Licensing FAQ

Licensing is managed by Paddle.

How do I change the email address associated with the license key?

Section titled “How do I change the email address associated with the license key?”

With Paddle purchasing/licensing, you are prompted for:1. An email address for the purchase transaction. 2. An email address for license activation (if you don’t activate it immediately).

The transaction email address cannot be changed. If you entered the wrong email address during purchase, I can forward you the Paddle emails with the license key to the correct email address.

The only use for these email addresses is to look up the transaction or the activation/key (in case you lost it).

To change the email address for a license key activation:

Section titled “To change the email address for a license key activation:”
  1. Deactivate your license from the General tab of the Settings window.
  2. Reactivate your license by entering the desired email address and the license key.

How many devices can I use with one license key?

Section titled “How many devices can I use with one license key?”

You can have 3 active devices with one license key.

If you have utilized all of your license activations and are trying to activate on a new Mac that is not activated, there is a button to remove the oldest activation in the General tab of the Settings window.

You can also remove your license ahead of time if you know you are going to lose access to a macOS install, with a button in the General tab of the Settings window.

Where can I look up my license key if I’ve lost it?

Section titled “Where can I look up my license key if I’ve lost it?”

If you know the email address you’ve used to purchase it, you can go to https://my.paddle.com and log in there to obtain it.

How do I move a license to another device?

Section titled “How do I move a license to another device?”

One license can be active on three devices. If you are getting ready to part with a device or reinstall macOS, you can preemptively remove an activation using a button at the bottom of the General tab of the Settings window.
