Hi, I'll be happy to help with this question
is this logging on to the actual macbook itself or to a wireless network for example via the Macbook Air?
for both scenarios an incorrect password XXXXX block access but it would be possible to attempt further entries of the password
So you could use a password XXXXX program to eventually gain access?
By the way I am not asking for the name of any cracking tools. It is a case that we had several macbook airs stolen and I am trying to determine the risk factor.
well, if you have physical access then yes it's possible to gain access
easiest solution is to connect the hard drive to another system and access from there
which would get past the password XXXXX
so encryption should be used if possible
that would be the best way to safeguard data on mobile machines
let me know if you need further details too
