i cant type anything

Hello Yoli105,

Thanks for stopping by Apple Support Communities.

For help with your keyboard for your Mac follow the steps below to see if we can get the keys working as expected.

"If no keys work on an external keyboard

• Disconnect and reconnect the keyboard. Make sure the connector is completely inserted into the port.
• Connect your keyboard to a different USB port or to a different Mac. If this solves the problem, your Mac may need to be repaired. Contact Apple or an Apple Authorized Service Provider for service. Repairs performed by untrained individuals or using non-genuine Apple parts may affect the safety and functionality of the device.
• Connect a different keyboard to this Mac. If this solves the problem, you may need to take your keyboard in for service.

If other keys don’t work

You may have accidentally set an option that changes how your keyboard operates.

• Choose Apple menu  > System Settings, click Accessibility  in the sidebar, then click Keyboard on the right. (You may need to scroll down.) Make sure Slow Keys is turned off. If Slow Keys is on, you must press and hold a key longer than usual before it’s recognized.
• Choose Apple menu > System Settings, click Accessibility in the sidebar, then click Pointer Control on the right. (You may need to scroll down.) Make sure Mouse Keys is off.
• Choose Apple menu > System Settings, then click Keyboard  in the sidebar. (You may need to scroll down.) Click Edit next to Input Sources on the right, then turn on “Show Input menu in menu bar.” Open the Input menu, then make sure the correct keyboard layout is selected."
