If only there were somewhere a list of usb3 devices and hubs that are "known to work" with Mac.
It would be a complex list me thinks... A lot of devices which work in one version of OS X do not in other versions: 10.6.8 to 10.7.0 to 10.7.5 to 10.8.0 to 10.8.3. Which also makes me think Apple OS developers are kinda on the lame side. (actually I don't need to think it as it's pretty obvious given what they have and haven't done since 10.5.0 !!!)
