Difficulty making a Mac app that works on another laptop

[Georges Malamoud]

It is a standard issue on Mac. Apple protects their systems for non officially code signed apps.
There are some procedures to circumvent this with your app
- if you are an Apple official developer (like me) you have to include a developer certificate in you app
