So i just updated my Macbooks air mid-2011 to Mavericks. And now i'm experiencing trouble with my sleep-mode/hibernate-mode. Before updating, i used this terminal code: sudo pmset -a hibernatemode 1 To change the sleeping behaviour on the mac. And the mac was set to hibernate instead of the regular sleep mode. 1 is the setting for hibernate-mode.Because its using too much power while sleeping. About 20% is going to waste while its in sleep mode, even tho the wifi and internet sharing is turned off. Does anyone know a way to change the behavour to hibernate-mode? Iv'e tried to reenter the terminal code, and its apparently not working. Looking forward to hear some solutions from you guys..
