A big part of my recent upgrade to a Western Digital Scorpio Black 500GB hard drive was deciding to leave my old Mac setup behind. I started with a fresh install of OS X Lion this time around, and one of the things I had forgotten I’d tweaked (all the way back in 2009) was the time it took for my MacBook Pro to go to sleep. By default, putting a Mac like mine to sleep takes about 15–20 seconds, which is really more akin to hibernation than quickly going to sleep for transit.
However, thanks to a tip from Lifehacker that I picked up years and years ago, I’ve managed to get rid of ten seconds of digital tossing and turning. A quick terminal command de-activates the “safe sleep” in OS X that writes all of the contents of your RAM (8 GB, in my case) to your hard disk, so sleep comes much faster. Four or five seconds after shutting the lid on the MacBook Pro, in my case. That’s a much more reasonable time frame, and this change is well worth looking into if you’re the type who tends to use your MacBook Pro on-the-go.
