After I upgraded to the latest balenaEtcher version for mac, the writing task fails and the SD disks seem to become unusable.
I am attempting to write raspberry OS on a 16GB and 32GB Sandisk ultra disk. It failed everytime, and it wasn’t even recoverable in Disk Utility for MAC. I’ve tried to format it several times but it fails.
To make sure the problem was not on the SD cards, I ordered a brand new one, flashed it with raspberry pi manager which worked perfectly fine. After that I tried to flash the drive with balenaEtcher again, and the same happened. SD card becomes unusable.
