What should I do if my Mac keyboard and mouse are not responding?
If your Mac keyboard and mouse are not responding at all, the first thing to check is the connection. If you are using a wireless keyboard and mouse, ensure that the Bluetooth is turned on and that the devices are charged. For wired devices, try unplugging and then plugging them back in. You can also try a different USB port to rule out any port-specific issues.
If the devices are still unresponsive after checking the connections, restart your Mac. Sometimes, a simple reboot can resolve software glitches that may be causing the devices to stop working. If the problem persists even after a restart, consider resetting the System Management Controller (SMC) on your Mac, as this can address hardware-related issues.
How can I reset the SMC on my Mac?
Resetting the System Management Controller (SMC) can help resolve issues with peripherals not functioning properly. To reset the SMC on a MacBook with a non-removable battery, first, shut down your laptop. Then, press and hold the Shift, Control, Option keys on the left side of the built-in keyboard, and the power button simultaneously for about 10 seconds. Release all the keys and turn your Mac back on.
For desktop Macs, the process is slightly different. Shut down your Mac and unplug the power cord. Wait for about 15 seconds, then plug the power cord back in and wait for 5 seconds before turning it back on. After resetting the SMC, check to see if your keyboard and mouse are functioning properly again.
Why is my Mac keyboard and mouse working intermittently?
Intermittent functioning of your Mac keyboard and mouse can often be attributed to weak batteries or Bluetooth connectivity issues.
