My cursor suddenly changed shape from normal to a capital i shape and won't engage. I don't know how to change it back. PLEASE can someone help??
Mouse or trackpad?
Hold down the option key and go to Finder/Go and select your Library. Then go to Preferences and delete either the com.apple.driver.AppleBluetoothMultitouch.trackpad.plist or the com.apple.driver.AppleHIDMouse.plist (whichever is applicable).
Log out/in or restart and test.
