Verify the integrity of a flash/SD card on a Mac using F3 and F3X

TL;DR I just want an App for that but I'm cheap and don't want to pay - go here

Command Line Testing your SD card using F3 on Mac OS X

You love the command line and want to test your SD card? 

The software “F3” (either meaning “Fight Flash Fraud” or “Fight Fake Flash” according to its author Michel Machado) is an open-source implementation of the same algorithm h2testw employs to determine the integrity of a memory card (or any volume you mount on your Mac for that matter).

Vigil++ Because eternal moral vigilance is no laughing matter.

It's Vigil for C++ but with the chance of redemption!

Bob Nystrom has created the excellent Vigil programming language that auto-deletes any deviant code from the code base! Vigil++ is a denomination that offers redemption! Whilst it does deliver implore and swear macros, it does not adhere to the extreme run time vigilance of Vigil by deleting code but rather throws a moral-exception and a frowny face ಠ_ಠ as appropriate admonishment! But whilst you will be chastened, you will also be given the chance of redemption by being able to recover from the moral-exception.

Why Vigil++?
