If your device is not recognized, follow these steps: Check macOS Version: Ensure that your macOS version is 10.13 or later. If it's lower, update your system. Reconnect the Cable: Thunderbolt ports may accumulate dust or oxidize over time. Try unplugging and reconnecting multiple times or using a different port. Verify SSD Compatibility: This enclosure supports most major SSD brands. If the SSD is not recognized, try another SSD. Check for Motherboard Issues: If all else fails, your Mac's motherboard may be faulty and require repair. Usage Notes Since the Thunderbolt cable handles both data transfer and power supply, avoid moving the device while using it with a MacBook to prevent unstable connections. When used with an iMac, it is recommended to secure the enclosure to the back of the machine with double-sided tape to prevent disconnection issues.
