Hi Jorgr,
first you should try to find an answer to your question on the forum before you create a new one. It think that this http://forums.ni.com/t5/LabVIEW/Building-executables-for-a-Mac-on-a-PC-version-of-LabVIEW/td-p/509633 is answer to your question.
Here you can find information about LabView and MacOS http://www.ni.com/mac/
