SmartSleep

SmartSleep is one of those “I wish I knew about this earlier” pieces of software that saves me several minutes every day when I put my MacBook Pro to sleep. Intel Mac laptops (and some of the late G4 laptops) have three sleep states: basic sleep, sleep and hibernate, and full-on hibernate. Sleep is the basic low-power mode, and hibernate actually writes the contents of RAM to disk to conserve even more battery power and prevent the contents of RAM from being lost in the event of a power outage. By default, Intel Macs do the latter, and spend 20 to 60 seconds dumping RAM to disk before going to sleep, depending on how much RAM you have installed. If you happen to run your Mac on AC power most of the time, waiting for the disk to spin down can feel like minutes, but SmartSleep lets you safely switch between sleep modes. After setting my MacBook Pro to sleep only, it blinks off and spins down in only a second or two — a huge improvement in sleep time. This “feature” has been bugging me for the last several months, and SmartSleep quickly and effectively adds the system preference that Apple forgot.

  1. Maybe this step is where my MacBook likes to crash? To this day, it still crashes when I close the lid a good 20-40% of the time I’d estimate. The worst is when i lose my MacBook and toss it in my bag. 3 horus later I go to grab my macbook out of my bag and its like 300° in the bag. Or when it happens on AC, it will say closed, and “running” crashed indefinitely.

    Apple should definitely make functionality like this the default. Been using this for a while on my MacBook since switching over from a PowerBook and this solved one of my biggest frustrations with the new Mac.
