where are the movies i just rented on my mac?

Take a look towards the bottom of this page where there are several articles on how to deal with movie rentals:

I agree Don't send me onto Apple's Help pages where they don't answer the question. Where are the rented movies in iTunes?!

These forums are user to user only; there are no Apple employees here.

Without specific information (Mac model/year, OS version, iTunes version, etc), there is no way for any specific help. We cannot see your machine or setup.

You can contact Apple - see the link at the bottom of the support page:

Are you talking on a different machine or the movies you rented on the same mac? If its on a different machine, you need to set up icloud. same machine? im not sure...
