Upgrading from WL6 to WL7

Hi there, I have WL6 on pc and want to upgrade to 7 via online delivery. I presume I keep the same dongle for this?
I also want to install WL7 onto a MacBook pro, can I do this with the upgrade or do I need to buy full version again?
Cheers

Same dongle.
You can install on several computers. But you have to move the dongle on the computer you work on. If you want to work on two computers at the same time, you need 2 licenses.

The question might have been whether the single earlier PC purchase entitles the user to install on the Mac - my understanding is that it does.

Right, Windows or Mac, this changes nothing to my comment.
