When I try to update, the Mac App Store tells me I have to quit iTunes AND Aperture to complete the installation. What's it doing to my Aperture??? I'm afraid Apple is going to break my favorite app now that they say it won't be supported anymore.
I'd bet that Aperture makes use of some part of iTunes, so iTunes can't be updated until Aperture lets go of it. I recently experienced a similar issue trying to update Safari while iTunes was open, probably because iTunes uses Safari's rendering engine, but I got no warning messages. Safari would just silently fail to update and reappear on the App Store updates list. After I quit iTunes, it updated without a problem.
The issue was a potentially serious one, since tracks linked with Apple Music have copy protection, and are no longer playable if a subscription to that service expires. Tracks uploaded to iTunes Match are owned by the person in question and are supposed to be freely copyable when downloaded to a device.

Just don't let your subscription expire.
