Hashcat cannot find my own password (password kwown) on TrueCrypt 7.1a file volume

[Buffarnaud]

Finally

I found the solution.

Running on a Mac consists to use GPU though intel (worst than Nvidia or others)

And Hashcat select the GPU before CPU

I tried to force to use CPU with the -d parameter, didn't work

But the right parameter is : -D (and the device number)

My last command which cracked the password :
./hashcat -D 1 -a 3 -m 6211 easy.tc easy?d?d?d?d

Used the CPU, and found "easy1234"

Now I continue with my others files ^^
