So, an annoying little thing about TextEdit on macOS in the later versions is that opening it up defaults to a dialog which asks you if you want to open an existing document or create a new one. I want my text editors to behave like Notepad, gEdit, etc. and just give me a freaking blank window.
To this end, all one needs to do is the following. Crack open a Terminal window and put in the following:defaults write com.apple.TextEdit NSShowAppCentricOpenPanelInsteadOfUntitledFile -bool false
Then, the next time you open TextEdit, you’ll be welcomed by a nice, blank and new document.
