# MacOS – How to stop Mac to convert typing double dash to emdash

macos

I think it's a Mountain Lion thing, when you type – (dash) twice, it becomes — (emdash). When you type tm, it becomes ™ (trademark symbol). Or when you type three . (dot), it becomes … (elipsis). Some are useful, some are very annoying. Overall, I want to stop that. How can I achieve this?

If you want to stop -- from being turned into — (emdash) you need to use the + button and add a new rule to replace -- with -- (replace with itself)
