My kids want to use my Hackintosh netbook – a Lenovo Ideapad S10-2 running Snow Leopard. One of the great things about OS X is its excellent built-in parental controls, but on a netbook with a small 600 pixel-high screen, the buttons for setting them up are off the screen.
I tried using an external monitor – with amusingly mad and useless results… then I found this trick. Open up a Terminal window and type
defaults write -g AppleDisplayScaleFactor 0.8
This makes the next window you open small enough to see the required buttons. Set up the parental controls, type
defaults write -g AppleDisplayScaleFactor 1
in the Terminal command line.
