Connecting via USB Instead of Bluetooth

If the error persists, try connecting your tablet to your Mac using a USB cable instead of Bluetooth. This can help rule out any potential Bluetooth-related issues.

If your tablet is still not recognized, the issue might not be with the tablet itself, but with your Mac's USB ports or cable. Try using a different USB cable and connecting your tablet to a different USB port on your Mac.

Running First Aid in Disk Utility

Sometimes, a corrupt system file might be causing the issue. To check for any disk errors, open "Disk Utility" on your Mac, select your startup disk, and click on "First Aid". This will check your disk for any errors and repair them if possible.

Remember, using First Aid won't delete any of your personal data, but it's always a good idea to back up your files before running any utility tools.

If you've tried all these steps and your Mac still fails to recognize your tablet, it might be time to visit an Apple Store or contact Apple's customer support. They can provide further assistance and guide you on what to do next.
