macOS Sierra - iMessage corrects me despite spellcheck is turned off

Good day! iMessage on my mac fixes my typos as I type despite the fact that I've disabled spell check in settings.

Here is how it looks:

Is there any way to fix that? Thank you in advance.


Solution 1:

In Messages, go to Edit > Spelling and Grammar and make sure the items for automatic correction are UNchecked.
