Weird estimated time

Hi everybody ,

Anytime I want to run a brute force attack with masks or a rule based attack I have really really long estimated time now I just tried another time a brute force attacks with masks and the estimated time is 40.000 years !!!
I use a Macbook Air for the moment but i'll buy a PC laptop with linux soon .

Here is the command I used : 

./hashcat -m 2500 -a 3 -1 ?l -2 ?l?u?d?s -3 ?d hash file ?2?2?2?2?2?2?2


Can you please tell me how to fix this ?


Thanks a lot
