full parallel power of device

[Benoit]

Good Morning,
hashcat has been running a script for more than 10 hours on my daughter's MacBook Air
the script is : 
./hashcat -d 2 hash.txt -m 14800 -a 3 rockyou.txt

As I am monitoring the status, I have continuously the following message:

• The wordlist or mask that you are using is too small.This means that hashcat cannot use the full parallel power of your device(s).Unless you supply more work, your cracking speed will drop.For tips on supplying more work, see: https://hashcat.net/faq/morework

• Approaching final keyspace - workload adjusted. 

I went to the far/morework to see if I could use the full parallel power of the device but I am not sure what to do. 

Any help, please?
Thanks in advance
