Often times, when trying to deal with files on your Mac, you may want to change the file type or extension of some files, right? For the most part, changing file extensions is easy on macOS. However, macOS pops up a warning dialog every time you change the file type in the Finder, which can be annoying. If so, here is how to disable the ‘Change File Extension’ warning on Mac.
Disable Change File Extension Warning on Mac
The annoying alert dialog we’re dealing with here is there for a good reason. It helps prevent users from accidentally changing file types on their macOS device and rendering files useless. However, if you’re reading this, you know what you’re doing and this warning is only slowing you down. Here’s how to disable it.
- Click Finder from the Dock. Then click ‘Finder’ in the top menu bar and go to ‘Preferences’. Alternatively, you can press “command+comma” to open preferences.
- Click on the ‘Advanced’ tab.
- Here, disable the checkbox next to ‘Show warning before changing an extension.’
After doing that, you can close the preferences dialog. Your Mac will no longer warn you when you try to change the file extension of any file. So you can mess with and rename any number of files without ever seeing the ‘change file extension’ warning dialog.
Easily Change File Extensions on Mac
That’s all you need to do to get rid of the annoying alert box on your Mac. As I mentioned earlier, the warning has a reason, and in general, it’s best to let it stay open. However, if you’re like me and frequently change file extensions on macOS, it might be a good idea to disable the alert box to speed up your workflow.
