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.
Note: this procedure requires that you create an .img file from the .iso file you download.
Tip: Drag and drop a file from Finder to Terminal to 'paste' the full path without risking typing errors.
- 1
-
2
Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight).
-
3
Convert the .iso file to .img using the convert option of hdiutil (e.g.,hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)
Note: OS X tends to put the .dmg ending on the output file automatically.
-
4
Run diskutil list to get the current list of devices.
-
5
Insert your flash media.
-
6
Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2).
-
7
Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2).
-
8
Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.imgor ./ubuntu.dmg).
- Using /dev/rdisk instead of /dev/disk may be faster
- If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M
- If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk Utility.app' and unmount (don't eject) the drive
-
9
Run diskutil eject /dev/diskN and remove your flash media when the command completes.
-
10
Restart your Mac and press alt/option key while the Mac is restarting to choose the USB stick.
