Your licence, your Macs and updates

1. Open Settings, then License.
2. Paste the key from your purchase email.
3. Activate.

1. On the old Mac, open Settings, then License.
2. Choose Deactivate & Quit. That releases the slot immediately.
3. Activate on the new Mac with the same key.

The licence is re-checked quietly in the background after three days. If a check cannot get through, Tucket keeps working for a further fourteen days before it asks you about it. An outage or a week without wifi is a non-event.

They install themselves in the background, with the changelog shown in the update dialog so you can see what changed before it lands.

Updates are incremental, so only the difference is downloaded. A 1.3.0 to 1.3.1 update was about 318KB rather than the full 5MB.
