Turn spell check back on after Grammarly Desktop turned it off

Oh, thank you, Lee!

I've spent days trying to diagnose this issue. Apple support has called me three times to help diagnose, but your simple fix worked for me.

You're a legend!

Grammarly for Desktops turns off the red lines that macOS puts under mispelled words. If you uninstall Grammarly, it doesn't turn that system function back on, so now if I mispell a a word in somehting like the Mail app, there is no red line. It still seems to be spell checking, it's just not marking the words.

I have spell check turned on in System Preferences>Keyboard. I have turned it on in all apps that allow you to do so, but still no red lines.

How do I turn the red lines for mispelled words back on please?

Check spelling and grammar on Mac - Apple Support

Have you contacted Grammarly support? If they have a help Forum I would try there.

Oh, thank you, thank you, thank you.

This has been driving me nuts and I wondered if Grammarly was the cause. I so appreciate getting this solved.

This worked for me too, thank you so much for the solution!!
