Step by step

1. 1 min

   Verify application compatibility

   Open System Settings and navigate to General > About to ensure your macOS version supports your migrated software. Check the developer's website for specific silicon architecture requirements if migrating from an Intel-based Mac. Confirm that your apps are not marked with a crossed-out circle icon in the Applications folder.

   Note: Apps marked with a circle icon require a reinstallation of the latest version compatible with your current macOS.

   Update migrated apps via App Store

   Launch the App Store from the Dock or Applications folder. Click on your profile icon in the bottom-left corner to view your purchased applications.

   Redownload missing or corrupted applications

   If an application fails to launch, move the corrupted version to the Trash. Navigate to your Purchased tab in the App Store, click the cloud download icon next to the specific app, and wait for the fresh installation to complete. This process pulls a clean binary directly from Apple's servers.

   Note: A fresh download is always safer than moving legacy application files manually.

   Restore library support files

   Migration assistant often leaves configuration files in the User Library. Navigate to Finder, select Go from the menu bar, and hold the Option key to reveal the Library folder. Check ~/Library/Application Support/ to ensure the folder corresponding to your reinstalled application exists and contains the necessary configuration data.

   Note: Paste ~/Library/Application Support/ into the dialog box for direct access.

   Authorize third-party software

   Apps installed outside the Mac App Store often require re-authentication. Launch the application and provide your credentials when prompted. If the app fails to open, go to System Settings > Privacy & Security and look for a notification stating that software from an identified developer was blocked; click Open Anyway to authorize it.

   Note: Only authorize applications from developers you trust.

Check your Login Items in System Settings > General > Login Items to remove any legacy helpers from your previous machine.
