Write Image to the microSD Card in macoc with Jetson Nano

Hello, I just follow the step until step 6.

  1. Use this command to remove any existing partitions from the microSD card, ensuring MacOS will let you write to it. BE VERY CAREFUL to specify the correct disk device.
    sudo diskutil partitionDisk /dev/disk<n> 1 GPT "Free Space" "%noformat%" 100%

After entering the code, it showed

Error creating partition map: A writable disk is required (-69772)

How can I solve the problem?

Hello @kelvin913913
Can you share us the

diskutil info /dev/disk6

command’s output. Maybe your device connected as read-only.
