How do I copy the firmware file to my SD card using a Mac?
Right click (or CMD & click if using a Mac) on the bin file in your downloads folder and select 'Copy', then click on your SD card as it appears in Finder to view its contents, right click in the white space, and select 'Paste' to copy the file to the SD card.
