Ive looked around the forum and havent found an exact match. I have a large grey box just hanging out and wont go away. I dont have any sort of footnote or header set up as far as i can tell but this popped up and i cannot undo it and cannot recreate whatever it is i did to make it pop up in the first place. Um, help?
Unfortunately it doesnt appear that i can upload a screenshot of it. But its a large grey box that almost looks like a thought bubble as it has a little down arrow centered in the bottom part of the box.
Hmm. That looks like the Mac OS Dictionary/Thesaurus box. By default, a three-finger tap on the trackpad will bring it up, and another three-finger tap should make it go away.
The setting comes from the Apple → System Settings → Trackpad → Look up & data detectors option.
Ah hah! I would not have thought to look at this. Thank you! So, i turned off that setting in system settings → trackpad. The box did not go away. But, the old reboot + having that option unchecked fixed it!
Thank you - this is my first Mac after decades and decades of windows so i am still very much learning it.
