trouble with brute-force

[namiman]

I'm new to hashcat, and I can't seem to get the syntax right.

I have a file "hash" with the content "a94a8fe5ccb19ba61c4c0873d391e987982fbbd3" <- sha1 of "test"
and a file "pass" with the content of "test"

If I run "hashcat -m 100 -a 0 hash pass", it succeeds, Status.........: Cracked

But when I try to brute-force it with "hashcat -m 100 -a 3 hash ?l?l?l?l"
it comes back with Status.........: Exhausted

Any suggestions?

OS X 10.11

So weird. I tried again, this time with 3.0.0, but its still the same. Success on the dictionary, and failure on the bruteforce.

works here on 2.0(cpu) and 3.1 (opencl nvidia)

Looks like someone else had the same problem and it may be an issue with OSX and nvidia, although I feel like ALL methods of cracking would fail in that case, rather than one working and another one not.
