Question: Will this work on a Mac OSX 10.9 computer? I just upgraded to Mavericks and need an ethernet adapter.
Document: They include a CD with the driver, but of course if you don't already have a USB CD drive or another computer to read it, then you have to go download it. You're better off doing that anyway as the one on the CD doesn't work right with Mavericks. Get the download at [...]  (scroll down until you see Apple Mac OS X 10.9 Driver). Performance is right on par with built-in gigabit ethernet.
This doesn't work with OSX 10.9 Mavericks. It doesn't just work out of the box. I had to buy an Apple Adapter afterwards.
The Cable Matters USB 3.0 to Ethernet adapter works as described with no issues. I primarily purchased the adapter for use with my Macbook Air (2013, 13 inch) to connect to Gigabit ethernet. Speed tests consistantly reach up to the maximum speed of the network-- up to 700-800 Mbps. When paired with an external USB 3.0 hub, the adapter also works perfectly.Note-- on Mac OS X Mavericks (10.9), the listed driver will not function properly. You must use the driver provided by Pluggable, who manufactures a competing adapter with the same chipset used by Cable Matters: [...]After reinstalling the driver, the adapter works perfectly.
I was using this adapter successfully with a Macbook Air 10.8 Mountain Lion. When I upgraded my OS to 10.9 Mavericks, my laptop could not connect to the internet with this adaptor. So I had to go to this link: [...]Download the "Apple MAC OS X 10.9 Driver". It requires you to restart once the download is complete and the result is a successful connection to the internet!
Since Thunderbolt hubs are still so expensive, I am converging on USB3 instead.This ethernet adapter got 60 MB/s to my previous MacBook through a gigabit switch, which is comparable to 47MB/s tested through the Apple Thunderbolt ethernet adapter (no real difference given it was just a quick test).You will need to download &#34;ASIX AX88179/178A Macintosh OS X 10.9 driver&#34; from the Internet for it to work.This, plus a USB3-&#62;eSATA converter for my external drive enclosure (since the new MacBooks have no FW800) is giving me a nice migration path without a huge outlay for new Thunderbolt peripherals.
I'm using the OEM driver named AX88179_178A_Macintosh_10.6_to_10.8_Driver_v1.6.0_Binary_20130911.zip from ASIX and it seems to work fine with Mavericks 10.9. I haven't tried really hammering this thing and maybe over time it will fail for some reason, but for now my $20 seems to be well spent. I'll update this review if it seems warranted.
Edit: they have updated the drivers and it works again.Original Post: There are no drivers available for my Macbook Air running OS X 10.9 Mavericks. The adapter is useless to me until they update the drivers. I wish I could return the item, but it has been too long since I ordered.
I bought this nifty adapter in place of the more expensive thunderbolt USB adapter both to save $$ and to leave the one thunderbolt port available for other usage. The unit performs well - I can hardly notice the speed difference using the adapter versus not using it. The only caveat is that you need to go to www.cablematters.com and download the latest driver for your computer. I am using a MacBook Air with OS 10.8, and the driver CD that came with the adapter is an older version that doesn't work with OS 10.8.
Cable Matters USB 2.0 to 10/100 Fast Ethernet Adapter in Black is an excellent product, especially if you&#8217;re troubleshooting a computer and you need to have internet access to upload drivers and files as can be read from my blog article below[...]I especially like the fact that it has a long flexible neck, instead of being a USB stick. That way, it doesn&#8217;t crowd the USB port, leaving it free for me to plug other devices into that port.
Worked perfect for my OSX 10.9 2012 iMac with no drivers required at all. Tried in WinXP and also worked too
Answer: After installation of new driver and restart, the USB3.0 to gigabit connector works great on Mavericks as of 2014-06-05. Have 1Gb/s connectivity and up to 60MB/s throughput for file transfers on our lan.
