Can you give us more information. Which Mac model and version of OS X are you using? Do you mean that you are seeing quite a bit of text when logging in rather than the usual login screen? Is the text in multiple languages?
No. Rather than an ip address in the security settings of Google. The details show my computer code, and another computer code. Also indicating two logins at the same time on different sides of the country.
will show up in security log in, even though my ip check on my computer is usual numbers for ip. If I change the password 3 times in a row, the ip address will again show up in the security settings. However, after a while, this type of thing comes back.
yes. A mac address. The first half is my computer. It is when you would see an ip address in the details of security log ins. And yes. The devices and activity is where I see log ins from my town and simultaneously another town. Same minute or even 5 minutes apart.
Could be just a glitch at Google. HOWEVER...
Change your password, NOW, just in case. You might want to set up 2-step verification too.
Mine shows my Mac at home but it also shows it in Beaumont, 16 miles away, because my ISP (Time Warner) is there.
However, I don't think that's the case here. I mean Texas and Chicago?
