SmartSleep is a preference pane that dynamically sets the sleep state of your machine. It's a successor to Hibernate.prefPane.

The Problem - Your MacBook or MacBook Pro knows the following sleep states:

  • sleep: machine will go to sleep only (saves state in RAM only, battery keeps RAM contents)
  • sleep and hibernate: machine sleeps and hibernates. (default)
  • hibernate only: machine will go to hibernate only. (saves state on disk, battery will not be used)
  • Just sleep means that the notebook will go to sleep fast, but you loose the ability to change the battery as the battery is needed to more...

What's New

Version 3.22:
  • Added default overrides for pmset. SmartSleep uses pmset to set the values for sleep, hibernate, sleep and hibernate and system default. You can now override the values that SmartSleep uses:
    • pmsetvalueforsleep
    • pmsetvalueforsleepandhibernate
    • pmsetvalueforhibernate
    • pmsetvalueforsystemdefault
  • Added Retina menu-bar icons - thanx to more...


  • OS X 10.6.8 or later
