Hi guys, i've always wanted to solve this problem. I've started a thread before when 'Find My Mac' was first introduced to the public, but I haven't received any good advice yet. Now that more people should have upgraded to 10.7.2, any good suggestions would be appreciated. http://forums.macrumors.com/showthread.php?p=13601060#post13601060 So basically, the problem is that on my macbook air, I have 2 accounts. Account A and Account B. I also have the 'Guest (safari-only mode) enabled. When I log into Account A and Account B, I tried logging into iCloud.com to locate my mac. It works. Unfortunately, when I log into the Guest (safari-only mode) it doesn't locate anything. It just appears to be offline. But this shouldn't be the case, as according to many sources, it is suppose to be a feature where it allows thieves to connect to the internet so that the mac is located immediately because it acquires an ip address. Any suggestions would be appreciated.
