Hello

These is my first post in regard to Beagle Bone Black. am very new to the devices and I don’t completely understand how it work.

I accidentally delelted on the files in beaglebone , these are the files that visible through USB on my Mac Os… Now I realized, I have the most dumbest thing ever. My Mac Os wouldn’t recognized the beaglebone device and nothing is every showing up…

How can I get the beaglebone back to way I found it. because there is nothing on it now
