I have a Mac with High Sierra (10.13.6) and I am unable to disable the spell checker.
I've tried going to System Preferences -> Keyboard -> Text and unchecking all the boxes but the spell checker still works. Every time I type "echo singlequote" (singlequote was meant to be enclosed in diamonds) the system tries to guess what I'll type next.
I have also disabled System Integrity and renamed the
/System/Library/Services/AppleSpell.service/Contents/Resources directory, but the system still tries to guess my typing every time I use quotes.
I don't have the issue on another machine with High Sierra.
I can't type without checking the screen every time I type a single or double quote, or even the ^ symbol. Having to hit the space bar every time I type a quote is driving me mad.
Does anyone know how to stop this spell checker from jumping in every time a type a quote?
