If the pointer doesn’t move when using the trackpad with Mac
If the pointer doesn’t move when you use the trackpad on your portable Mac, make sure you’re using only one finger on the trackpad. Depending on the type of portable Mac you have and the options you set in Trackpad preferences, using more than one finger on the trackpad may not move the pointer.
To see the options, choose Apple menu > System Preferences, click Trackpad, then click Point & Click.
If there is an “Ignore accidental trackpad input” checkbox in Trackpad preferences and it’s selected, using two fingers on the trackpad doesn’t move the pointer.
On some portable computers, you can use two fingers on the trackpad to scroll in windows that have scroll bars. If your Mac has this feature, you can’t use two or more fingers to move the pointer.
If the trackpad is still not working, your Mac may be showing a low battery alert that you can’t see. Connect your Mac to an electrical outlet or connect an external keyboard to see the alert.
If you still have difficulty, you may have a problem with your hardware. See an Apple Authorized Service Provider.
