If you have a separate numeric keypad on your keyboard, the Num Lock key is located in the numeric keypad. If you’re using a portable Mac, Num Lock is sometimes a function key, marked Num Lock. If your keyboard has a separate keypad but no Num Lock key, try pressing Shift-Delete.
If the numeric keypad still doesn’t work as you expect, you may have enabled Mouse Keys, which lets you move the pointer with the keypad.
To see the option that turns off Mouse Keys, choose Apple menu > System Preferences, click Accessibility, then click Mouse & Trackpad.
