disable private browsing on my MacBook Pro.

Hi!

There is no way to disable it per say, you just wouldn't use it. Private browsing isn't the default, it's something you manually click on.

Here's a link to learn more about Private browsing on a Mac: Browse in private in Safari on Mac - Apple Support

Hope this helps,

You might want to install a different browser, one that doesn't have private browsing. You can then disable Safari.

That's pretty tricky. You would have to disable VPN as well as the ability to install apps using their Mac user ID. And, of course, they would have to have a separate username on the Mac that did not have Administrator rights.
