On Mac OS X, some windows are a fixed size (eg. Photo Booth). Is there a way I can make them smaller to take up less space on a smaller screen?
Actually there is a solution:
Before launching an app, run from terminal: defaults write -g AppleDisplayScaleFactor 0.8 That will make all subsequent apps run at 80% size (you can set it back to 1 after it is launched).
To make this easy, create the following apple script (I turned it into an .app and gave it the icon for photobooth):
do shell script "defaults write -g AppleDisplayScaleFactor 0.8" tell application "Photo Booth" to launch do shell script "defaults write -g AppleDisplayScaleFactor 1"
I believe the answer is no.
The only thing that may help is simply increasing your screen resolution.
Not a great answer, but I really don't think it's possible.
Update: See Michael Neale's response below for a really slick solution.
But there are some alternatives:
