A significant bug in Mac OS X 10.6 Snow Leopard could affect you, if you have upgraded from Mac OS X Leopard to Mac OS X Snow Leopard with guest account enabled. This bug, although difficult to reproduce, could result into irretrievable loss of user account after using the guest account. When this problem occurs, you need to restore data from backup. In case if backup is not available, go for Mac Data Recovery solutions using appropriate tools.

Mac OS X Snow Leopard has a problem with how the guest accounts are tackled on systems, which have guest account enabled before upgrading from Mac OS X 10.5 Leopard.  If you have accidentally logged into your guest account and upon logging out and back into your normal accounts have found your data missing.

After you upgrade to Mac OS X 10.6 Snow Leopard, some issues with the account configuration could result into clearance or damage to the existing user accounts. All the accounts are reset when you reset the guest account. It causes critical data loss and require Data Recovery Mac to be sorted out.

It has been observed that this problem has not occurred so far to the system that has guest account enabled after upgrading to Snow Leopard. As such, this is a preventative step to disable the log in ability of guest account and re-create the account so the Snow Leopard could set up instead of keeping the account configuration that Leopard set up.

Furthermore, if you don't need guest account, you can just disable it. For handling lost home folder issue, you would need to have complete backup of your data. Immediately restore your system from current backup. Unavailability of backup cause critical problems and require recovery through commercial tools.
