When looking at the macbook air 4-2 install guide, there is a reference to a post install script. This wiki seems outdated, so I didn't want to run the script after I'd installed Trusty Tahr. I'm mainly interested in the GPU power save parts of the script, as I'd like to maximize battery life.
Should I run this script?
If I only want to run the GPU power saving parts, is that a good idea?
Are there other resources (or perhaps other scripts) that I can run to help maximize battery life?
