HI,
You can install and activate (purchased) perpetual software two computers of the same type (mac or pc), as long as you only use it on one at a time.
It is a good practice to deactivate software on a computer where it will no longer be used, especially before giving away or selling the computer, or reformatting the hard disk. Please see this link: how to deactivate software. This frees up one activation so you have the option to install the software on another computer at any time.
