If you are comfortable with the command line, you can write the image to an SD card without any additional software. Open a terminal, then run:
diskutil list
Identify the disk (not the partition) of your SD card, e.g. disk4, not disk4s1.
Unmount your SD card by using the disk identifier, to prepare it for copying data:
diskutil unmountDisk /dev/disk<disk# from diskutil>
where disk is your BSD name e.g. diskutil unmountDisk /dev/disk4
Copy the data to your SD card:
sudo dd bs=1m if=image.img of=/dev/rdisk<disk# from diskutil> conv=sync
where disk is your BSD name e.g. sudo dd bs=1m if=2017-09-07-raspbian-stretch.img of=/dev/rdisk4 conv=sync
This may result in a dd: invalid number '1m' error if you have GNU coreutils installed. In that case, you need to use a block size of 1M in the bs= section, as follows:
sudo dd bs=1M if=image.img of=/dev/rdisk<disk# from diskutil> conv=sync
This will take a few minutes, depending on the image file size. You can check the progress by sending a SIGINFO signal (press Ctrl+T).
If this command still fails, try using disk instead of rdisk, for example:
