Hi to all! I created an account just to ask this! I'm measuring the time it takes my MacBook Pro Mid 2012 to go to sleep when I close the lid! The time that passes from the point of closing the lid and when the standby light starts to strobe is between 46 seconds and 1:15 minutes. I know this is still a beta! but what has been your experience with this on your mac's? FYI: My "pmset -g" the "hibernatemode 3" is in it's defaults. UPDATE: When I set in terminal "pmset -a hibernatemode 0" to not store the memory on "/var/vm/sleepimage" the time it takes is about 34 to 40 seconds. If this is a common behavior! I guess we will have to wait for the next release.
