Licensing and changing your Mac

What your license includes

Each license key covers one macOS device. Website plans also include iOS access. A one-time license never expires and includes lifetime updates; a subscription provides access for its paid term.

The free trial lasts 48 hours and requires an email address and internet access to activate, with no credit card required. After the trial, you need a license or subscription to continue.

If activation or validation fails

1. Check your internet connection. Hyud needs internet access to validate a license or subscription.
2. Check that you are using the license and email associated with your purchase.
3. If you use a subscription, verify that you are still within the paid term. An expired trial is not a paid license.
4. If your license is linked to a previous Mac, follow the device-change steps below.

If these checks do not resolve the error, contact support with your purchase email, macOS and Hyud versions, and the exact error message. Do not include your full license key or payment details.

Move to a new Mac

A license covers one device (one Mac). Use the unlink flow to release the previous device association.

1. Open Unlink Device and enter the email associated with your license or subscription.
2. Open the unlink link sent to that email address.
3. Select macOS from the available platforms and choose "Confirm Unlink".
4. Once unlinking succeeds, return to Hyud on your new Mac and try activation again with your existing purchase.

If the link is invalid or expired, request a new one. If macOS is not available or you cannot access your purchase email, contact support for help.

Changing an iPhone instead?

For App Store purchases, use the same Apple ID and Hyud account, then restore purchases on the device. This is separate from unlinking your Mac.
