernet not working after upgrading to Yosemite

After a very long and frustrating 2 days I have managed to upgrade my MacBook Air (13 Inch, Early 2014) to Yosemite. I have the official Apple thunderbolt to ethernet adapter but System Preferences/Network reports that the cable has been disconnected. It has not and other devices connected to the ethernet cable work fine. Any suggestions to get it working? Anyone else having the same problem?

I have a similar problem. My Macbook Pro Retina 15" (1st generation) can no longer connect to my university network through a Thunderbolt-to-Ethernet adapter since upgrading to Yosemite. (Actually, OSX 10.9 on a different machine altogether also has the same problem -- tested and verified.) I tried multiple dongles and multiple Ethernet cables, and finally called our tech support. We found a workaround for the problem by purchasing a USB to Ethernet adapter, but this now means that instead of a single device chain leading into the laptop, I am now using multiple ports. I hope a patch for this is in the works.

Thunderbolt Ethernet not working after Yosemite upgrade

Upgraded last night to 10.10, and now my Thunderbolt Ethernet adapter has no MAC address, and my MBP appears to think the cable is unplugged - it's not, and worked fine when the MBP was running 10.9 yesterday. Things which haven't worked:
Deleting and re-adding via Network Preferences
Changing default IPv6 to Link-local only
Rebooting with the thunderbolt adapter in
Rebooting with the thunderbolt adapter not in
Switching the thunderbolt adapter to the port further from the hinge and back again
Unplugging and replugging the ethernet cable
Plugging the ethernet cable directly into the wall jack instead of the hub it has always been plugged into
Unplugging and replugging the Thunderbolt
Changing Location to "Work" from "Automatic" and back again

...but these seem to be all 3rd party USB ethernet adapters and nothing to do with the Thunderbolt adapter of the thread - or am I missing something?
I have the same blooming problem, it seems to be totally hit and miss whether the adapter works or not.
I thought is was a faulty adapter, so even bought a second one for my MacBook Pro, so a bit more profit for the most profitable company in the world for a non working device. My ethernet cable works fine to an old apple USB adapter but is 90% useless with Thunderbolt.
Renewing the DHCP lease occasionally works, but totally unreliable, at the moment it fails.
Still looking for a reliable solution.
Come on Apple, please sort this out, you have a connector policy of turning everything you can into adapters and dongles rather than building them in, so you end up with a slim laptop and a bag of adapters to carry around, and then when they don't even work - doubly annoying.

HT1338 early 2012 macbook air clamshell mode not working after mountain lion update

Can't make 2012 MBA 13" work in clamshell mode after updating to Mountain Lion. All peripheral devices are connected, as is AC power. Closing lid causes external monitor to enter sleep mode (presumably, the MBA is going to sleep as well).
Power settings are set to stay awake when on AC power.
Thank you.

Hi,
The two may be linked as there is a common support app called IMAgent that helps with both Messages and FaceTime.
Shut down both apps.
With the Finder as the Front App > use the Go Menu > Hold down ALT key and select Library.
In the Library find and open th Preferences Folder
Find com.apple.IMAgent.plist and drag it to the Trash
Before restarting the App now go to Activity Monitor in Applications/Utilities.
Find imagent (it is in lower case).
Highlight and use the Quit button.
Now restart the app(s).
This will recreate the .plist from defaults.

MacBook Air Camera is not connected after mac OS update

MacBook Air Camera is not connected after mac update
I have a MacBook Air OS X version - 10.9.4 . I updated my mac 1 week before but todayI check that my mac in built camera is not working Even I try to check in this thing in all the apps. Please provide the way how to sort out this issue asap.

The SMC reset often fixes your problem.
Be sure you follow the instructions for your particular Mac model.
If your problem continues, restart Mac. Then download and install OS X Mavericks 10.9.4 Update (Combo).
If that does not correct the problem, reinstall Mac OS X.
If nothing else works, contact your Apple Service provider or Apple MacBook Support for help.

Thunderbolt ethernet not working when computer wake up from sleep.

thunderbolt ethernet not working when computer wake up from sleep.
it will not happen in Mountain loin.

I had this problem on SL and on Lion as well, and it occures for WiFi and Ethernet connections.
In fact the internet connection was not broken as I could ping the destination usin the IP (not DNS name).
In this case the problem was related to mDNSResponder task which handles all dns queries.
It was the most frequent problem in my day to day work with SL and now Lion. It was never fixed by any patch from Apple. I tried almost all voodoo including fresh install, all possible config changes - no solution.
The only version with no problems related to network was 10.5.8. All the other versions had issues of different kind (WiFi instability (lost signal), DNS problems (for wireless and wired connection) sometimes associated with machine sleep and wake up and sometimes with no reason.
QUESTION: Is your problem independent of the access point / router you connect to.
I must say networking was (and still is) the weakest part, besides the other OS X weaknesses I experienced during 4 years of OS X usage.
No problems in the same network with Linux or Windows beeing ran natively on my iMac So hardware is OK.
Software is of poor quality. Not much more to say in this matter.
I found a very interesting article dated 1996 about programming which I think is still valid.

HT2090 my macbook air camera is not working

My Macbook Air camera is not working when I try to use photobooth. I have no problem with google hangouts or skype. How can I resolve this problem?

• Restart your Mac. If the problem continues, use the Disk Utility in your Mac's Finder > Go > Utilities folder to repair permissions. Then test the camera again.
• If the your trouble persists,. reinstall OS X Mavericks. Repair permissions again immediately following the restart that completes the reinstall and before testing the camera again.
• Also check your Mac's  > Software Update... or Apple - Support - Downloads for latest Mavericks updates applicable to your Mac model such as OS X Mavericks 10.9.1 Update.

Macbook Air HDMI adapter not working

I know there are other threads about this but they are a bit outdated. So anyway I bought an hdmi adapter for my macbook air and it was working perfectly for about an hour and a half when suddenly the tv registered "no signal" yet the macbook was still saying it was connected to the tv. I thought it may have been a problem with the tv so I tried on another tv in the house, same result. So then i thought it may be the hdmi so i switched them, same result. So now the only problem could be the adapter or my laptop, does anyone know how I can fix my problem???

Greetings obomb2000,
Thank you for visiting Apple Support Communities.
It sounds like your MacBook Air is not outputting video to your TVs using an HDMI adapter, and you've done a good job of isolating this behavior to either the adapter or laptop.
Here are a few additional steps you can try on your MacBook Air before trying another adapter:
Reset the system
You can reset the Mac's parameter RAM and SMC.

Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
All the best,
Jeremy

Drobo not working after 10.5.8 update

My drobo stopped working after 10.5.8 update. Now I lost all my data on the drobo. this doesn't make me happy.

'We are using the USB interface (as opposed to firewire) because we want to share the drive across the network - it's not always about speed.'
This makes absolutely no sense to me.. but maybe I am wrong : Because firewire is much more reliable than USB and manages to keep highest transfer rates (without jumping up and down as USB would do as soon as I/Os go up...) Especially on a Mac ! (only for the latency I am not too sure, but I guess it is similar on fw and USB.. just increase the caching if you stream hd movies on the network...
From my experience, sharing a USB drive on the network is probably much worse.. you can find example on the web.. (Orb, Plex and else will start drop frames when connecting to a USB shared drive.)
I currently use my drobo plugged to my Mini with a fw800 to 400 cable,4*1.5tb hdds, I also share it on the network with gigabit ethernet, and get much better performances than any usb shared drive.
Sorry I do not have any precize measurement, but I can upload or download a 6tb file in about 10minutes over gigabit ethernet, and I guess the bottleneck is now the Drobo controller...
The protocol you use may have an impact as well (afp, smb,...) but whatever you use, I suppose Firewire will be faster.
As a general advice, do not update or upgrade anything in general before you have a backup of your data, this is true for any storage system, Drobo or not.
Oh, and Data redundancy on a raid is not a backup of course.
