My Mac can't detect my iPhone hotspot
I've got a hotspot on my iPhone (iPhone 5, 8.1.3), it works great with my iPad2, but not with my Mac Book Pro (10.10.2). I expect the hotspot to appear in the list of available wi-fi's so I can select it, but it doesn't. Haven't been able to find any advice online that has been helpful. Sound like a trivial matter and that I've just got an incorrect setting somewhere, but can't figure out what it would be.
Mac Pro, OS X Yosemite (10.10.2)
