Flashing Raspberry Pi on Mac
I just got a Raspberry Pi 2 for me and my daughter to hack around on.
Part of the process in setting up a Pi is that you need to flash a SD with one of a number of custom linux images. I was following the official flashing instructions and I was having real problems with the speed. I let the device format for about an hour before I just gave up.
Searching around yielded very little help. Most answers were something along the lines of “Your SD card reader is probably broken”. However, I finally discovered the culprit.
Apparently on OS X the
disk2s1 name is actually some sort of pointer or symlink to actual name of the drive. The work around is pretty straight forward:
rdiskn is the actual name of the disk which
diskn points to. I’m honestly not sure why this causes such a speed decrease (and it’s definitely worth looking into). Also if anyone knows how to submit a patch to the Raspberry Pi docs please let me know.
