What should I do if my USB keyboard is not recognized by my Mac?
If your USB keyboard is not recognized by your Mac, the first step is to check the physical connection. Ensure that the keyboard is properly plugged into the USB port. Try unplugging it and then plugging it back in, or testing it in another USB port. If your Mac has USB-C ports, make sure you are using the correct adapter, if necessary.
If the keyboard still isn’t recognized, restart your Mac. Sometimes a simple reboot can resolve the recognition issue. If it still doesn’t work after rebooting, consider testing the keyboard with another device to verify that it’s functioning. If it works with another computer, the issue may lie with your Mac’s software or settings.
Why is my keyboard lighting up but not typing?
If your USB keyboard lights up but does not respond to typing, this could indicate that the keyboard is being recognized by your Mac, but there may be a software issue preventing it from functioning correctly. First, check the Keyboard preferences in System Preferences to ensure the correct keyboard layout is selected. You can also toggle the “Use F1, F2, etc. keys as standard function keys” option to see if it makes a difference.
Another potential troubleshooting step involves resetting the PRAM or NVRAM on your Mac. This can sometimes fix keyboard-related issues by resetting certain system parameters.
