"4/5 mice" - MacWorld
Sleep your Mac differently depending on the battery level.
Works fine on Mavericks and Lion, but READ ON...
The current update of SmartSleep has not been approved by the AppStore team yet.
To ensure compatibility you must download the current Mountain Lion compatible version from my website.
Features
--------
* QuickSleep feature *New* - sleep your Mac immediately the way you want.
* SmartSleep Menu Item *New* - figure out the current Sleep State and QuickSleep.
* Insomnia feature in Menu Item *New* to keep your Mac awake
* Five different sleep modes to chose from:
- system default
- smart sleep (if your Mac has a battery )
- sleep only
- hibernate only
- sleep and hibernate
* Does not need admin privileges *New*
- You do not need to have SmartSleep in your Dock to keep it running as you can enable to run it as a loginItem in the preferences.
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 & 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 lose the ability to change the battery as the battery is needed to keep the contents of the memory (RAM).
Just sleep and hibernate will wake the computer fast, but sleeping will take ages as the contents of the memory are saved to disk before entering the sleep.
The solution
SmartSleep lets you select each sleep state. Additionally the new SmartSleep state lets your notebook just sleep while the battery has a high level. If the battery level drops below a certain point (default is less then 20% or 20 minutes) it will switch to sleep and hibernate. So you have the best of both worlds. Furthermore it will expand the lifetime of your SSD (if you have one) as your MacBook wont write a hibernate file as often.
Background
----------
Back in 2005 a feature called hibernate silently went into newer PowerBooks. With an nv-ram setting it was possible to enable hibernation on old Powerbooks as well. A friend of mine pointed this out to me and having done no Cocoa programming at all on Macs I decided to venture into this realm and write a nice interface to it - Hibernate.prefPane was born.
I quickly found out that hibernation wasn’t a feature I wanted and the program lay dormant for two years.
When I bought an Intel MacBook Pro I was annoyed by the hibernation feature which just takes too long to get my Mac to sleep. I updated Hibernate but that was not enough, so I decided to write SmartSleep.
