How do I add a location to my pictures in Photos?
I've just upgraded from iPhoto to photos v1 on my macbook Air but I no longer seem to be able to add a location to each picture in the same way I could in iPhoto.v9.6.1 Fortunately, I still have the old iPhoto on my iMac and it may well stay that way.
MacBook Air (13-inch Mid 2013), OS X Yosemite (10.10.3)
