On a Mac, Finder hides most file extensions by default. If you happen to’d all the time prefer to see file extensions whatever the file kind, you possibly can change a easy setting in Finder Preferences. Right here’s how.
First, concentrate on Finder by clicking its icon in your dock. Subsequent, open the Finder menu on the prime of the display and choose “Preferences.”
When Finder Preferences seems, click on “Superior” within the toolbar on the prime of the window.
In Superior Finder Preferences, place a checkmark beside “Present all filename extensions.”
Shut the Finder Preferences window, and also you’re set. Subsequent, open up a Finder window and take a look at some information. You will note extensions hooked up to all of them.

If you happen to ever need to conceal file extensions in your Mac once more, revisit “Finder Preferences” > “Superior” and uncheck the “Present all filename extensions.”
Even then, some file extensions should present up. For instance, for some Mac users, some information in your “Downloads” folder would possibly present extensions anyway (That is presumably a bug.). If that’s the case, you possibly can conceal extensions one file at a time. To take action, right-click a file, choose “Get Data,” then examine the field labeled “Disguise extension” within the “Title & Extension” part. Good luck!
