What to do
- Check About This Mac > Storage to confirm you have enough free space for the app.
- Check Apple's System Status page from another device to rule out an App Store outage.
- Sign out of the App Store (System Settings > [your name] or App Store menu) and sign back in.
- Check your internet connection stability, especially if downloads consistently stall partway through.
- Restart the Mac and try the download again.
- Pause and resume the download from the App Store's download indicator (in the Dock or Launchpad) if it appears stuck.
- Check for macOS updates, since some App Store issues are tied to outdated system software.
- If a specific app consistently fails while others work fine, check that app's own reviews or support page for known issues.
