Check out these screenshots below and then grab the download from Sébastien's website.
As you can see in my "expertly recorded" video, I'm using an old Mac Mini that was donated to me (thanks Mum!). My video shows me using unix 'scp', viewing images/PDF, listen to tunes, and playing Doom before ending with web browsing. Yes, this is as geeky as it gets. Love it!! :-)
diskutil listThis will display information to help identify the SD card - look for the capacity of your card. Mine is 8GB as you can see in the clipping, below. Thus my card is "/dev/disk1"
/dev/disk1 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: * 8.0 GB disk1
diskutil info /dev/disk1Within the output, you will see a line confirming that this is indeed our SD Card :
Device / Media Name: SD Card Reader
sudo dd if=/dev/disk1 of=~/Desktop/st-backup.img
sudo dd if=~/Desktop/st-backup.img of=/dev/disk1
