Could Mac be compromised if Gmail says this?
I had new gmail account I used only once to make account in one forum. And today I got this:
I don't have a phone I'd give out like this so no testing it. Could this be sign my Mac is infected and someone got to my Gmail account through stealing password? Or if other accounts (my main old Gmail that I checked and is working fine) are not touched, it was just google being stupid?
I'm only worried if this is bad sign for my Mac, don't really care if this gmail account is lost.
Mac mini, OS X El Capitan (10.11.6), null
