Answer # How many Macs can I use Clacky on? One Clacky licence works on 1 Mac at a time, and you can move it to another Mac whenever you like, for free. To use Clacky on two Macs at the same time, buy a second licence. Keys bought earlier keep the Macs they came with, which is 2 Macs for keys bought before 28 October 2026.

That uses the key’s place for one Mac. The model name is there so you can tell your Macs apart in Polar’s customer portal. Clacky never sends your name, your computer’s name or a serial number. Settings → Licence shows “Clacky is activated” and which Mac it is on. ## Use your licence on a different Mac Moving takes about a minute. The full guide is [how to move your Clacky licence](https://clacky.app/answers/move-licence-new-mac/). 1. On the old Mac, open Settings → **Licence** and click **Deactivate…** next to Move to another Mac, then **Deactivate**. 2.

Use Move to Another Mac on that Mac, or free it in your Polar customer portal, then try again.” The [Polar customer portal](https://polar.sh/clacky/portal) shows your Macs and lets you free one. Sign in with the email you bought with. ## Families and teams Each Mac that uses Clacky at the same time needs its own licence, so a family with two Macs buys two.
