Hi, I need an ethernet adapter for our work retina MBP so I can access my development environment. I see that his one from Monoprice is recommended but can anyone recommend one available in the UK? I don't particularly want to shell out for the Apple one. Looking on eBay, this one looks very similar: http://www.ebay.co.uk/itm/Ethernet-10-100-Network-Adapter-USB-to-LAN-RJ45-Card-/370537388243?pt=UK_Computing_Other_Computing_Networking&hash=item5645bfd8d3 Does anyone have any experience with something like this with Mountain Lion? I'm concerned about drivers and OS compatibility. Thanks.
