A yellow pop-up frequently appears, and Avast says, “Please allow us to protect your Mac.”
So I follow the instructions found here: https://support.avast.com/en-us/article/Mac-Security-allow-permissions
After I do Step 5 (Click Allow), nothing happens – and the Avast setup wizard never appears.
My OS is 10.13.6 High Sierra.
This seems like a bug in Avast, but does anyone have a workaround?
