    How to create a RAW image (.IMG) of the SD card on Mac?
    « on: May 28, 2019, 09:36:12 AM »
    Hi everyone,

    Do anybody know how to create a complete sector-by-sector image of the SD card on Mac?
    I need the image file to include data from free space blocks of the card. This must be similar to .img type of images on Windows (don't confuse this with the legacy .img type on Mac, which is a different thing).

    Thanks!

      One way is to use the dd command, from the macOS terminal (Applications -> Utilities -> Terminal).

      Computer Hope has documentation for the dd command, but for Linux. macOS reference is here:

      https://ss64.com/osx/dd.html

      For examples of using dd with a mounted SD card, you might want to review this information:

      I hope this helps.
