How to deactivate or transfer your license ?
It is very easy. Three clicks.On the computer you want to deactivate : open the Preferences (shortcut CMD+,), and select the tab called "Activation" (see image below).
Then click on the "Deactivate online" button (Millumin will display that it is in "trial mode")
Then, on the computer you want to activate : open the Preferences, and select the tab called "Activation" (see image below).
Then click on the "Activate online" button, and enter your product key. You will be asked for your administrator password.
That is all : Millumin will display that this new computer is activated.
You can know more about your activated machine on your account page.
If you reinstall OSX, no problem, you can reactivate Millumin : the license server will recognize your machine.
If you plan to change hardware on your machine (or sell it), you must deactivate Millumin first (and any licensed software installed on this machine).
If you have an error, be sure the clock of your computer is correctly setup.
