Apple admits to Snow Leopard bug

14 10 2009

Some users of Snow Leopard, Apple’s newest operating system, are losing huge amounts of data when logging in to their computers under a guest account.

More than 100 users have reported the problem on Apple‘s support forums. Many complain that their entire user profile, including favourite websites, pictures, videos, documents and other crucial files, have been lost.

The bug appears to affect users who already had a guest account enabled before upgrading to Snow Leopard, which was released in August. It appears that a glitch within the software tricks the computer in to treating the user’s main account as a guest account, and resets the profile every time the user logs out. Some users who logged in to a guest account then switched to their personal profile have found their personal data has been wiped.

Users who have backed up their data to an external drive or Apple Time Machine can usually restore their files, but other people who have not recently backed up are finding it almost impossible to restore data to their machine.

Apple said that the problem occurred “only in extremely rare cases”, and that it was working on a software update to correct the problem. It advised Snow Leopard users to delete any previous guest accounts, carried over to Snow Leopard during the upgrade process, and instead create a new guest account, directly through Snow Leopard, so that it was native to the operating system
