More and more pilots are using Mac, so am i. One reason I opted for Skydemon for my VFR flight planning  (IFR I use Rocket Route) was the offered mac version. Unfortunately I noticed only later it was not supported. My fault.

However, I would like to report the following bug: When storing an aircraft I get error message. 
"Unhandled exception has occurred... value either too large or to small for a decimal". If I click on the details bottom left I see the text listed below.
Practically the program kicks me out then, and I see the terminal window in the dock. Without my aircraft set up flight planning makes no sense really 
My system: Imac 21" 2013, latest OS (maverick 10.9.5 ) , 16GB Ram 
Thanks for an advice
best
Frank
