I don't know if it's linked to the update – but it started just after I applied it – the cursor jumps about erratically. I tried plugging in a mouse and get the same result. Has this happened to anyone else? I use a MacBook Pro released this year.
 
2010 MBP 13, just install the update early today. Trackpad/Magic Mouse function as per normal. You might wanna do a restore and try installing again??? 😱
 
I have noticed a few times my cursor will jump across the screen lately. My trackpad also doesnt register every click, although that is most likely a mechanical problem.
