There's a solution out there somewhere. SteveRe: Rand McNally GPS compatibility issues MacBook ProFrom the looks of things, I'm a little late to this discussion. I'm having same problem with new iMac at home running 10.9.3. I have an older iMac at my office running same system (10.9.3), but works on that model. Has anyone heard anything new from either RM or Apple regarding problem? Thanks in advance for any response. Steve Fleetwood Discovery 2006 Jeep Grand Cherokee 2011
