Deleting the Music app on my MacBook Pro with Catalina 10.15.3?

That 4.63 GB is not just the app. Its whatever media you have in it. What you want to delete if you don't care for it, is the music within the App. The App itself is a few hundred MB in size.

Do note, if someone else uses that computer, you may be deleting their music.

And no, you cannot delete the App. Its a system protected App, and cannot be directly removed, nor can we assist you in bypassing the protection so it can be deleted.

I have used up almost all of my hard drive and trying to free up storage capacity. I do not use I Tunes but the Music app uses 4.63gb and I don't need it. Is there a way to get rid of this?

There is no way to remove the Music.app, this is baked into the macOS.

I can add that 4.63gb does not seem like much storage to be quibbling over...

If you need to dig deeper and free up storage:

Try something likeOmniDiskSweeper for a GUI to get a good look at itemized file size and location:

Or alternatively from the Terminal.app, more detail copy and paste the command line:

File size, and finding missing GB— list the items in the home folder with the sizes, including invisible items.

sudo du -h -d 1 ~/

File size, and finding missing GB —will list the items in root with the sizes, including invisible items.

sudo du -h -d 1 /
