Wondering if anyone has feedback on how 10.10.1 has been on their late-2011 MacBook Pro. I had 10.10 installed upon release and it killed my battery life with constant CPU utilization (>80% in Activity Monitor). I have since been back on Mavericks but lately want to go back, and really do not want to deal with the hassle of downgrading to Mavericks again since restoring by media hard disk via USB 2.0 is pretty painful. Was wondering if anyone had the issue but had it resolved with the update, or if I should just hold out for 10.10.2. Thanks!
