Finally

A very good first try to go OSX. Some issues in this version
German ICAO is not in the same scale in the west part when Belgium and Netherland Open source maps are activated. The ICAO Map then gets crippled.
Unfortunately Aircrafts and the logbook from the Ipad versions cannot be synchronized. The Logbbok is not supported at all.
The GUI is much different the the IOS version and so to find the same functions than with the IOS version is a bit irritating.
Official NOTAM Sources are not supported also weather from DWD is not supported.

Therefore the software cannot be used for a full flight planning under German VFR rules.
