    Assuming you have the NAND hooked up to the computer, absolutely. You'll need to know the "file" that represents the NAND

    Well I'm in the middle of performing a hardmod on my 2015 n3ds xl. i've already built the sdcard cable device. Unfortunately, I ripped the ribbon of the lcd screen, and waiting for the spare part to come in the mail.

    But as far as using 'dd', i'm not familiar with this, so I don't even know how to start. I was going to make a VM of a windows box, and forward the usb to it so i can use win32diskwriter but if i can do it natively on a mac, i'd rather do that.

    Military base.
    In Linux terminal type:
    $sudo dd if=/dev/sdb1 of=nand.bin (for backup)
    , and
    $sudo dd if=nand.bin of=/dev/sdb1 (for restore)

    First, this isn't Linux, second you CANNOT assume that /dev/sdb1 is going to be his NAND, that might be a flash drive or some other storage media (assuming that the sdx structure works on a Mac which it seems that it doesn't)

    The principle is the same, but the naming convention is different. In any case, you are correct that the commands listed by Ninoh-FOX for Linux will absolutely not work on a Mac. Also they do not include the blocksize command which significantly increases the rate at which the data are read from/written to the NAND. Also on a Mac you have /dev/diskx and /dev/rdiskx. Using /dev/rdiskx is much faster as it provides lower-level access to the device.
