How to fill PDF forms using Mac OSX Preview

You may often receive interactive forms in PDF format from HR or staff assistants. If you fill information using Mac OSX Preview and sign it ( which is the advantage to use Mac Preview ) and send it back, person who made the form may not see any information in Acrobat Pro. So the recommendation is to use 'export to PDF' function from Preview menu to create a new PDF without Acrobat specific information.
