Making SD image with Mac?

Mon Jul 09, 2012 9:39 pm

1. DL'd the Debian squeeze image, unzipped, checked the SHA1 was correct.

2. Used 'dd' to make the image to the SD card:
dd if=debian6-19-04-2012.img of=/dev/disk5s2

That took over half an hour.
Note: the disk would not mount to the Mac (OS X 10.7) after the write was finished.
Reported as
3808593+1 records in
3808593+1 records out
1950000000 bytes transferred in 2296.802111 secs (849007 bytes/sec)

3 Set it all up
- iPhone 5W power supply with USB cable
- HDMI to television
- Apple keyboard and mouse

4. Powered it up.
Power light "ON"
OK light is a pinpoint, not bright like the power light.
Nothing on screen (verified I had the right HDMI selected/checked others).
Other LED's are off.

So, I believe I didn't get the image onto the SD card correctly. What's the best way to do that with a Mac? (OS X 10.7).

Thanks.

The procedure HERE worked for me.

your /dev/disk5s2 would of sent the whole lot to partition on the SD card whereas you need /dev/disk5 so that it uses the whole card.

I've used disk5 as an example - you need to be clear what diskX you are using so you don't overwrite something you'd rather keep.

And yes, it takes a while, 30 minutes is not unusual.

On Mac OS X it would actually have been rdisk5. Also he missed the bs=1m switch in the dd command.

If you still have issues (took me a couple of tries to get it working) I wrote my attempts up here http://jonmacey.blogspot.co.uk/2012/06/ ... c-osx.html
