the cdk installer for MacOS installs DevStudio and the CDK into <Home>/DevelopmentSuite.
There are a few non-optimals here:

• Home is afaik not visible by default in Finder.
• Furthermore applications are by default installed into Applications in MacOS.

Possible improvements:
In order to behave like a first class MacOS-citizen we should install DevSuite and CDK independently into Applications (or maybe CDK into Document as it isnt the application in the strict sense, it's only a Virtualbox image, a Vagrantfile etc.)
