Hi, I use the free version to remote into my parent's computer. Lately, on occasion, throughout the day, on my computer I get a pop-up window that says, " 'MyParent's Computer name'.local has signed in". But I know for a fact no one at their location has signed into their computer or even touched it.
It is an iMac desktop that stays powered up and logged in but these messages appear when I know for certain the computer has not been touched for hours or days and would actually be in a sleep mode.
What does this message mean and should I be concerned?
