Yes, you can.
At any moment you can go to the "My Account > Profile" area on our website and release (unlock) your license from the latest computer it was used on. Once you do that, the online activation system will bind (lock) your license to the next computer you run Maverick on.
There is no limit to the number of times you can lock/unlock your license.
What you cannot do, however, is run one license simultaneously on multiple computers.
