I have been going through amazon reviews, all over mac rumors, and having a problem finding a good powered USB3 hub. I have my 2012 mac mini in a hi-rise stand with my monitor, I was looking for a USB3 hub for extra ports and so I don't have to keep reaching in back. But most of the amazon reviews complain about hubs that die or don't work with external HD's plugged into macs. On mac rumors I keep reading about OSX having a bug that screws up any hub with more than 4 ports. I need whatever I get to run external HD's and mouse or keyboard if my wireless ones die. Any suggestions?
