That's not a panic log. If you have more than one user account, you must be logged in as an administrator to carry out these instructions.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Select the most recent panic report (with a name that begins with "Kernel" and ends in ".panic") under the heading System Diagnostic Reports on the left. If you don't see that heading, select
View ▹ Show Log List
from the menu bar. Post the entire contents of the report — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post any other kind of diagnostic report, such as a hang report.

USB Ethernet will not configure

Hello,
Today I started to have problems with my USB Ethernet dongle on my Yosemite Macbook Pro Late 2013 Retina. I deleted the device from Network Utility then rebooted thinking I would re-initialze it. After rebooting, the System Info recognizes the USB LAN device but Network Utility does not list it. This appears to be software issue. I have confirmed the dongle works fine on another laptop (Windows). Any ideas how to fix this issue?
TIA

The driver is built into Mac OS X. The dongle worked fine for weeks on Yosemite. It is a Cable Matters Cable Matters USB 2.0 to 10/100 Fast Ethernet

Usb ethernet problems

I've gone through several USB Ethernet dongles today. One was a generic product that worked for less than a minute and forced me to shut down my macbook air, the second was a Belkin that never worked and the 3rd was an actual new Apple USB/Ethernet dongle. The last two never worked at all. Is there some special procedure to get these adapters to work?

You can try to download the latest ASIX AX88772B/AX88772A/AX88760/AX88772 Mac OSX 10.7 driver v3.5.0 from ASIX's driver download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=97) and refer to the driver installation guide to update the revised driver onto your Lion Mac OSX 10.7 system.
For the AX88178 USB 2.o to Gigabit dongle, please refer to AX88178 Driver Download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=84) to download the latest AX88178 Mac OSX 10.7 driver v3.6.0 and also refer to the driver installation guide to update the revised driver onto your Lion Mac OSX 10.7 system.

Mail problems on Yosemite

Hi there,
Does anybody know if anything is going to be done regarding the mail problem on Yosemite?
this was a recurring on Maverics too...
Since i updated to Yosemite, mail does not work well on my iMac, i cannot get my mail... but i can send mail.
it does not seem to connect properly to my Pop account.
my mail does work well on my iPhone and other devices.
it was fine after the recent Yosemite update, and now it's back... and very frustrating,
is there anyone who can help ? or anyone at Apple that is going to fix it for once and for all ?
Thanks.

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

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

the link provide above leads to http://plugable.com/2014/10/31/os-x-10-10-yosemite-ethernet-adapter-problems-we- can-help
...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.

USB ethernet does not work in left USB port

My USB ethernet adapter does not work in the left USB port on my MacBook Air, but it works in the right side. Other devices, like my mouse, work fine in both ports.
Could I have a faulty left-side port with too little power for the ethernet adapter, or is this normal for MacBook Air?

I have the same problem.
USB Ethernet doesn't work with the left USB port. It does work with the right USB port, and any other USB device works with the left USB port on my macbook air
Any solution to this problem?

USB Ethernet no longer recognized?

Hi
After a reinstall of Leopard to remove languages and the sorts I had a slim installation on my air and everything was running nicely. Now however the USB Ethernet is not being recognized at all .. I have checked with the superdrive and no problems there. I have plugged the USB Ethernet dongle into my MBP and the dongle is clearly alive.
Why will my MBA not recognize the thing anymore? It just sits there utterly unresponsively, claiming that the cable is unplugged .. which it is not??
/Jan

Hmm .. one extra restart seemed to take care of business. How odd. Anyways everything is working here for me again

USB ethernet connection via switch no longer works after installing Mountain Lion

Since installing Mountain Lion, I have no longer been able to use my USB ethernet connection via an ethernet switch. I have deleted and re-added the connection in preferences. The connection reads "Connected" but it is not working as connected (unless I bypass the switch and plug directly). I have tried doing this with two different switches to no avail. Does anyone have a solution? Thanks.

I Read this sollution elsewhere on these forums and found that this worked for me.
However, the "load" time in Safari is not as fast as it used to be. Might be due to some router setting.
Solution:
For all the Dutch users that have a KPN Experiabox router:
1) go to http://192.168.2.254
2) Username: KPN Password: leave empty (You might have changed this yourself)
3) Go to Network (at the top)
4) Go to WLAN (at the left)
5) Set as follows:
Enable WLAN: Enable
Mode: IEEE 802.11g Only
Channel: 7
Transmitting power: 100%
Enable WMM QoS: Disable
This fixed my wifi problems. Good luck

Printing to the network via USB Ethernet

I have a pair of MacBook Air's that are using the USB Ethernet adapter to connect to the local ethernet (wireless is not an option, all workstations must be wired while in-house.)
The problem I run into is that both of these MBA's will loose their connectivity to the printers, or their ability to see bonjour devices at all, or Appletalk devices. In particular, I've installed a set of OkiData printers on the network which support both Bonjour & Appletalk. When I setup the printers as IP printers, they seem to work fine. However, if they, or any other printer, is connected as a Bonjour device, eventually the MBA stops recognizing/seeing/looking up Bonjour items on the network.
Any thoughts on why this is or how to correct it would be really useful, especially since some day the users might like to do some bonjour-based file sharing.
Thanks!

I have a client with the exact same problem. No bonjour when attached via USB ethernet (Apple's own) SOMETIMES. However, I've noticed that if she unplugs and tries the other usb slot, it seems to work (immediately, no reboot). I've actually only told her to do this over the phone, but it has worked at least twice.
One problem here is that the printers are NOT accessible via bonjour over WLAN, since the WLAN is at least 2 different C class networks.
The other is that due to the setup of the printers and crap drivers from Ricoh, using personalized printer queues only works over Bonjour and not TCP. Thus, only USB ethernet can be used for printing. It would be very interesting to hear if changing usb ports might help in your case as well. This particular client has a late 2010 MBA 4G/128G, but at the same department there are at least 7 MBAs where no-one has had the same problem. Either that, or they had it but never told me.

Cannot apply OS image to lenovo with usb Ethernet

Greetings,
We have a Windows 8.1 task sequence which works fine on over a dozen laptops that have an ethernet adapter. We recently acquired a Lenovo Helix machine that doesnt have an inbuilt adapter but has a usb ethernet adapter. I found the driver for this
and added it to our winpe image (we are using sccm 2012 r2, adk 8.1, winpe 5). When I use the same task sequence, it always fails on the apply OS image step. Relevant log entries here:

Does OSD have a problem with USB ethernet adapters? It appears so....
Thanks
David Z

Yes, it does have something to do with USB Ethernet. Before conclusion, we may check if there is a workaround or fix for this issue to make OSD work. So, please check the IP Info when the issue happens.
Another way is to use a Standalone media.

USB Ethernet Adapter Stopped Working On Mac Mini Server Running 10.6.6

Is anybody out there successfully using the Apple USB Ethernet adapter on a Mac Mini Server running 10.6.6? They have stopped working for me.
The boot disk in the 2009 Mac Mini Server in my classroom failed and after Apple replaced the disk and I reinstalled SLS and ran Software Update to bring the machine up to 10.6.6 the USB Ethernet adapter that was the interface to the outside world no longer recognized when a cable was plugged in. The cable was good and worked just fine if plugged into another machine or the built-in interface. At first I thought that the USB Interface had failed but after trying two new ones (graciously exchanged by Apple) and finding that none of them worked I'm coming to the conclusion that perhaps the warning on the package that the USB Ethernet only works with the MacBook Air finally became true.

Only the specific build of Mac OS X that comes with a MacBook Air includes the kernel extension to run the Apple USB Ethernet adapter, however there are no hardware issues preventing it being used on other Mac models if you have a suitable driver.
Generic USB drivers can be downloaded for free from http://www.sustworks.com/site/newsusbethernet.html and this worked for me.

Apple USB Ethernet (A1277) not working with Mavericks on MBAir 2012

USB Ethernet works on other computers (Mac Pro) and did work with this 2012 MBAir with OS X 10.8.
Any ideas? Other brand USB ethernet adapters (Cisco and generic Ebay USB 2.0 Gigabit adapter) work fine with this MBAir and Mavericks.

That's an overly broad statement. I have a TB equipped Mac Mini and the USB Ethernet adapter works fine with it. It's only Fast Ethernet (100MB) while the TB adapter is Gigabit Ethernet (1000MB) but it does work. Also worked fine on my TB eqiuped MB Pro.

Thunderbolt to Gigabit Ethernet Adapter problem

Hi all
I have replaced my black 2008 mabcook with the new 13" retina MBP.
I bought the Thunderbolt Gigabit Ethernet Adapter to connect to my office network.
A access without any problem to Intranet content and file server, but when I use Internet, where I must connect via a proxy, I constantly get error messages like "the server unexpectably stopped the connection" or a Proxy error "The number of HTTP requests per minute exceeds the limit".
I got my black macbook back to my office to test and I have no problems with it.
At home, I also have no issue using the thunderbolt adapter.
Any suggestions?

It is always best to speak to the IT and see what they think.
I was just guessing in my post - they should give you the full answer even if they cannot alter the settings for you.
From your side you can try to work out what is generating big amount of http requests (applications you run on your MBPr while in the office?).
Also USB to Eth dongle may slow you down :-)

but I understand that buying something worse than you already have is not really an acceptable solution.

USB Ethernet no longer shows in System - USB or on network list

Hey,
I've been using a USB Ethernet to connect my Macbook Air to the internet for around a month. A couple of days ago it stopped working, showing 'Not Connected' in the network list. I followed the standard advice of swapping out locations, didn't work becuase I couldn't add the USB Ethernet to the list. I then took the advice of removing the Automatic location, and now the only network that is listed is wifi... Nothing gets added to the list, when I try to tether over USB with my phone it doesn't get added correctly to the network list either.
I've reset my SMC and PRAM too.
In System -> USB it doesn't seem to be listed either, although it does detect something, it doesn't seem to be able to realize it is my USB ethernet.
ifconfig -a shows the following;

Would really, really appreciate some help on this, as I am pretty new to Mac OSX.

Apple USB Ethernet Adapter after reboot

Hello everyone,
We have a group of 3 or 4 MBAs that are showing this same issue. Whenever we reboot we need to unplug and then replug in the ethernet adapter in order for it to connect to the network. This same problem is seen regardless of the adapter being plugged directly into the computer or through a USB hub.
It also happens when we "undock" and then dock back in from the USB hub.
Has anyone else see this issue? Have you found a solution?

Yes, Yes and NO!
What's worse is sometimes you get full 100Meg/Full Duplex and even Bonjour services, then for no reason it connects at 10base half duplex and NO BONJOUR.
I'm convinced it's the USB-Ethernet adaptor, as I get the same problem using it with a MacBook Pro, at first it works great, then you restart and it looses Bonjour and sometimes you can see all the Bonjour enabled devices drop off the Shared list in the Finder.
I've had this problem ever since I started using the MB AIr (Late 2010) model.
I don't think Apple are bothered about fixing the problem, as they seem to assume all MB Air users are on Wireless (which also has it's problems)
It remains to be seen if Lion fixes it or they just give up and go to ThunderBolt on the next generation MB Airs with a suitable Gigabit adaptor.
