license mode with two developers

Hello,

We have 2 developers:

1 developer with 1 computer - only works with unity pro

1 developer with 2 computers (macbook pro and imac) - works with unity and unity ios

And I have 1 license (unity pro and ios), the question is this: We need another license or I can upgrade my license in order to work with 2 developers?

Thanks and regards.

You need a second license, it's always per seat

And you can not mix Free with Pro.

(says the EULA.)
