Thanks for the question. The license agreement is for one license per computer running at a time. Users who want to run separate copies on different Macs simultaneously are expected to purchase additional licenses for those Macs.
Can you point me towards how to get the licensed version up and running on another mac? I think I saw a thread of this last night but now can't recall where it was located. I don't know if a license key is required, but I'm pretty sure I won't be able to find that easily.
