Bootable USB Installers for OS X Mavericks, Yosemite, El Capitan, and Sierra. First, review this introductory article: Create a bootable installer for macOS. Second, see this How To outline for creating a bootable El Capitan installer. Simply replace the Terminal command with the one from the preceding article by copying it into the Terminal window.

Creating disk image files allows you to preserve discs, drives, applications and large folders in their entirety for transport, sharing and future use. While you may have used your Apple computer's inset Disk Utility to burn a DMG file to your computer in the past, you may not have known that you can write the disk image directly to a USB storage drive.
Copy all of the files you wish to burn to the DMG into a single folder or volume if you have not already done so.
Launch Disk Utility from the Applications folder.
Dmg To Usb Mac App
Select the disk or volume from which you intend to burn the DMG from the list in the left pane.
Select 'New' from the File menu.
Choose 'Disk Image from Folder' or 'Disk Image from disk name' if you want to burn a DMG of a directory or drive, respectively.
Name the DMG file in the appropriate field.
Select the connected USB drive from the file destination browser.
Select the DMG format from the ensuing pop-up menu. Choose from compressed, read only, read/write and DVD/CD master.
Click 'Save.'
Tips
Add password encryption to your DMG if desired. Select 'AES-128 (recommended)' from the encryption pop-up in the Image Format dialog.

This guide covers the verbatim copying of a DMG image to a USB thumb drive using only Linux (no need to find a Mac). If the DMG was intended to be bootable then the resulting USB will be bootable.
Convert to ISO
Linux doesn’t much care for DMG files. Sure, it’ll play nice with them. But we don’t just want to play nice. We want to copy a DMG image to a USB drive and keep it as verbatim as computationally possible. In order to do this, we’re first going to convert the image to a format that’s a little more universal: ISO.
We’re going to use dmg2img to convert the DMG to an ISO image. If you already have dmg2img, great. If not, install it using your distribution’s native package management system.
On Ubuntu, you’d do it like this:
Once you have dmg2img installed, begin converting the DMG file:
After a few minutes, you should have a second file called image.img. This file can be used like an ISO. All we have to do is change the extension. Use mv to do this:
Make sure you specified “image.img” and not “image.dmg”! Diskwarrior 5 manual. Working with three different file extensions can get kind of confusing.
Poe phys dmg rolls. Ok, so we should now have a file called “image.iso” which is just “image.img” with a different extension.
Dmg To Usb Mac Terminal
Now we want to write “image.iso” to our USB drive. I used “lsblk” to figure out how the system was identifying my drive. The lsblk command lists all disks connected to the system. It’s usually pretty easy to figure out which disk is which based on their size. Just be sure you’re sure. This process is going to overwrite the target disk with the contents of our DMG image file. Any preexisting files on the target disk will be lost. As usual, make sure you have a proper backup.
Make sure the target drive isn’t mounted. Unmount the drive with your distribution’s GUI.
Or you could just unmount it from the terminal:
Most systems seem to mount external drives in /media. Sometimes the drive might be mounted in /mnt or elsewhere.
Write the ISO image to the USB drive like this:
Replace “X” with the appropriate letter. For example “/dev/sdb”. Be sure to use the drive directly and not a partition within the drive. For example, don’t use “/dev/sdb1”.
This will probably take a little while to complete. I’m using a Kingston DataTraveler DTSE9 and it took about 24 minutes 30 seconds to write 4.9GB.
Dmg To Usb Transmac
Your new USB stick should now be bootable, assuming that was the intended purpose of the DMG.
