Hardware, How To, Mac OS, Software, Windows20 Comments

While I was fixing my Razer Blackwidow keyboard, I want to keep my PC operating, so I tried to connect the Apple Wireless Keyboard, the pairing process stopped because the Apple Wireless Keyboard can not detect the key entered.

I found a solution, here it is:

  • In Windows 10’s bluetooth settings (can be found in system tray), click on the icon and then click “Add Bluetooth Device”.
  • Then, on the Apple Wireless Keyboard, hold down Command + W, while Windows is searching for bluetooth devices.
  • Then (hopefully) after it finds your Keyboard, it will want to pair with it. Follow the on screen prompts and eventually you will have to type in a pairing code.
  • Type in this code and hit Return.
  • Your Keyboard should successfully pair with Windows 10 via Bluetooth
