Note: When using macOS to interact with devices, use /dev/rdiskX (note the r) when possible (i.e., if it doesn't cause an Input/output error) as it tends to be much faster; rdisk is a "raw" character device (closer to the physical disk) while disk is a buffered block device.
If needed, mount the filesystem on macOS (read-only) and back up files before wiping the SD card.
brew cask install osxfuse
brew install ext4fuse
sudo mkdir /Volumes/rpi
sudo ext4fuse /dev/diskXsX /Volumes/rpi -o allow_other
From macOS, write Raspbian Lite to SD card. Took 5:45 for a 1.72 GB image (5.10 MB/s) when using rdisk.
