Virtually increase your Screen Resolution on OSX
Here is a handy terminal command to virtually increase your screen resolution (definitely useful on Netbooks running OSX86):
defaults write -g AppleDisplayScaleFactor scale factor
You could use for instance:defaults write -g AppleDisplayScaleFactor 0.75
Note that the change only affects applications when they are launched.
And to make this permanent:defaults write NSGlobalDomain AppleDisplayScaleFactor 0.75
In case you want a particular application to be scaled down (E.q. Photoshop), use:defaults write com.adobe.photoshop AppleDisplayScaleFactor 0.75
To go back to normal, use (then logout/login):defaults write -g AppleDisplayScaleFactor 1
