ITunes is the worst
Q Can I get rid of iTunes? I hate it and never use it, preferring to play my music through the Chrome MP3 player add‑on, but iTunes still starts itself when I accidentally click on an MP3 file in Finder. Every time I try dragging iTunes to the Trash it says I can’t delete it because it’s “required by OS X”. Is that true? Steve Pellier A ‘Required’ may be stretching a point slightly, but it’s certainly fairly deeply integrated. Deeply enough that even if you override Finder’s warning and delete it from Terminal with the sudo rm command, it will simply be reinstalled the next time OS X updates. It’s probably not worth fighting it on that level; there are lots of components integrated into OS X that most of us don’t use much – Chess, Photo Booth and Stickies, for example. It’s true that iTunes consumes a lot more disk space than all of those put together – around 340MB at the moment – but that’s still a fairly small chunk. Even if you only have a 128GB SSD, it’s only a quarter of a percent of your total disk space.
However, you can change which app opens when you double-click an MP3 file. Right-click one and choose Get Info, select something other than iTunes from the ‘Open with’ menu, and then click the ‘Change All…’ button to make it the new default. Unfortunately, you might need to repeat this every time you update OS X – I don’t think there’s any way around that.
If you don’t like iTunes you can change the default app for music, but not remove it completely.
