You can either use an app or the command-line.
The Supercharge app (paid) makes it easy to import/export settings for any apps.
For the next steps, you will need to be familiar with the command-line.
You first need to find the bundle identifier of the app. Replace AppName
with the app's name and run the following command:
osascript -e 'id of app "AppName"'
Then run the following command with the correct bundle identifier and app name:
defaults export BUNDLE_IDENTIFIER APP_NAME.plist
Example:
defaults export com.sindresorhus.Velja Velja.plist
You now have a Velja.plist
file with all the data and settings for this app. You can either store this file in a safe place as a backup or use it to import the settings into another computer.
Make sure the app is not running.
Run the following command:
defaults import BUNDLE_IDENTIFIER APP_NAME.plist
Example:
defaults import com.sindresorhus.Velja Velja.plist
Then restart your computer to ensure the settings are correctly applied.
