If your external hard drive is not showing up on your Mac, you can use the Disk Utility program to troubleshoot and resolve the issue. Follow these steps:

1. **Open Disk Utility:** Go to "Finder" -> "Applications" -> "Utilities" -> "Disk Utility."

2. **Check for the External Drive:** Look for your external hard drive in the left sidebar of Disk Utility.

3. **Unmount and Remount:** If the drive is mounted, unmount it and then remount it to see if it appears.

4. **Format the Drive:** If the drive is still not recognized, you may need to format it. Be aware that formatting erases all data on the drive, so ensure you have a backup.

5. **Use Disk First Aid:** Disk Utility includes a "First Aid" option. Select your external drive and run First Aid to check and repair disk errors.

Remember to check the external drive's connection, use different USB ports, and ensure the drive is powered on. If issues persist, consider checking for compatibility or updating your macOS version[1][8].
