Concerns are beginning to grow about reports of a bug in the Snow Leopard Operating System for Macs that could see users lose all their data.
Apparently, when users log into their machines as a guest, they can find their data has irretrievably gone when they log back into their proper accounts.
This is obviously a major problem, although Apple has yet to respond either to its customers or through its usual mechanisms.
The suggestion at the moment is that users disable the guest account, just to be on the safe side.
TechRadar will, of course, keep an eye on the situation and bring any further information that we can gather.
