What is the proper way to delete sd cards ? I have always heard to not delete them using your computer but to wait until you go back to your camera and delete the card using your camera. I have a 2017 MacBook Pro. is there any way to delete the sd cards using the computer without corrupting the card for future use ?

For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
Romans 1:20
