I'm operating on a Macbook Air and I have two tabs open from Acrobat Reader DC that will not close. I can't restart the computer because the tab is open and force quitting does not work.
Maybe switching off your computer?
Well if you read my initial question, it clearly says I cannot restart my computer.
What happens when you Option + Click the Reader icon in the Dock?
I didn't say restart, I said switch off. In a portable Mac, keep pressed the power button until the computer shuts down - I think.
Did you ever sove this? How?
I have the same problem
Did you try following the advice given? What happened?
