Routeconverter 64 Bit version for Mac seems to be damaged

[mvdz]

The error is a bit ambiguous but the problem seems to be in the security and privacy settings of OSX. Open this, and set the security to "Any source" then open Routeconverter and then set the security back to the previous level. This solves the problem.

So you've solved the problem by following the GateKeeper advice on the download page?

Well actually I did not read the advice (shame on me) :-) but I followed my gut feeling ...
