Love the flush design, wished it locked better
on July 15, 2017
I wish there was a Mac out-of-the-box compatible USB 3 card that is flush with the machine (instead of hanging out the side). I'd pay $100 for something like that. This chard is cheap, flush, offers decent speeds, but doesn't lock into the slot well at all.
It pulls right out of the slot when unplugging a USB cable. I used a layer of foam adhesive to make the connection tighter in my Late 2011 17" MacBook Pro, but I still have to hold the card in while I pull the cable out.
This does work with Mac OS with a few caveats. First, you need 10.7 or 10.8+ (can't remember which it is at this point), and you need to install the GenericUSBXHCI.kext (goodgle it). If you're running 10.10 or 10.11 (again, can't remember which it is), you need something plugged in to the port on reboot for the card to initialize.
