Optimization for Mac OS X with SSD
To reduce disk writing, I have made some changes after Google the solution. Sleeping mode Check default value $ sudo pmset -g | grep hibernatemode hibernatemode 3 Change value $ sudo pmset -a hibernatemode 0 Remove sleep image $ sudo rm /var/vm/sleepimage Sudden Motion Sensor $ sudo pmset -a sms 0 Spotlight $ sudo mdutil -a -i off Hard drive sleep Go to "System Preferences" -> "Energy Saver" uncheck "Let disk fail sleep when possible" Hope that could helpful.
