Mac OS X Snow Leopard guest account bug reportedly deletes user data

“Since Mac OS X 10.6 launched in late August, numerous reports online have detailed the issue, which is triggered by logging in and out of a guest account on a Snow Leopard machine. Upon logging back in to their regular account, users will find that it has been wiped of all data,” AppleInsider reports.

“The issue has prompted numerous threads on the Apple Support Discussions, with reports suggesting the issue cannot be reproduced with any exact certainty,” AppleInsider reports. “Apple has yet to publicly acknowledge the issue.”

AppleInsider, “A month ago, CNET detailed a potential fix for the issue, which is reportedly caused when users have had a guest account enabled for login prior to the install of Snow Leopard. The easiest way to avoid the issue is disabling the guest account.”

  1. This kind of thing is why I try to wait for a few point updates before installing a major OS upgrade. This appears to be especially true with all the under-the-hood optimizations and improvements in 10.6.

  2. This is why you back up folks. I also wonder what the ratio is of persons who do permissions repairs before they update their software. For those not familiar, always, always scan your permissions in disk utility before you update any and all software. ALWAYS!!!!!!

    You aren’t kidding! I had that exact problem with Windows 7 when I connected it to a domain. It started treating all accounts as guest accounts and deleting everything when the user logged off.

  4. why would you want to keep data on a Guest account? I would think it always did this. If you are going to keep and data on account why not use a regular account?

    I really don’t see this as a bug, but as how it should work by default. Sort of like those accounts in college computer labs. You save nothing on the machine and its wiped clean once restarted.
