In macOS Catalina I know that under Finder -> Preferences -> Advanced I can check "Show all filename extensions" and it will do that, but I do not want that. For example, I want to keep hiding all the
However, it used to be that by default, when I saved a file from an application, the Finder would show that file's extensions. Maybe this was a setting I set that I forgot about, or maybe that was the default for the OS, I don't know for sure, but I do know that is the way it worked across all applications.
Now, under Catalina, the default is to hide the file's extension. To get the extension to show, I either need to add it to the filename when saving or save it and then go to the file's Info and uncheck "Hide extension".
Is there a way to make it the system-wide default to save new files with their extensions showing in macOS 10.15 Catalina?
