Worked great upon installation...... turned computer off.....restarted.....and would not work. Reset entire system...and would not work. Removed and reload and the unit worked. If I leave my computer on and do not restart all is fine.
Product works, but doesn't come with Mac drivers. Ultimately, I figured out that Mediatek 7610U drivers do the trick, and since then, no problems. Also, no box or instructions came with the device, so I had to figure things out on my own.
