Disable confirmation dialog when changing File Extension in macOS Finder

Question

Every time I change a file type in Finder, I'm forced to confirm that I actually want to change the file extension.

Are you sure you want to change the extension from ".old" to ".new"?

If you make this change, your document may open in a different application.

Keep .old Use .new

How can I stop going through this confirmation step?

Answer 1

Finder > Preferences > Advanced

Show warning before changing an extension

Uncheck this option to disable the warning confirmation dialog when changing or renaming a file extension in the macOS Finder.
