Help with partial known simple OS X password

[dasgeek]

I tried the changes to my command and got error Hash '-': Line-length exception  No Hashes Loaded.

Code:

./hashcat -m 7100 -a 3 - o cracked.txt hash.txt -1 xyz?d?d?d?d

I know this means either my mode is wrong or my hash is bad.

Is 7100 correct for OSX 10.10 password? It is listed Salted-SHA512-PBKDF2 in the ShadowHashData.

My hash looks correct for the 7100 mode in the table of Generic hash types. My entropy hash is longer than the example. Should it be the same length?
