One popped up the other day saying it was from Safari on MacOS 10.9. I may have used this OS in the past, but not now. I always wipe my computers so I am curious what happened. I don't see anything like that showing up on my device list, I wonder if it is no longer supported that they can still see my files?
I have changed my password, removed other older devices, enabled TFA.
Any idea what else I can do?
