Activate and deactivate a license
Paste your key in Settings → License, and free a Mac's seat when you switch computers.
A license key activates EaseKit on up to three Macs. Activation registers this Mac with the license server; deactivation frees its seat for another Mac.
Activate
- Find your key in the email from Polar (or in the Polar customer portal).
- In EaseKit, open Settings → License (or click the license badge in the toolbar, when it shows).
- Paste the key (the Paste button helps) and click Activate.
This Mac is registered with a label like “Mac name · model”, which you'll see in the customer portal. EaseKit keeps the key in your Keychain and shows only its last four characters.
Staying valid
EaseKit checks the license at launch, at most once a day. If you're offline, the last good check holds for 14 days (shown as “offline until …”). Click Check Now to check right away.
Deactivate this Mac
- Open Settings → License on the Mac you want to free.
- Click Deactivate This Mac… and confirm with Deactivate.
- The seat is free for another Mac. You can activate this one again later with the same key.
Troubleshooting
| If this happens | Try this |
|---|---|
| “This key is already active on the maximum number of Macs” | Deactivate it on another Mac first, or free a seat in the customer portal. |
| “This license key isn't valid” | Check for typos (paste it with Paste). It may also have been revoked or expired. |
| “Couldn't reach the license server” | Check your connection and try again. An activated Mac keeps working offline for 14 days. |
