How to prevent Music app from starting maximized in macos Catalina

Every time I open the Music app it starts maximized, not full screen, I can still get to the menu bar at the top of the screen. Is it possible to disable this action? If so, how. This is the only native app in macos Catalina that does this.


Thank you

So I figured it out, it took editing the com.apple.Music.plist file to fix it. Something to be careful doing.


First, I made a backup copy of com.apple.Music.plist from the ~/Library/Preferences folder. Then deleted it from there. Opened the Music app and found that the issue went away. Great except all my other settings in the app were reset to default.


Hovering over the green button it says "Full Screen" but when hovering over with the option key selected it says "Zoom". I thought maybe these are references in the .plist file.


Next I created another backup copy of the com.apple.Music.plist file. Opened it up and did some digging. I eventually found there were two keys named maximized and zoom.


<key>maximized</key>
<true/>

<key>zoomed</key>
<true/>


I found all references to these two values and deleted them. Reopened the Music app and the app opened in a normal window size.


Why the app wasn't saving the window size setting not being maximized or zoomed when closing I don't know but this did the trick for me.


Thanks

Hello and welcome to Apple Support Communities, Eric!


I understand that whenever you open the Music app it starts in full screen. I'd be happy to tell you how to avoid this.


First, open the Music app. Move the mouse over the top of the screen to show the menu bar. At the top-left, you should see red, yellow, and green buttons. Press the green button to make the app not appear on full screen. To get it to maximize, press the option key on your keyboard and then press the green button again.


If I've misunderstood your question, have a look at this article for more details on managing app windows:

I hope this helps.

Have a great day!
