+
+If `dd`ing from OSX do the [following for speed](http://daoyuan.li/solution-dd-too-slow-on-mac-os-x/):
+
+```bash
+$ dd bs=1m if=kali-2.1.2-rpi2.img of=/dev/rdisk2
+7000+0 records in
+7000+0 records out
+7340032000 bytes transferred in 514.267776 secs (14272782 bytes/sec) # fast!
+```
+
+I had a 32GB SD card, this image transform it to a 7GB memory. To fix to the following (inspired by [this](https://linhost.info/2015/05/expand-the-root-partition-in-kali-linux-for-the-raspberry-pi/):
+
+```
+$ cd /boot
+
+$ wget https://raw.githubusercontent.com/lgierth/pimesh/master/files/raspi-expand-rootfs.sh
+
+# Check the partitions
+
+# replace $PART_START with 125001 if fdisk -l shows:
+...
+/dev/mmcblk0p2      125001 60367871 60242871 28.7G 83 Linux
+...
+
+$ chmod -x raspi-expand-rootfs.sh
+
+$ sh raspi-expand-rootfs.sh
+
+$ reboot
+```
+
+After successful reboot, run:
+
+```
+$ resize2fs /dev/mmcblk0p2
+```
