Selection box - solved!
Hello,
I have a problem... I suspect I turned on some kind of accessibility feature by mistake on my Mac as I was playing with the latest Mac OS release (Mojave). Basically, Mac OS is drawing a box around wherever my selection is. For example, see the system preference window, selection around the mouse preferences. See also the note window.
This is happening on my iMac 5k, but not on my MacBook Pro (both have Mojave installed)
Ring any bell as to why this is happening?
