How to Disable the “Change File Extension” Warning on a Mac

If you do a great deal of file shuffling on your Mac, you might get irritated at the “Are you absolutely sure you want to modify the extension?” warning that normally pops up when you consider to rename a file’s extension in Finder. Fortunately, this warning is quick to disable. Here’s how.

To start with, click on the Finder icon in your Dock to bring it to the foreground.

In the menu bar at the major of your screen, click on “Finder.” In the menu that seems, pick “Preferences.” (Or you can push Command+Comma on your keyboard.)

In “Finder Preferences,” click the “Advanced” button in the toolbar.

In the “Advanced” Finder Tastes segment, uncheck “Show warning before altering an extension.”

It is that straightforward. Close the Finder Tastes window, and the following time you modify a file extension in Finder, you will no lengthier see a warning. Speedy rapidly!

By the way, if you generally want to see file extensions on the Mac, just revisit “Finder Preferences” > “Advanced” and test “Show all filename extensions.” You are going to be slinging data files like a pro in no time.
