Say if I clicked open 10 image files, and 2 PDF files, and quit Preview, then next time when I click on 1 image file or just start Preview, all those 12 other windows will open too... I was playing a clicking game to close them one by one... is there a quick way to make Preview not do that or "Close All"? (while keeping other apps to open the previous state).
As an alternative to RestoreMeNot, you can run a command like this in Terminal:
defaults write com.apple.Preview NSQuitAlwaysKeepsWindows -bool false
If others search for how to disable restoring state for all applications, enable this option:
I have disabled restoring state from System Preferences but enabled it just for Safari:
defaults write com.apple.Safari NSQuitAlwaysKeepsWindows -bool true
