Where is a Mac Application's NSUserDefaults Data Stored?

I am using NSUserDefaults to store some data in my application.

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:@"dummy string" forKey:@"lastValue"];
[prefs synchronize];

For testing purposes I need to see the System Preferences plist file where my NSUserDefaults data is saving on the Mac.

I know where the iOS application user defaults are stored, but I don't know about mac application. Where is a Mac Application's NSUserDefaults Data Stored?

Solution 1:

They can be found in more than one place:

~/Library/Preferences/com.example.myapp.plist
~/Library/SyncedPreferences/com.example.myapp.plist

and if sandboxed

~/Library/Containers/com.example.myapp/Data/Library/Preferences/com.example.myapp.plist
~/Library/Containers/com.example.myapp/Data/Library/SyncedPreferences/com.example.myapp.plist

Solution 2:

In ~/Library/Preferences/com.example.myapp.plist.

Solution 3:

(Xcode 7.3.1,macOS 10.11.6)

For Additional,if you are using App Groups

    if let prefs = NSUserDefaults(suiteName: "group.groupApps")  {
       ...
    }

plist file will be here:

~/Library/Group Containers/group. groupApps/Library/Preferences/group.groupApps.plist

Solution 4:

On Sierra, I found the data here: ~/Library/Application Support/.
