Why is the default action on a folder/file to RENAME it? If I press enter on a folder I want to enter it, if I press enter on a file I want to open it.
The Mac is mouse-centric. You double click to open anything , you right-click to access other operations.
If you single-click and then start using using the keyboard, it’s a fair bet that you want to rename it.
I’m pretty sure opt-enter will actually open the file if you want to open it… or cmd-O, of course
