Bug Description

On the Page:

https://developer.ubuntu.com/core/get-started/installation-medias

Section: On Mac OS > Step 8. (You can now copy the image to the SD card, using the following command:)

There is an issue with the command line instruction:

sudo dd if=~/Downloads/<image file> of=<drive address> bs=32MB

Issuing the above command results in error: "dd: bs: illegal numeric value"

The command should be corrected to:

sudo dd if=~/Downloads/<image file> of=<drive address> bs=32M

Above fix has still an issue with option bs=32M and still getting the error: "dd: bs: illegal numeric value"

it should be bs=32m [lowercase 'm'] and it works for me.

The same issue is for Ubuntu, step 5, and it's not yet fixed neither for Mac OS nor for Ubuntu.
BTW, on Debian the ‘M’ should be uppercase.

Thanks for the update, there is indeed a discrepancy in unit parsing between Linux VS Mac, after some testing, this has been addressed in https://github.com/canonical-websites/developer.ubuntu.com/pull/311 and will be deployed later today
