I have an old 2013 IMAC that, recently, does not connect to any USB or Bluetooth keyboards or mice, meaning I cannot get farther than the login screen. I have double checked, and all of the USB options I have used work perfectly fine on my other devices. Any ideas?
iMac Line (2012 and Later)
Reset the SMC as per > https://support.apple.com/en-us/HT201295
Desktop computers
Then try connecting a USB Keyboard and Mouse to the iMac.
Also note that wireless Keyboards and Mice, can only be paired with one device at a time. Meaning that it must be unpaired from the current device, before it can be paired with a different device.
