How to permanently turn off check spelling while typing in macOS! How to permanently turn off check spelling while typing in macOS - for each and every app. Whenever I turn off this option in anyone of my default or third party mac apps within a few seconds these option turns itself on automatically, so is there any option to turn this off permanently across each and every app? 

I have already tried each and every solutions mentioned in these question Can&#39;t disable &#39;Check spelling while typing&#39; in &#39;Notes&#39; in OSX El Capitan 10.11.6

But still it automatically gets turned on!
Go to system preferences, keyboard. Click on text tab and there is an option on that window to correct spelling automatically. Uncheck that box.
