Devastating But Rare Snow Leopard Guest Bug

Apple recently acknowledged that in certain cases, users running Snow Leopard find that some of their files have been accidentally deleted by the system after they had logged in and out of their "Guest" user accounts.

How could something like that possibly happen? Well, the Guest account deletes any files created in your guest's home folder so that you don't have to clean up after your friends. Snow Leopard reorganized a lot of system folders under the hood of OS X, and there is probably some mix up that can occur in certain cases that causes the Guest account clean-up activity to mistakenly delete content in another user's home folder.

If you don't need the Guest account, it might be wise to disable it until Apple sends an update through that fixes the bug. But if you're like me and use undercover recovery software that requires something like the Guest account to be enabled, you might try the following.

According to prominent Mac security software manufacturer "Intego", the solution to the Snow Leopard Guest account bug may be in disabling the Guest account, and then re-enabling it. That's my plan, and I recommend a restart in between.

[UPDATE: Apple recently released an OS update that, among other things, claims to fix this bug.]
