1. Did the 2011 MacBook Pro get Power Nap with mavericks? Every time I open my lid from sleep, my mail is already downloaded and there is a notification on the lock screen instantaneously stating that I have n number of unread mails 2. I loved having the RAM dock icon on activity manager. This seems to have disappeared - any way to get it back? 3. My predicted battery life at 90-100% battery left with no apps using sig. power shows around 3 hours. ML generally shows 5 hours and was quite accurate. Shouldn't it be the other way around?
