Wireless keyboard not connecting
I've got an Apple wireless keyboard (I don't think it's magic because it's got the round power button on the side), and it gets discovered by my MacBook Air, but when I click connect, it says it's not able to. I've connected another wireless keyboard and mouse before, so I don't know what's wrong! The Apple keyboard has been paired to stuff before, but what it's been paired to is currently in a different country, so it's really not connected to that. Any advice??
MacBook, macOS 10.13
