Its actualy pretty easy to do this in the terminal:
Code:
$ diskutil list
and it returns something like
Code:
/dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_HFS Macintosh HD 999.9 GB disk0s2 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *4.1 GB disk1 1: DOS_FAT_32 GENTOO LIVE 4.1 GB disk1s1
Now unmount the disk using diskutil replace the disk number with the id of your usb stick
Code:
$ diskutil unmountDisk /dev/disk1
And use DD to write again replace the disk number
Code:
dd if={ISO_IMAGE_HERE_} of=/dev/disk1 bs=1m
Replace if={} with the path to your iso image
