Unofficial drivers for the card are available here in kext form. You’ll need a kext ( kernel extension) installer - I used Kext Wizard. You’re probably working with a real Mac, but to get the card working you’ll need to use some hackintosh tricks. It will not work out of the box, and neither the provided driver CD nor GMYLE’s website has Mac drivers. I could not find any USB 3.0 cards that officially provide Mac support, and the GMYLE card I linked is no exception. I bought the GMYLE ExpressCard 34mm to USB 3.0 Adapter because it is relatively cheap, has a compatible chipset, provides two ports, and does not protrude out of the MacBook.
You’ll need an ExpressCard 34 USB 3.0 card. Fortunately, this Mac is old enough that it still has an ExpressCard port. However, my external hard drive and DisplayLink monitor support USB 3.0, so file transfer and screen refresh rates are not nearly as good as on the Windows laptop. Although I bought a Windows laptop a year ago, I still use my MacBook Pro from 2007 which is still usable thanks to RAM and hard drive upgrades.
