The most popular and stable standalone distribution at the moment is Raspbian Wheezy (Debian) Raspbian Jessie – this will give you a bit more control over installation , you can download all the software here. There are  in the main 2 methods to write an image to the SD Card – copy and paste does NOT work ! You will either need to use Terminal and command line or a GUI application such as Apple Pi Baker. You still need to format the SD card using SD Formatter, open this from the Applications Folder You should see this (Mac)

Ensure the correct SD Card is selected and Choose Quick Format unless you have an old SD Card that has been rewritten a lot.

We assume that yiou have already downloaded the image you want written to your SD Card, put it on your desktop.

Open up Terminal and type in the following commands, lets identify our SD Card first:

diskutil list

you should look for a name like this ‘disk3s1′, remember we’re looking for a whole disk not just partition.

To write the image to it we need to unmount the disk:

sudo diskutil unmount /dev/disk3s1

You should have an image on your desktop named like this ‘2012-12-16-wheezy-raspbian.img’, lets write this code in one line to the card:

sudo dd bs=1m if=~/Downloads/2012-10-28-wheezy-raspbian/
2012-12-16-wheezy-raspbian.img of=/dev/rdisk3

This might take about 15 minutes, time for another cup of tea. When .img is ready on your SD card you will se a message like this;


You can now eject your Sd card , insert into your Raspberry Pi and do 1st boot.

UPDATE; Go here for the EASY Raspbian OS install procedure.
