How to fix the Jerky and jumpy Apple Magic Trackpad behavior? My Apple Magic Trackpad has started to move the pointer on the screen with a jerky and jumpy way, that makes it difficult to use it (compared with the macbook pro mid 2010 17inch touchpad).
How can I fix it, and why it appeared so suddenly?
My operating system is Mac OS Mountain Lion.
Thank you.
For me, turning Bluetooth off then back on did the trick for a very jerky cursor. Turning the trackpad off and on did not fix it.
