UPDATE: Apple released an update that resolves an issue in which the "Unlock Drive for Mac" application cannot be opened. To resolve this issue, update to macOS 15.4 or higher. If unable to update to 15.4, then the steps below will still allow the drive to be accessed.
ISSUE: When trying to unlock a locked drive on macOS 15 (Sequoia) the following message may appear.
It is important to know that there is nothing wrong with the drive. This message occurs because of an issue opening the application “Unlock Drive for Mac” located on the drive. For these situations, please install Toolkit and use Toolkit to unlock your drive and access your data.
Install Toolkit and a prompt should appear to unlock the drive when security is enabled.
If the prompt doesn’t appear automatically when you connect the drive:
- Open Toolkit
- Click Seagate Secure on the main menu
- Click Unlock
- Enter your password
- Click Continue
If you experience issues unlocking using Toolkit, physically disconnect and reconnect the drive, then try the steps again.
