Ever since downloading osx Mavericks , my mac book keeps on crashing every few minutes. Doesn't matter what application I am using, system hangs every few minutes. I have been looking at Activity monitor closely. Following programs end up using a lot of CPU and hang a lot: SystemUIServer ( not responding -- several times ) Google Chrome ( not responding -- several times ) Google Chrome Helper ( not responding -- several times ) PepperFlashPlayer ( not responding -- several times ) Windows Server ( not crashing -- but using a lot of CPU resources - remains at top 5 CPU usage tasks. ) Looking at Console app .. following programs cause a lot of crashes: ( Console itself was not responding several times I was looking at it ) systemstatsd ( almost all of the crash reports are related to this ) GoogleChromeHelper Here is a screenshot of a hang: https://docs.google.com/file/d/0B_Kk3cC-uY8WZy1VV3dRWlJXMW8/edit?usp=sharing ( please look at the console part of the screenshot and see the huge number of crash reports I have had just today ) Majority of these crash reports are being caused due to "systemstatsd" ( well that is the name that appears on almost all of the crash reports ) I also ran EtreCheck program .. here is the output: Hardware Information: MacBook Pro (13-inch, Mid 2009) MacBook Pro - model: MacBookPro5,5 1 2.26 GHz Intel Core 2 Duo CPU: 2 cores 8 GB RAM Video Information: NVIDIA GeForce 9400M - VRAM: 256 MB Audio Plug-ins: BluetoothAudioPlugIn: Version: 1.0 AirPlay: Version: 1.9 AppleAVBAudio: Version: 2.0.0 iSightAudio: Version: 7.7.3 Startup Items: ChmodBPF - Path: /Library/StartupItems/ChmodBPF System Software: OS X 10.9 (13A603) - Uptime: 0 days 12:48:1 Disk Information: FUJITSU MJA2160BH FFS G1 disk0 : (160.04 GB) EFI (disk0s1) <not mounted>: 209.7 MB Macintosh HD (disk0s2) /: 159.18 GB (116.26 GB free) Recovery HD (disk0s3) <not mounted>: 650 MB MATSHITADVD-R UJ-868 USB Information: Apple Inc.
