Tom,
Thanks for checking in. At this time, no further development has been made on a iFly Connect solution for Mac just yet. It is still on our development list, there are higher priority items we have to focus on at this time. Additionally, we will be looking at some update sharing from an iPad / Androiid that may also intergrate or resolve this Thanks for your inderstanding and patience.
Our focus at this time is getting the new V8 update out to the iFly 700 / 720 / 520 that will make it a more uniform experience with the iOS and Android Apps. There is also a Phone or Small Display mode in the works that should benefit the 520 users as well.
