USB devices keep disconnecting from Mac randomly
A USB cable that's loose or damaged is the most common cause. Check that the cable is pushed in firmly at both ends. If that doesn't fix it, the cable itself can be bad and needs replacing. Bad cables cause almost all USB disconnection issues.
When USB devices keep disconnecting, it's almost always the cable between your device and your Mac that has a loose connection or is damaged. Occasionally it's a power issue or a port that needs cleaning. We'll check the physical connection first, then test different ports and cables to isolate the problem.
Fix-IT-Bot will walk you through each step — just tap, no typing needed.
