Problem making image using MAC SD Clone

i just downloaded SD clone and tried making an image of an SD card from an OrangePi zero. The SD card showed up in the ‘Sources’ column of SD Clone as 8Gb with 7.8Gb occupied, but when I clicked on ‘Save image’ in the ‘destinations’ block to clone it, the resulting zip file was just 298 bytes… something tells me that the zip file doesn’t contain an image of the SD card.

That is strange. How long did it take to create the image?

Less than a second, I would say.

Can you provide a link to the image and the process you followed?
