So I’ve been out of the GPU cracking game for a while as I’ve been running a MacBook on OS X.

After doing a little digging tonight and reading up on the latest version of hashcat (v3.00) it became apparent to me that hashcat now runs on OS X platforms. At last! Thanks to @hashcat (atom) for making the software open source!

So today oclHashcat-plus-0.08 was released by atom.
