What's the best way to copy a Linux disk image on to an SD card to use in a Raspberry Pi
I tried Disk Utility but it did not allow for FAT32.
You can use
dd to write disk images to disks.
diskutil list. From the list, find your SD card from its size, partition names etc. and note down its disk number (for example,
diskutil umountDisk diskXwhere
Xis the disk number.
sudo dd if=in your terminal, drag and drop the image file to your terminal, continue typing with
Xis the disk number. At the end, the command should look like
sudo dd if=/path/to/downloaded/disk.img of=/dev/diskX bs=1m. Press Enter and execute the command. It will ask for your password. Type your password, and press enter. While you type, no letters or dots will appear, but type anyway, and press Enter.
