How to disable autocorrect for Message in macOS

Message for macOS automatically check and correct spelling mistakes while you're typing. This is a handy feature but for someone like me who don't always type in perfect English on purpose, it's more of a nuisance. Even more so is for those who communicate via other English or Roman alphabet-based languages.

Autocorrect for Message in macOS can be disabled from Finder's configuration menu.

1. Click on Edit at the Message menu.
2. Click on Spelling and Grammar option.
3. Click on Correct Spelling Automatically to remove the tick mark.
