MacBook Air won't recognize Apple mouse
Tried rebooting, insuring Blue Tooth is on. Mouse works on iMac desktop.
MacBook Air, macOS 14.4
Your MacBook Air should be running the latest version of macOS, as updates often include fixes for connectivity issues. Check your version. Also, you can try to forget and re-pair the mouse. Just click the "X" next to the mouse in the Bluetooth preferences to forget the device. Then put the mouse in pairing mode and connect it again.
