Annoying Microsoft pop up
Recently on my iMac, at start up, I have been getting a message (top right of screen) about installing or dismissing a Microsoft update.
To the best of my knowledge, the only Windows related program on my Mac ia my genealogy software Ancestral Quest which uses Crossover to run on the Mac.
My 2 questions are:
A - Do I need to install it and
B - If not, how do I get rid of the pop up?
Thanks in advance
