Help with partial known simple OS X password

[dasgeek]

I normally would not ask a simple question, but I have lost a family member and am trying to crack their user password on their Mac. I have read alot about Hashcat options and brute-force character sets.

I know it is probably a short password (8 characters) and I know the first three letters. I will be running Hashcat on a Windows setup. I have the hash all set to go. I am just wanting to make sure I write the command correctly. Can someone help me get the command correct?
