What are common symptoms of a USB port issue on my MacBook Air?
A common symptom of a USB port issue is when external devices, such as USB drives or mice, fail to be recognized by your MacBook Air. You might notice that the device does not show up in Finder or on your desktop, which can be frustrating. Sometimes, the device may connect momentarily before disconnecting again, indicating a possible intermittent fault.
Another symptom can be the USB port itself not displaying power. When you plug in a device, there should be a visual indication, like LED lights on the device, that it is powered and communicating with your MacBook. If these lights are off and nothing happens on your screen, it may indicate a problem with the port or the device itself.
How can I tell if the problem is with the USB port or the device?
To determine whether the issue lies with the USB port or the connected device, try using the device on another computer. If it works on a different system, this suggests the device is functioning properly, directing your focus to the USB port. Conversely, if the device fails to work on another computer as well, the issue is likely with the device itself.
You can also try connecting different USB devices to your MacBook Air. If other devices are recognized and work fine, this points to a problem with the original USB device. However, if multiple devices aren’t recognized regardless of which one you plug in, the USB port on your MacBook may be at fault and requires further inspection.
