I would like to have an app for OSX which can make Object-Role Models, similar as this one.

I use currently Top Coder's UML tool. However, it has some weaknesses: I cannot change the order of columns easily and it is time-consuming to label arrows.

What is the best ORM -tool for OSX?

The only tool I have found for doing any type of diagrams in OSX that really works is OmniGraffle. It is not free but well worth the price.

However this Wikipedia entry lists a few different options for various platforms and development languages.
