Disable Application Downloaded from Internet Warning

To disable the warning, use the xattr delete command:

xattr -d -r com.apple.quarantine /application/path/here

I downloaded Firefox from Chrome and was presented with the “application downloaded from the internet” warning every time I opened Firefox. To get rid of the warning, I ran the following command from the terminal:

sudo xattr -d -r com.apple.quarantine /Applications/Firefox.app

The xattr command manages attributes on files. The -d flag indicates that the com.apple.quarantine attribute should be deleted. The -r flag indicates that the attribute should be removed recursively from all files in the designated directory.

Sound when charging connected

Usually, Mac is silent when the charger is connected. If you want, you can turn on the sound for this action, similar to what your iPhone publishes. It is enabled by the following command:

defaults write com.apple.PowerChime ChimeOnAllHardware -bool true; open /System/Library/CoreServices/PowerChime.app &

If you want to return everything as it was, open the Terminal, insert this code there and press Enter.

defaults write com.apple.PowerChime ChimeOnAllHardware -bool false;killall PowerChime
