OSX 10.10 hash

[roggerx]

I'm currently looking into experimenting with mask attack.  I'm reading the wiki right now and have a few questions .

Would the command 

Code:

command: -a 3 -1 ?l?d ?1?1?1?1?1

be used for searching for a password that would contain only lowercase letter and numbers?

Another question I have is does hashcat run until it finds the password or until it's finished running through all possible options?
