I'm on OSX Lion and this is driving me crazy. Whenever i watch a video in quicktime and close it, then open another video, the previous video that i played also comes up.

Is there a way to not have the previous video(s) come up when opening quicktime besides closing out the windows, then quitting, everytime?

That feature is part of Lion and QuickTimeX, but you can disable it.

Open your terminal (/Application/Utilities/Terminal.app) or use Spotlight to find the Terminal and type:

defaults write com.apple.QuickTimePlayerX NSQuitAlwaysKeepsWindows -bool false

That should stop QuickTime from saving the opened windows when you quit it.

If you want to revert the behavior, change the "false" to "true".


The above answer did not work for me. But the commands below worked:

defaults write com.apple.QuickTimePlayerX NSRecentDocumentsLimit 0
defaults write com.apple.QuickTimePlayerX.LSSharedFileList RecentDocuments -dict-add MaxAmount 0

You can run these commands in the Terminal(/Application/Utilities/Terminal.app or using the Spotlight).
