Raspbian flash to micro sd card on mac fails

raspberrypi3

#1

I have been following this guide here:

  1. I have an 8gb unlocked micro sd card inserted in a sd card adapter that’s inserted my 2015 mbp running 10.12.6.

  2. I have formatted the card using disk utility as FAT32 with masterboot record and GUID format options (tried both)

  3. I have download RASPBIAN STRETCH WITH DESKTOP AND RECOMMENDED SOFTWARE from https://www.raspberrypi.org/downloads/raspbian/

  4. I have installed Balena Etcher 1.4.8 for mac

  5. I start the flashing process by selecting the zip file, then selecting the sd card and pressing the flash button.

  6. There is very brief <500ms waiting screen that appears and the I assume the process has finished as there is no error message, nor any feedback to the user that anything has happened.

  7. This appears in the console:

I repeat the entire process with the disk image (2018-11-13-raspbian-stretch-full.img) by unzipping the raspbian download.

I am unable to proceed any further.

I check the contents of the card inside Disk Utility, and conclude that nothing has been written to the card.

What am I doing wrong? It’s a bit demoralising to be stuck so early into the process.

This is realtime:

Hi @proximity , from the log you attached I see that the elevation prompt gets a denial - do you see this when you click “flash”?
