I’ve had my pi for a few months now, and it was working fine, but I decided to remove OSMC from it and replace it with Raspbian. After having erased OSMC, I decided against it anyways so I wanted to reinstall, but while doing so, my SD card unmounted itself during the install and caused the install to fail. Afterwards, the SD wasn’t readable and I had to reformat it. I’ve gone through this process multiple times now, and eventually figured the SD was corrupt… So I ordered a brand new SD from a different brand, except that its doing the exact same thing during the install.
In the mean time, I’ve tried rebooting my macbook using the PRAM method, installing an earlier version instead of the latest… I’m at loss here. I’ve enclosed the installer log below, it’ll expire after a week but I’m happy to reupload it any time.
TL;DR - Micro SD keeps unmounting during OSMC install for RPI 3 using Macbook Pro Retina, OS Sierra
