It’s a better idea to simply disconnect all USB devices and try connecting the Bluetooth mouse or keyboard again. If, in case, you’re using a wired mouse or keyboard, reconnect it to check for the issue.

  • So, release the Shift key when you see the Apple logo on the screen or the login screen.
  • Next, you can try connecting the Bluetooth Mouse or Keyboard to check for the issue. If the problem gets fixed that means there is an issue with the third-party program or settings on the device.
  • Make sure to try finding out the conflicting settings and fixing the same or delete the newly installed third-party program.

Try to unplug your wired keyboard or wired mouse from the current USB port of the Mac Studio and then try connecting the USB cable to another port. Sometimes issues with the proper connection to the port can trigger the device not to recognize or not appear problem. In some cases, a faulty or damaged USB cable of the peripheral device can also occur such issues. While loose connectivity or a faulty USB port can be a reason.

17. Check the System Report for USB (Wired Only)
