From the developer:
NandExtract is a tool which can extract some or all files from a nand.bin, as well as examine its contents. You can see all the blocks of the NAND dump as well as view info about the boot sector. It can be compiled on Windows, Linux or Mac OS X using Qt.
You may want to check out more software for Mac, such as QuickPerlTester, BugReporter or CoreAnimationKioskMenu, which might be similar to nandExtract.
