MBP Early 2011 on DP 4. About four hours after each boot, a process called "systemstats" starts to use an insane amount of resources - 4.1 GB of my 8 GB as well as 100% of CPU. Evidently this is the process that collects power usage data, and I am forced to force quit it in Activity Monitor to have a usable computer again. Did anyone else have this problem or know how to fix it? Thanks.
