You can install your version on all your computers without restriction.
Absolutely nothing is modified on your system by Usine.

To install Usine on MacOSX, just unZip the package anywhere on your computer and drag & drop the application (.app) in your application folder.
Avoid third-party software, use the default Mac unzip utility and dbl-click on the extracted file .app (application package).
Some MAC users report this type of messages "Usine.app can't be opened because it is from an unidentified developer" don't worry this came from Gatekeeper, not Usine. Gatekeeper is a new feature since OS X Mountain Lion, see this page for more details
