“Android File Transfer” application starts automatically in Mac OS X when you plug your Android device to the USB port. Even if you only want to charge it.

This are the steps you have to take to avoid this (annoying) behaviour:

1. Open the “Activity Monitor” and kill the “Android File Transfer Agent” process.
2. Open “System Preferences” > “Accounts”. Go to the “Login Items” tab of your user. Remove the “Android File Transfer Agent” (I didn’t have this item anyway).
3. Find your “Android File Transfer.app” file (usually in /Applications):
   • Right click (or ctrl+click) on it and select “Show package contents”.
   • Go to Contents/Resources.
   • Rename “Android File Transfer Agent.app” to e.g. “Android File Transfer Agent_DISABLED.app“.
4. Go to /Users/username/Library/Application Support/Google/Android File Transfer (you can open Library folder from the terminal running “open ~/Library”) and rename “Android File Transfer Agent.app” to e.g. “Android File Transfer Agent_DISABLED.app“.

Now “Android File Transfer” won’t auto-start when you plug your phone on the USB port, but if you open it manually everything will work just fine.
