Is disabling spell check systemwide still possible in Sierra? I wanted to comment my question directly in the thread Is it possible to disable spell check systemwide? , but I do not have enough reputation to comment, so I opened a new thread:

I just upgraded from El Capitan to Sierra and wanted to disable spell check as always for years now with this procedure:

sudo mv /System/Library/Services/AppleSpell.service/Contents/Resources \
        /System/Library/Services/AppleSpell.service/Contents/Resources.disabled
killall AppleSpell


Unfortunately this procedure doesn't work anymore as the Resources file does not exist anymore in System/Library/Services/AppleSpell.service/Contents

Does anybody know how to get rid of the spell check in Sierra?
You can disable the feature that automatically corrects misspellings but it still underlines misspelled words. Go to System Preferences, Keyboard and click on the Text tab. There is an option on the right to correct spelling automatically. Make sure this is not checked.
