Lenovo wireless keyboard doesn't work with MacBook Pro

Hey Estebitas20,

If we understand correctly, the Bluetooth keyboard is not working with the Mac. One thing you can do is to remove the device then pair with it again.

Is it connecting to the Mac?

Does the keyboard work in any app?

"Remove a Bluetooth device from your Mac

If you want to remove (unpair) a Bluetooth device from your Mac's device list, follow these steps:

1. Choose Apple menu > System Preferences, then click Bluetooth.
2. Hover the pointer over the device you want to remove, then click the button  that appears next to the device's name.

After you remove a Bluetooth device, you'll have to repeat the pairing process if you want to use it again."

Using a Bluetooth mouse, keyboard, or trackpad with your Mac

Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.

Thank you for using Apple Support Communities. Have a good one.
