Bonjour is a utility program that is integrated into some Apple programs. It is usually used by iTunes to find shared music libraries. Safari also uses Bonjour to find devices advertising web pages on your network. Bonjour is not a program you use directly; you won't see a "Bonjour" icon on your computer desktop. It works silently in the background, automating various low-level network tasks.

It is usually installed automatically when you install iTunes and it runs a process that starts up and runs in the background when you start your system. All of this is done in the background and, a lot of the time, you don’t really know that it’s there.

Can I Uninstall Bonjour and Still Use iTunes Normally?

Uninstalling the Bonjour service without doing any harm to the computer. But, uninstalling or disabling the Bonjour service may limit the functionality of iTunes. If you ordinarily use any of the services provided by Bonjour, then the apps through which you use those features need Bonjour to work. Removing Bonjour from your device will cause those apps to stop working properly.

But if you don’t do anything of Home Sharing, remote app or syncing to Apple TVs, you can uninstall bonjour. iTunes will remind you once next time you open it. It will work fine.

Besides, you can also uninstall Apple Software Update if you don’t want that running. But don’t uninstall Apple Application Support because they are absolutely needed for iTunes to function.
