How to Deauthorize Computers on Apple Music?

This is a good reminder that there is a difference between authorization and association. And yes, it describes that you can deauthorize all devices, but only if the "Deauthorize All" button is displayed—which it is not for me. I'm guessing it is not shown because Music is saying there is only 1 authorized computer. However, as mentioned, Music is also saying that I have authorized 5 out of my available 5.

So there's no way to Deauthorize All, and there's no way to find out what other 4 computers are authorized.

Right…as I mentioned, right where you indicated it says "One machine is authorized to play content purchased with this account," and there is no button for "Deauthorize All" in order to reset everything.

Yes, I did try de-authorizing and re-authorizing my current laptop, and I get the response, "Including this one, you have authorized 5 computers out of your available 5."

I did actually solve the issue using an approach similar to what you suggested. I have an older Mac desktop that I don't use much anymore, which has an older operating system that still uses iTunes instead of Apple Music. So I loaded that up, checked my account settings, and it did show that 5 computers are authorized, along with the De-authorize All button next to it. So I de-authorized all, then re-authorized the old desktop. It said 1 computer out of my available 5 are authorized.

Then I went back to my new laptop and re-authorized it. Finally, it now declared that I have 2 computers out of my available 5 authorized, which is now correct.

I don't know why the old iTunes app displayed things correctly and allowed me to de-authorize all and the Apple Music app would not, but at least the problem is solved. Not sure that will help anyone else with a similar problem, though...

Thanks, Tal. That only shows which devices are "registered" or "associated" with an AppleID, not which computers are authorized for Apple Music (see first response above).

Good thought, but I haven’t used the Deauthorize All command before, and I’m definitely looking where they’re telling me to. Guess I’ll have to reach out to Apple.
