> I asked if he tried `sudo chmod -x /Applications/iTunes.app`. We tried it, and I don't understand why he was so surprised that it worked, and remained a permanent solution to his issue.

Now, if you had tried to do the same with pretty much any other app that shipped with the system you would be unable to.

You're right:

   $ sudo chmod -x "Font Book.app"/
   chmod: Unable to change file mode on Font Book.app/: Operation not permitted

   $ sudo chmod -x "App Store.app"/
   chmod: Unable to change file mode on App Store.app/: Operation not permitted

   $ sudo chmod -x TextEdit.app/
   chmod: Unable to change file mode on TextEdit.app/: Operation not permitted

   $ sudo chmod -x Reminders.app/
   chmod: Unable to change file mode on Reminders.app/: Operation not permitted

Doesn't even work on iTunes as the GP suggested:

   $ sudo chmod -x iTunes.app/
   chmod: Unable to change file mode on iTunes.app/: Operation not permitted

I’m not at my computer, so I gave myself a little bit of leeway: all the other applications are certainly on the read-only system partition so I know they are not going to change at all. Certain apps like Safari and iTunes are not on that as they can be updated, so I wasn’t sure if there was anything additional for those :)

ITunes doesn't seem to actually work either.

My apologies. That may have changed with SIP. A _fully optional_ feature that is great for security, and can be turned off if its too prescriptive.

A little disappointed to see the apple hate on this thread, especially as I spent the morning fighting with debian install on a raspberry pi to just have a clean upgrade. Again, these linux issues are much less common when dealing with linux on a server, meant to run a single program, or collection of production programs. But trying to maintain an ubuntu desktop is not without work, and Windows is loaded with telemetry and ads.
