Messages for macOS, by default, check and correct spelling mistakes while you're typing. It is a handy feature, but it's a nuisance for someone who sometimes purposely wants to type in imperfect English. Even more so is for those who communicate via other English or Roman alphabet-based languages.

Autocorrect for Messages in macOS can be disabled from the toolbar menu for Messages.

Steps to disable autocorrect for Messages in macOS:

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