Turn Off Resume on a Per App Basis in Mac OS X Lion with defaults write

In our post on how to disable Resume for Safari or other applications in OS X 10.7, several of our commenters pointed out that it isn’t necessary to change the individual app directories permissions. Alternatively, you can turn off Resume on a per-app basis using a defaults write command entered into the Terminal.
Turn Off Resume on a Per App Basis
Here are a few example defaults strings for individual applications, and then we’ll show you how to find your own strings for other applications:
Turn Off Resume for Safari
defaults write com.apple.Safari NSQuitAlwaysKeepsWindows -bool false
Turn Off for Google Chrome
defaults write com.google.Chrome NSQuitAlwaysKeepsWindows -bool false
Turn Off for QuickTime Player X
defaults write com.apple.QuickTimePlayerX NSQuitAlwaysKeepsWindows -bool false
Turn Off for Preview
defaults write com.apple.Preview NSQuitAlwaysKeepsWindows -bool false
You will want to relaunch whatever application you have disabled the feature for in order for changes to take effect.





One of the many understated features in Mac OS X is the ability to natively convert audio to m4a directly in the OS X Finder – without any additional downloads or add-ons. Yes, an MPEG audio encoder is built directly into Mac OS X since versions 10.7 and 10.8, 10.9, 10.10 (and beyond of course), meaning you can convert audio directly on your desktop without using any other apps, and without buying anything else, because the encoder is free and bundled in Mac OS. 









The Mac has an autocorrect feature that can range from excellent to annoying, and it works by attempting to automatically correct typos and misspellings of words as they appear, which are instantly compared to an extensive dictionary and replaced on the fly. It can be a great feature but it’s not perfect, and how you feel about auto-corrections really depends on what you’re trying to type, how often you make typos, and what your individual experience is with the corrections themselves, much of which can depend on typing habits themselves.
