I don't use Apple's wireless mouse or keyboard; got a 2nd hand wired keyboard off ebay and bought an wired Amazon mouse (their own brand). Have used Macs ever since I started and Poser since version 4. The only problem I had was way back with Poser 8, which ran badly on my Mac. Quite happy with PP2014 on new iMac and Yosemite. (Can't recommend El Capitan yet).
