I'd like to create an Ubuntu live USB stick on a Mac to use to install Ubuntu on another machine. How do I accomplish this?
Taken from here:
We would encourage Mac users to download Ubuntu Desktop Edition by burning a CD. But if you prefer to use a USB stick, please follow the instructions below.
Note: this procedure requires that you create an .img file from the .iso file you download. It will also change the filesystem that is on the USB stick to make it bootable, so backup all data before continuing.
Tip: Drag and drop a file from Finder to Terminal to 'paste' the full path without risking typing errors.
Open the Terminal (in
/Applications/Utilities/or query Terminal in Spotlight)
Convert the .iso file to .img using the convert option of hdiutil. Example:
hdiutil convert -format UDRW ~/path/to/target.iso -o ~/path/to/ubuntu.img
Note: OS X tends to put the .dmg ending on the output file automatically.
diskutil listto get the current list of devices
Insert your flash media
diskutil listagain and determine the device node assigned to your flash media
diskutil unmountDisk /dev/diskN
Nwith the disk number from the last command; in the previous example,
Nwould be 2)
Execute the following command while replacing
/path/to/downloaded.imgwith the path where the image file is located; for example,
sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m
/dev/diskmay be faster.
- If you see the error
dd: Invalid number '1m', you are using GNU
dd. Use the same command but replace
- If you see the error
dd:/devdiskN: Resource busy, make sure the disk is not in use. Start the Disk Utility.app and unmount (don't eject) the drive.
diskutil eject /dev/diskNand remove your flash media when the command completes
- Restart your Mac and press Alt while the Mac is restarting to choose the USB-Stick
You can do it really easily with unetbootin which is available for Mac OS - the upside being it doesn't need more than a few clicks on a simple GUI.
(note this is only for newer Intel Mac's, and won't work with older PowerPC machines unfortunately.)
You could try following the instructions on ubuntu.com.
Additionally, you could try looking at some of these links for help:
Insert your USB drive.
Make UNetbootin executable from file properties.
Now click in Diskimage. Give the path of downloaded ubuntu iso.
Then select your pen drive from list. Then press ok. Wait until finish. After that you are able to boot or install Ubuntu from that pen-drive.
You can use the Linux USB Creator. The Linux USB Creator for Mac has been released. This is the easiest way to create a live linux USB on a mac.

The other option is to use UNetbootin.
If your Mac is a G4 or G5 take a look at this.
