It wouldn't be unlike Apple to strip device IDs they hadn't tested though, so chances are admittedly slim. I suspect the reason they haven't shipped a USB 3 NIC of their own is that they expect the thunderbolt port to be open or taken by an Apple display with its own built in NIC. The USB NIC was for pre-thunderbolt Macs. Click to expand.From the Amazon reviews section for this: 'When the latest version of Mac OS X (Mavericks) shipped, this stopped working.
The advice from tech support was to re-install the old OS. They also said it would be several months before a new driver would be available, even though the beta had been out for developers since June.'
This is the problem with ANYTHING that requires third party drivers. You basically are a slave to running a version of OS X that supports that driver, and lose use of your device when you upgrade until the driver is updated. Sometimes the driver is never updated and your device becomes a paperweight. I fully understand the OP's quest to find one that doesn't require a third party driver. Sadly I think OP is SOL on this one.
Click to expand.Nice find, thanks! Searching on the RTL8153 chipset, there are a few other USB NICs with and without USB hubs. Reviews mention driverless support on several of these, although some also complain about the NIC becoming unresponsive after sleep and resume. The cheapest of the no-hub variants is just $12 with Amazon Prime 2 day shipping. For that, I'll give it a shot myself instead of trying to troubleshoot others' sleep/wake experiences (did you use it on a USB 2 port or USB 3? Did you load other bus powered devices on the hub?

I'll report back after I've exercised it a bit. Nice find, thanks! Searching on the RTL8153 chipset, there are a few other USB NICs with and without USB hubs.

I'll report back after I've exercised it a bit. Click to expand. I used it on a USB 3 port and got full gigabit Ethernet speeds.
I think you'd max out around 200Mbps on USB 2. I've connected a USB 3 bus powered HD and an externally powered USB 3 HD.
Both worked fine. I hadn't notice the sleep/wake issues because I don't usually keep it plugged in all the time.
I read that there is an updated driver that solves the problem, and I'm assuming Apple will eventually roll that into an OS update in the future. Probably won't affect my use case either way, though. Glad you found one with Ethernet only. I was looking for more USB 3 ports, as well, so this one was perfect for me. I also didn't want to use up a thunderbolt port, as I need that for my non-Apple external LCD display. Sorry to resurrect an old thread but curious if any of the previous posters actually got this adapter working without drivers and if so, how? I ordered the same USB3.0 gigabit adapter pictured above and it definitely is not working out of the box with my 2013 rMBP running 10.10.5.
