If your OWC Mercury Elite Pro is not recognized by your M4 MacBook Pro when connected via USB, consider the following troubleshooting steps:
1. Check Cables and Ports – Ensure all cables are securely connected. Try using a different USB cable or port to rule out connection issues. 2. USB Compatibility – The OWC Mercury Elite Pro Quad supports USB-C and includes a USB-C to USB-A cable for compatibility with older machines. Verify that your MacBook Pro supports the connection type being used. 3. Disk Utility Check – Open macOS Disk Utility to see if the drive is detected. If it appears but is not accessible, try using Repair Disk and Repair Permissions in Disk First Aid. 4. Formatting Issues – The drive may be formatted using a partition scheme incompatible with your Mac. If necessary, reformat it using Mac OS Extended (Journaled) or APFS in Disk Utility. 5. Power and LED Indicators – Check if the drive's LED indicator lights up when connected, which confirms power and activity. 6. Try Another Computer – Connect the drive to another Mac or Windows PC to determine if the issue is specific to your MacBook. 7. Software Conflicts – If using RAID configurations, ensure that required drivers or software (such as SoftRAID) are installed and compatible with macOS. 8. Firmware or macOS Updates – Ensure your MacBook Pro is running the latest macOS version, as updates may improve hardware compatibility.
If the drive is still not recognized after these steps, contact OWC Technical Support for further assistance.
