Tech: Snow Leopard has teeth: Apple’s new OS has a really big bug.
- Do not log into the guest account. Since last month, users have been reporting a major Snow Leopard flaw on Apple’s support forums. Essentially, if you log into a guest account after you upgrade, then log out and go to your regular account, everything’s gone. And you can’t get it back. Yikes. This is not the kind of thing that users run into every day, but it’s a common enough feature to freak us out. source
