As noted by Gotschi you can't mount an ext4 partition on the Mac, but you can backup the SD. The following is a script I use. This uses diskutil to find a disk with a Linux partition to automatically find the SD card. ![]() NOTE This takes quite a while to copy! #!/bin/bash # script to backup Pi SD card #DSK='disk4' export DSK=`diskutil list| grep 'Linux'| cut -c 69-73` if [ $DSK ]; then echo $DSK else echo 'Disk not found' exit fi diskutil unmountDisk /dev/$DSK echo pleae wait! Sudo dd of=~/temp/Pi/Piback.img if=/dev/$DSK bs=2m echo backup completed - now compressing gzip -9 ~/temp/Pi/Piback.img #rename to current date mv ~/temp/Pi/Piback.img.gz '~/temp/Pi/Piback`date +%Y%m%d`.img.gz'. Unfortunately, you can only mount the ext3 (disk1s3 & disk1s6) partitions with 3rd party programs (maybe some FUSE module). I tested mounting the SD card in a VM, but the SD card reader seems not to use a USB connection internally, instead it is directly connected to another BUS. (I only tried VMware Fusion, maybe parallells gives you better options) you can either backup the whole SD card (results in a 16gb file): sudo dd if=/dev/disk1 of=~/Desktop/SD.img bs=1m or a certain partition: sudo dd if=/dev/disk1sX of=~/Desktop/SD.img bs=1m where X is your partition number if it gives you a Device busy error, be sure to 'deactivate' all partitions on the SD card in the Disk Utility. When you format a disk, the file system you choose essentially governs which devices can read or write to the disk. What is the best USB 3.0 hub for Mac?

Sometimes it is a good idea to get a fresh start with an originally blank microSD / SD card, assuming no valuable charts or singularly irreplaceable data is stored on the card. You may do this by resetting the file system on the card which removes all existing files. Computers with Windows and Mac OS X have built-in utilities to format microSD or SD (or other media type) cards. These may be adequate for your use and there are some web sites you can find with searches such as 'How to format SD card on Windows' which will explain the method. An alternative is to use a free simple app provided by the SD Card manufacturer's organization. Download and install the Windows or Mac app at the bottom of this web page: The web site also posts nice simple PDF 'how to' documents on using their formatter utilities. ![]() Follow the instructions in those documents. Generally, you will want to do a full and thorough reformat of an SD card, not the 'Quick Format' option. The SD card format chosen should (preferably) be simply ' FAT' (file allocation table, 16 bit); otherwise accept FAT32. So far, in our Fugawi related purposes, we have had no use for the exFAT file format system. Formatting as FAT provides the greatest range of compatibility (disregarding efficiency / optimization), at least for cards with a capacity 32 GB or less. If you really must use a built-in Windows method, right-click the correct drive letter representing the microSD or SD card and select Format. Select FAT or FAT32 from the drop-down menu (never choose NTFS, or Mac OS Extended). Enter an arbitrary name for the card, and un-check / de-select the Quick Format option so a full format is done instead.
