But, that guide does have one problem. The way they tell you to use the
dd tool results in a very
Here’s what happened when I followed the instructions to install Raspbian on a cheap SD 16 GB SD card.

Luckily there’s another way! OS X provides
r stands for raw and provides a
more direct interface with the SD card. In this case, more direct = more faster.
The same copy took just over 10 minutes. Not too shabby.
Some Stack Overflow answers indicated that using bigger chunks might speed things up even more. I gave it a try.
The result is almost exactly the same. It seems that block size does not matter too much.
A tip about
dd is a neat tool, it’s hardly verbose. Sometimes it’s hard to tell if it’s working hard, or if
the process is hung (which can happen if your computer goes to sleep).
You can query it for a status update by pressing
