I have just read couples of the last threads, where users seem got problem who look similar than mine. I am on MAC OSX mountain Lion. I use usualy JTR version 1.7.9 Jumbo who are avaible on the custom builds, = http://openwall.info/wiki/_media/john/john-1.7.9-jumbo-7-macosx-Intel-2.zip i make some tests with the Magnum build = https://github.com/magnumripper/JohnTheRipper Because i would like to update.... & Unfortunately not got the expected improvement... Look, On the version 1.7.9 ver: 1.7.9-jumbo-7_omp [macosx-x86-64] = pc2:run1 xxxx$ ./john --format=des --test Benchmarking: Traditional DES [128/128 BS SSE2-16]... (8xOMP) DONE Many salts: 15925K c/s real, 1985K c/s virtual Only one salt: 12845K c/s real, 1605K c/s virtual **************** On the last version from Magnum Github, tested today ( i just do a classic compilation without touching any file or modify any ..., i just do $ ./configure & make, all is done without any errors ) version 18.104.22.168-bleeding-jumbo [darwin12.5.0 64-bit AVX-autoconf] pc2:run xxxx$ ./john --format=descrypt --test Benchmarking: descrypt, traditional crypt(3) [DES 128/128 AVX-16]...

I try to make test with the addition of "--fork=N" option, but got an error message, seem we can not Mix " --fork=N & --test""....can you confirm this point please ? Any help with be appreciated, Thank you in advance, Regards, Donovan
