Ever since the launch of Apple's Mac OS X - the Snow Leopard operating system - in August, users have been complaining about a critical flaw that reportedly wipes out the account information of the users when they log into their "guest" accounts.

Going by the comment threads, the vulnerability causes users' data in the home folder to be erased whenever a guest account is logged into, closed and reopened. Some of the users have said that all their home folder data goes missing, with their accounts being completely reset.

Incidentally, the flaw seemingly has the most notable affect on guest accounts created and enabled before the installation of the Snow Leopard.

While users have been detailing the critical Snow Leopard flaw in several comment threads on online support discussion groups during the last two months, it is now that Apple has officially acknowledged the issue, and is working towards finding a fix to address it.

In a prepared statement, an Apple representative said on Monday: "We are aware of the issue, which occurs only in extremely rare cases, and we are working on a fix."

Though the reported data loss problem is not a widespread one, it surely is still topical enough and needs to be addressed, more so in the wake of the recent massive data loss at Microsoft's Danger subsidiary that makes Sidekick mobile phone!
