I want to burn a *.img file of Wheezy OS to my 8GB SD Card from a Mac but can't figure out how.

Any help would be appreciated. :)

is the OS you're using OSX?? – ikku Dec 27 '12 at 17:33
Yes @ikku - it is. – user4039 Dec 27 '12 at 17:39
Check out my answer here. The question is on backing up your SD card, but the process is identical, see the bit on restoring the image. Alternatively, this wiki may help. – Alex Coplan Dec 28 '12 at 15:06

There is a faq/howto available that discusses all the various OS-es. For the Mac it is (nearly) the same as under the various other types of Unix versions. The use of dd.

In short you type:

sudo dd if=path_of_your_image.img of=/dev/rdiskn bs=1m

N.B: the of=/rdev/diskn needs to be the SD card, if you do this wrong you might end up destroying your Mac system!!!! Be careful!

Be sure to use /dev/rdiskn instead of just /dev/diskn. This way you are not writing to a buffered device and it will complete much faster.

For a total step by step guide through this process please consult this explanation. There are 3 chapters for the Mac in this document.

The most easy way is described on the first chapter on Mac (Copying an image to the SD card in Mac OS X (Only with graphical interface)), it involves an application that does everything for you, to be complete I copy the link to this application here

Thanks, is there no easier way? :( – user4039 Dec 27 '12 at 17:41
It's not that difficult, and the actual copying is only one command, the rest is to make sure you will be writing to the correct device. And the first chapter states: The RPi-sd card builder utility is a app which will walk you through the process of installing to SD card. That sounds like a nice application that with a couple if clicks does what you want... The link for this app is in the document. – ikku Dec 27 '12 at 17:43
Can't get that to work. :( – user4039 Dec 27 '12 at 17:51
Oh, and the application keeps crashing. – user4039 Dec 27 '12 at 17:51
Then I guess you need to switch to option 2, Mostly GUI – ikku Dec 27 '12 at 17:54
