  5. Wait for the file to copy, then double click the app in your Applications folder to start it. The first time, you start it, you will see a message that the app is being verified.

  6. Since the app was downloaded from the Internet outside of the app store, your Mac will double check that you meant to run it. Choose Open.

    Important note about alpha and beta releases: Alpha and beta releases of Strange Eons may not be notarized or signed. Notarization involves an additional step in which an app is submitted to Apple for their inspection. Installing an app that isn’t notarized involves some additional steps, for security reasons. If you see a message that “Apple cannot check it for malicious software”, see the next section below for details.

  7. After the file has been copied, you can eject the mounted DMG volume.

Installing unnotarized alpha and beta releases

As mentioned in the note above, alpha and beta releases may not be notarized or signed. These steps should walk you through installing them:

  1. If trying to open Strange Eons shows a warning that “Apple cannot check it for malicious software”, choose OK. Then:
  2. Open System Preferences/Security & Privacy.
  3. If a the padlock in the bottom left is locked (closed), choose it and authenticate your identity to unlock it.
  4. Next to the message about Strange Eons being blocked, choose Open Anyway.
  5. Close System Preferences.
  6. Open Strange Eons. A final warning may appear. Choose Open.
  7. These steps are only required the first time you try to open the app. From now on it will be trusted.

Troubleshooting

Installation problems are rare but frustrating. If the installer fails to start or reports a corrupt file, it usually means that the file did not download correctly. Try downloading it again. If it fails again, it may be corrupt on the server: please report the issue.
