Guest Account getting turned on but how?

Yes, I DO have "find my mac" turned on. That, in fact, is the only part of iCloud I currently choose to use so I uncheck all the other iCloud offerings but I DO have "find my mac" enabled. I was going to mention that, in fact, when I wrote the first post as I wondered if having iCloud turned on is somehow causing this to happen. But, curiously, I have another MacBook Pro (late 2013) that is remarkably similar to this new computer but 4 years older, and no Touch Bar of course. It also has "find my mac" turned on but the Guest user is off and stays off. But I have been having some other issues with this new computer automatically connecting to my older macbook pro and that has prompted me to guess that it's somehow an iCloud issue so I have had occasion to turn iCloud off and then back on (for "find my mac" only) a few times in the recent days. I have not paid enough attention yet to see if each time I turn iCloud say back on that it's also enabling the Guest account at that time??? But my, if it is, I would think that's pretty scary from a security point of view. But maybe you've hit upon something. I will next do a few tests where I turn iCloud off and then back on, followed by checking to see if the Guest account would then get turned back on.

But are you saying you think it's normal behavior to have the Guest account turn on when you enable iCloud???

thanks... bob

I see. I just went over and read the link you posted. Thanks. That does make sense, that hopefully a bad guy who might steal my mac would hopefully not know my password and if the only way to locate ("find my mac") is to have it on the internet, it would make that "finding" possible only if a guest account with no password required was on there so the bad guy would light it up on the internet. Makes some sense.

I've noticed recently with a new car we just bought that is got nav and all that any time I take it out some place and park it, I get a text message as I walk away from the car telling me where the car is located. But it doesn't do that when I take it home and get out of the vehicle, as if maybe somehow they figured out it was silly enough to tell me where my car is when I'm out in the world with it but that it might irritate me if it told me each time I took in home. And that it would. Maybe we are getting just a tad TOOOOO connected...

thanks for the help and the link.
