I was just about to start a similar thread, however if its ok I will ask within this one.
I understand that to use find my mac someone has to be logged into the machine. This brings me to question the "guest" account that it sets up for you.
Is there a reason that this works the way that it does. It restarts the machine and only lets you browse the web, there is no dock or anything. I have set up the guest account to act normal, as I would think that those who know about find my mac, will realise when the machine restarts the way that it does.
You can hide the guest account, if you wish. I'll have to find exactly where the setting is because I can't remember off the top of my head.
edit: Here we are;
System Preferences->Security&Privacy ->General->Check "Disable restarting to Safari when screen is locked", then next time you login, the guest account disappears. This won't disable "Find My Mac" feature.
That is not a guest account like it appears to be. What this is doing is restarting to the recovery partition and only allowing Safari to run. Not a guest account at all.
You should not disable this feature. If you do and your machine is stolen, the thief will have no way to get on the Internet so the location can be seen by you with FMM. Hopefully the thief will use this Safari only access and it will show you where the machine is.
