How to get Bundle ID of Mac application?

Question

I want to use Python and atomac module to trigger an application in macOS like following scripts:

atomac.launchAppByBundleID()
app_win = atomac.getAppRefByBundleId(app_bundle_ID)

But I don't know how to get the Bundle ID (app_bundle_ID) of the application.

Answer 1

As we know, bundle id is located in the info.plist of an app, so both PlistBuddy and defaults could help

/usr/libexec/PlistBuddy -c 'print CFBundleIdentifier' /Applications/Xcode.app/Contents/Info.plist
or
defaults read /Applications/Xcode.app/Contents/Info.plist CFBundleIdentifier

which prints

com.apple.dt.Xcode

Answer 2

if you just need it to launch the app look in the app's info.plist file. the file is in the app bundle in the Contents directory. This works for a lot of apps.

Answer 3

I use two methods to get the bundler ID:

osascript -e 'id of app "SomeApp"'

and

mdls -name kMDItemCFBundleIdentifier -r SomeApp.app
