2. Looking for an USBEthernet adapter supported by the Surface RT. But so far, only one USB-to-Ethernet driver works with the Surface RT. And, that driver only works with USB-to-Ethernet adapters using the AX88x72A chipset. A website named Plugable lets you download the free driver and buy their adapter.

J5create's USB 2.0 Ethernet Adapter JUE120/JUE125 is a quick and easy way to add an Ethernet port to any Mac/Windows/Linux computer via a simple USB port.

I am plugging a USB Ethernet adapter (not Apple-brand) into my MacBook Pro (Retina, 15-inch, Late 2013). No go.

I do not see any relevant 'USB Ethernet' item listed in System Preferences >Network. Should one appear when I plug in the adapter? Should I add an item with the '+' button?

When I use the '+' button, I only get a list of 'Thunderbolt Bridge', 'Thunderbolt 2', 'Thunderbolt 1', 'Bluetooth PAN', 'Wi-Fi', 'VPN', 'PPPoE', and '6 to 4'. I do not see any option for a USB-Ethernet adapter. Is this no longer supported by Apple?

The Apple menu > About this Mac > System Report (button) > Hardware > USB report shows that I have a product by Realtek Semiconductor Corp. (company web site)

As far as I understand, you can run a lot of generic ones that don't have Apple-signed drivers by disabling 'System Integrity Protection' (SIP)

From: http://inkandfeet.com/how-to-use-a-generic-usb-20-10100m-ethernet-adaptor-rd9700-on-mac-os-1011-el-capitan

Steps to get your adapter working if you've never used the adapter before in Mac OS 10.11 El Capitan.

1. Uninstall the dozens of other drivers you may have installed in the process of trying to get this working.
2. Unplug your USB adapter, and reboot and give yourself a clean slate.
3. Reboot. As soon as the screen goes black, hold down 'Command' and 'R' until you see a black screen with an Apple logo and a white progress bar. Let go, and wait for your computer to boot into recovery mode.
4. From the top bar, select 'Utilities' and then 'Terminal'
5. In the terminal, run csrutil disable.
6. From the top bar, select '', then 'Restart'
7. Once you're booted back up, download and install the drivers from the CD, kindly uploaded by this fine human being.
8. Reboot.
9. Open your terminal, and run sudo kextload /System/Library/Extensions/USBCDCEthernet.kext
10. Reboot.
11. Plug in your USB Adapter, with a live ethernet cable.
12. Open System Preferences, and go to the Network Pane.
13. Hit the + button in the bottom right, select the 'USB 2.0 10/100M Ethernet Adapter', and hit add.
14. You're all set! Your adapter works!
15. Apologize to the people you care about for the things you've said over the past few hours. They won't understand, but they will forgive you.

I presume that any driver that worked for these types of things pre-Yosemite (10.10) would work for the ones in step 7.

See original page for a discussion on the security risks of using this method. But, if you need it to, and are aware of and OK with the risks, it works.

This worked for me on El Capitan (10.11) with a random off-brand adapter (can't remember the brand or if it even had one).

For Realtek based USB 2.0 or 3.0 Ethernet Adapters, you can get the driver from Realtek which works for both 8153 and 8152.

Old post, but just wanted to give an update.

Sometimes you just need to install the chipset's drivers.

If you are lucky, you will have an Asix's chipset and you can follow these steps to get it working. I did with an Acer's USB Adapter and it worked perfectly.

For a Cable Matters adapter, I had to get the drivers from here:http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=131 /123movies-app-download-for-mac.html.

If your adapter wasn't specifically advertised as Mac-compatible, then its unlikely to work. There are a couple of 3rd party brands that positively will work but I wouldn't trust just any off brand adapter and if its a PC manufacturer brand, then it definitely won't have the internal circuitry that a Mac-compatible adapter will have so the answer, unfortunately is just.. no.

See: [Do I have to use the Apple USB Ethernet Adapter for a MacBook Air? for further details on adapters that definitely are compatible.

A proper instruction for RD9700 is here https://www.technouz.com/3973/how-to-use-a-generic-usb-ethernet-adapter-rd9700-on-mac-os-x/

This is the only manual I've found so far that has ALL necessary steps.In particular step 7 is critical (install drivers from x86_64 folder).

I managed to get my noname adapter working, but the internet speed is only 5mbps although I have 100mbps connection :(

Step 1: Unplug your USB adapter.

Step 2: Restart your Mac by clicking the Apple logo in the top-left corner and then Restart. As soon as your machine restarts, you’ll hear the Apple chime. Hold down CMD + R immediately after hearing the chime to boot in to Recovery Mode.

You can release CMD + R once you see the Apple logo and a progress bar.

Step 3: From the top bar, select Utilities and then Terminal.

Step 4: In the terminal window, you need to type the follow and then hit enter: csrutil disable. You may be prompted for your Administrator password.

Step 5: Now from the top bar, click the Apple Logo and then Restart.

Step 6: Your Mac should now restart back in to the normal operating mode. It’s time to install the drivers. Click here to download the zip file and extract it to your Desktop.

Step 7: Install the RD9700 driver located in the x86_64 folder and then restart your Mac again.

Step 8: Once your Mac has rebooted, open Terminal and enter the following then press the Enter key: sudo kextload /System/Library/Extensions/USBCDEthernet.kext.

Step 9: Reboot again.

Step 10: Now plug-in your USB Ethernet Adapter with a live ethernet cable. Open System Preferences and go to Network.

Step 11: Press the + button in the bottom right and select USB 2.0 10/100M Ethernet Adapter and then click Add.

Step 12: Disconnect from WiFi and you should notice your network connect still works through the RD9700 Ethernet Adapter. In addition, you will be able to share internet using the RD9700 too.

You don't describe which adapter you might have bought, but if the OS does not provide a driver for it, you will have to install a driver from the manufacturer.

J5create Driver For Windows 10

I have a Macbook Air running 10.7.4 and I'm trying to connect to ethernet using the official Apple USB to ethernet adapter. However, the mac never detects the new network interface. It never displays a dialog asking me to set it up. It doesn't show up in network preferences. As far as I can tell, the mac doesn't know it's even plugged in.

I've verified both the adapter and the ethernet cable I'm using work with another mac. I've tried both USB ports on the Air.

Anyone have an idea how I can troubleshoot this? Is there a USB utility that I could check out?

I had the same problem and a couple of minutes ago I saw something about the 'Android File Transfer Agent' having problems with the device.So uninstalled 'iSyncr' software (sync android over Wifi), disconnected the usb device, plugged it again and now it's working fine.

Yes - you should see the hardware device in Lion's System Information pane under USB devices if it has any working pins that the computer can see and sense.

Sam broadcaster free download for mac. From there, it's an OS / driver / kernel issue and the simplest thing to do is often to install a clean OS on an external drive and see if it's somehow a setting or corrupt preference file.

These have been out for so long, it's very unlikely the OS doesn't have the correct driver, so it's more a glitchy or buggy situation as opposed to the very new Thunderbolt to Gigabit Ethernet where most Macs that shipped before this last batch need a thunderbolt firmware update to make the OS see the adapter.

I have INSIGNIA USB to Ethernet not detected. I installed driver from here: http://www.nikvdp.com/technotes/getting-non-apple-ax88772-usb-ethernet-to-work-on-mavericks/and it works now.

I've resolved by simply create a new location in Network Preferences and then try connecting it again by clicking 'Apply' on this new location.

On my 2017 15' MacBook Pro a simple reboot solved the issue. Always try this first, before trying a crazy solution.
