Use /dev/rdisk instead of /dev/disk on manual install instructions for Mac
A user is suggesting to change the manual install instructions on Mac
to use /dev/rdisk instead of /dev/disk, as /dev/disk is a buffered
version of the former.
Anybody here knows about the risks of running dd on an unbuffered
device? User says /dev/rdisk is much faster, and you can use dd on the
raw device with no problems. On an Class 4 SD card the dd command run
around 20 times faster.
I am not aware of the intrincacies of Mac’s hardware. Does it makes
sense to investigate this further, provided is not used so often?
