Hi,
With a mac you want something like:
sudo dd if=whatever.img of=/dev/rdisk# bs=1m
The m at the end might be a capital, I can't remember.
Anyways, check in Disk Utility to see the disk names for your disks.
Prepend whichever one you need with an r (for raw). That speeds up write
speeds for you.
Don't forget to do something like:
sudo diskutil umount /dev/disk2s1
to unmount the volume... You might also be able to do:
sudo diskutil umount /Volumes/whatever
to unmount the volume.
Don't use eject, since I believe this makes the disk inaccessible to the
OS... as in removes the entry in /dev.
HTH,

I don't use a Mac myself but I know that Mac is BSD under the hood so at
a terminal prompt you need to use dd.
But be very careful because if you give the wrong destination to dd you
can wipe your hard disk.
In Linux the command is:
sudo dd bs=1M if=infile.img of=/dev/sdx
Where /dev/sdx is the device name given to the card when you plug it in
to the computer either in a card slot or with a card reader.
infile.img is replaced with the name of the image you want to write.
But...you will get no better results without a USB audio dongle as
espeak will stutter. The Raspbian image on the site for download needs a
USB dongle for Orca to work.
Any USB dongle with the same chip-set as the Daffodil USB dongle will
work. Google for suitable cards that are known to work with a Pi. The
e-linux site has a list of suitable dongles and other devices.

Hi All,
Does anyone have any recommendations for changing the SD Card image?
I've not been having the best of Luck with Ubuntu Mate, not sure if it is an
audio problem as i don’t own any USB Audio device nor do I know which Audio
device is best.
So I am wanting to erase Ubuntu Mate, and install Raspbian.
I use a Mac, and I have the Pi Filler, Pi copier, and Pi finder
applications. Pi copier is not geared for this purpose.
I’d like to see if any one has any suggestion on how to go about this.
I plug it in and Mac OS says it does not notice the card. probably due to
the fact it’s formatted differently. So What would I need to do to I guess
reverse engineer it.
Would it be a Terminal prompt?
Thanks in advance.
