Been away from Macs for quite some time but finally found a great deal on a 13" Air, Haswell model. I am coming from a full HD IPS panel so this screen is not real great but I wanted it due to the long battery life and portability. Planning to keep it until the Air's start using retina panels..if/when that happens. Does Mavericks need any tweaks or is it pretty streamlined out of the box? I'm not having any battery life issues but should I do the OS update that is available as well? Is there any way to darken the text a bit? I've tried using the color calibrater under "Displays" but it didn't do much. Thanks for the help.
