AppleScript and JXA scripts to get Now Playing info. Works on macOS 15.4+, including macOS 26 beta 1.

now-playing.js

function run() {
	const MediaRemote = $.NSBundle.bundleWithPath('/System/Library/PrivateFrameworks/MediaRemote.framework/');
	MediaRemote.load
	
	const MRNowPlayingRequest = $.NSClassFromString('MRNowPlayingRequest');
	
	const appName = MRNowPlayingRequest.localNowPlayingPlayerPath.client.displayName;
	const infoDict = MRNowPlayingRequest.localNowPlayingItem.nowPlayingInfo;
	
	const title = infoDict.valueForKey('kMRMediaRemoteNowPlayingInfoTitle');
	const album = infoDict.valueForKey('kMRMediaRemoteNowPlayingInfoAlbum');
	const artist = infoDict.valueForKey('kMRMediaRemoteNowPlayingInfoArtist');
	
	return `${title.js} — ${album.js} — ${artist.js} | ${appName.js}`;
}

now-playing.scpt

use framework "AppKit"

on run
	set MediaRemote to current application's NSBundle's bundleWithPath:"/System/Library/PrivateFrameworks/MediaRemote.framework/"
	MediaRemote's load()
	
	set MRNowPlayingRequest to current application's NSClassFromString("MRNowPlayingRequest")
	
	set appName to MRNowPlayingRequest's localNowPlayingPlayerPath()'s client()'s displayName()
	set infoDict to MRNowPlayingRequest's localNowPlayingItem()'s nowPlayingInfo()
	
	set title to (infoDict's valueForKey:"kMRMediaRemoteNowPlayingInfoTitle") as text
	set album to (infoDict's valueForKey:"kMRMediaRemoteNowPlayingInfoAlbum") as text
	set artist to (infoDict's valueForKey:"kMRMediaRemoteNowPlayingInfoArtist") as text
	
	return title & " - " & album & " - " & artist & " | " & appName
end run

Hey do you know if there is any way to know if the track is playing or if it's paused?

@Pen7art You can use the kMRMediaRemoteNowPlayingInfoPlaybackRate key, which is 0 when paused and 1 when playing.

const isPlaying = infoDict.valueForKey('kMRMediaRemoteNowPlayingInfoPlaybackRate').js == 1;

how to pause the player? use applescript press space? is there another way?

@starsea Like this:

use framework "AppKit"

property play : 0
property pause : 1
property togglePlayPause : 2
property stop : 3
property nextTrack: 4
property previousTrack: 5

on run
	-- Load MediaRemote classes into the ObjC runtime
	set MediaRemote to current application's NSBundle's bundleWithPath:"/System/Library/PrivateFrameworks/MediaRemote.framework/"
	MediaRemote's load()
	
	-- Run some media playback command
	my sendCommand(play)
	delay 2
	
	my sendCommand(pause)
	delay 2
	
	my sendCommand(togglePlayPause)
	delay 2
	
	my sendCommand(stop)
end run

-- Sends a media command to the local player (i.e. your computer, not an external device)
on sendCommand(theCommand)
	set MRNowPlayingController to current application's NSClassFromString("MRNowPlayingController")
	set commandOptions to current application's NSDictionary's alloc()'s init()
	set controller to MRNowPlayingController's localRouteController()
	controller's sendCommand:theCommand options:commandOptions completion:(missing value)
end sendCommand

or in JXA:

ObjC.import('Foundation');

play = 0;
pause = 1;
togglePlayPause = 2;
stop = 3;
nextTrack = 4;
previousTrack = 5;

function run() {
	// Load MediaRemote classes into the ObjC runtime
	const MediaRemote = $.NSBundle.bundleWithPath('/System/Library/PrivateFrameworks/MediaRemote.framework/');
	MediaRemote.load
	
	// Run some media playback command
	sendCommand(play);
	delay(2);
	
	sendCommand(pause);
	delay(2);
	
	sendCommand(togglePlayPause);
	delay(2);
	
	sendCommand(stop);
}

// Sends a media command to the local player (i.e. your computer, not an external device)
function sendCommand(command) {
	const MRNowPlayingController = $.NSClassFromString('MRNowPlayingController');
	const controller = MRNowPlayingController.localRouteController;
	const commandOptions = $.NSDictionary.alloc.init;
	controller.sendCommandOptionsCompletion(command, commandOptions, null);
}

To anyone stumbling upon this, looking for a solution to use the MediaRemote framework in its full capacity, I found a solution to load it on all versions of macOS, including 15.4 and above: https://github.com/ungive/mediaremote-adapter

@SKaplanOfficial thank you for the answer. Btw do you know why browsers elapsed time doesn't update?

@Pen7art Check this for why elapsed time appears as not being updated: ungive/mediaremote-adapter#6

@Pen7art @ungive If you just want the exact time elapsed, you can use $.MRNowPlayingRequest.localNowPlayingItem.metadata.calculatedPlaybackPosition.

@SKaplanOfficial - wasn't able to reproduce the command functionality on macOS 26.1. Reading media works, however writing to the media client seems to be blocked. Can anyone else confirm?

@ejbills Commands (play, pause, etc.) work for me on the 26.2 beta, tested with built-in apps, Spotify, and YouTube. I can't easily test on 26.1 at this point, but if there was a bug, it seems to be fixed.
