iMac is making a box (covers the width of the screen) with large font on selected or typed text. Very annoying!
I was in a word document and suddenly everything I typed was repeated in a large box with large characters. I left word and found the same thing on my desktop, using MacOS Big Sur 11.7.10. I've tried rebooting, doesn't help. Everything I type or select on screen results is a box covering the width of the screen. Can't find anything on Google. Anyone here see this? How to fix it?? Very annoying!
Thanks
