Learn to dual-boot a Mac using a second operating system running Linux and use it to troubleshoot hardware problems by unbricking a Micro SD card.
Recently, while creating a physical back-up of my Mac, I ended up corrupting the Micro SD card I was using to perform the back-up operation. This translated into a one line cautionary alert inside the related blog post:
Turns out removing an SD card during a 100+ GB 77,000 file transfer from a Mac to an SD card isn’t the best idea – despite what a five year-old might tell you.
After several hours of toiling with Disk Utility, diskutil and dd on macOS the furthest I got was to experience the same issues as another individual who posted on Apple Exchange 3 years ago - their question unresolved, until now.
