Advertisement Linux has long been synonymous with bootable flash drives, whether it’s to fix some sort of problem with your primary OS, or for trialling and installing USB are great for running portable versions of Linux. Here are the most useful Linux distributions to run from a USB drive. There are a few ways to get a create live USB sticks that will boot on your Mac. You can go the freeware route for an easy option, or put a little bit of time into creating the drive yourself using Terminal. Today we’ll cover both these methods! First: Prepare Your USB Drive Make sure you choose the right USB drive for the job, and that it’s formatted correctly to avoid any problems. Some Linux variants may require larger volumes, so pay attention to the requirements when downloading. Others don’t have any strict requirements, but formatting to FAT beforehand is a good idea: Warning: Everything on your drive will be erased if you do this!. Insert your USB drive into your Mac and launch Disk Utility (under Applications Utilities, or Today we're going to share our favourite good Mac habits, while desperately trying to forget the bad ones.).
Select your USB device in the menu on the left, then click Erase. Give it a name (or not) and choose MS-DOS (FAT) under “Format” and GUID Partition Map under “Scheme.”. Hit Erase to apply the changes. If it fails, try again — sometimes the system doesn’t unmount the volume in time and the process will be unable to complete. Generally speaking anything above 4GB will do the job (I used an 8GB Lexar for this tutorial). If you have persistent problems, try another USB drive. Method 1: Create a Live USB Using Etcher (Easy) is a free open source tool for burning disc images onto USB and SD drives.
It’s a relatively recent addition to the When most people think open source, they think Linux. But Mac OS X has its share of quality open source programs as well — and a bunch of them aren't available for Linux or Windows., and it makes creating bootable devices completely foolproof:. Grab your desired Linux image, then and install it. Insert your USB stick, then launch Etcher. Click Select image and find the Linux image you downloaded — Etcher supports.IMG,.ISO and.ZIP among others.
Ensure the correct USB device is selected — hit Change to see a list of connected devices. Finalize the process by clicking Flash! And wait for the process to complete.
Follow these steps: 1. Using a Mac with at least OS X 10.6.8 installed, access the Mac App Store and download the Lion (10.7) or Mountain Lion (10.8) app installer. Insert the USB drive into the Mac and launch Disk Utility. Click on the USB drive from the left-hand menu and select the Partition tab.
You’ll likely see an error message warning you that your USB drive isn’t compatible with your Mac. That’s normal — simply eject and go. Your bootable Linux USB drive is now ready, you can now skip to the Booting Your USB Drive section below.
Method 2: Create a Live USB Using the Terminal (Moderate) If for some reason you don’t want to use Etcher (maybe you’re on an incompatible version of macOS), you can accomplish this task using the command line. This is possible using Terminal, your Mac’s built-in command line interface. While this method requires a little more thought and patience on your part, it’s actually pretty straightforward. You might even learn a thing or two, plus you’ll feel smart afterwards. Assuming you’ve formatted your drive as per the instructions at the start of this tutorial, here’s how it works: 1. Convert Your.ISO Launch Terminal and take note of where your Linux disc image is stored in Finder. Convert your image (usually an.ISO) to an.IMG file using the hdiutil convert command: hdiutil convert /path/to/downloaded.iso -format UDRW -o /path/to/newimage Replace /path/to/downloaded.iso with the location of your own.ISO (you can drag and drop directly into the Terminal window if you want) and /path/to/newimage to wherever you want the new image file to be created. You’ll likely be able to identify the drive by its name, it’s format, and its size using a process of elimination.
Take a note of the listing under the IDENTIFIER column, then unmount the drive using the following command: diskutil unmountDisk /dev/diskX You’ll need to replace diskX with the corresponding number, e.g. Disk3 — if successful Terminal will report that the disk was unmounted. If you’re having trouble unmounting a drive, you can launch Disk Utility, right click on a drive, then choose Unmount (don’t eject the drive, though). The final step is to write the image to your USB stick, using the dd command: sudo dd if=/path/to/newimage.dmg of=/dev/diskN bs=1m Replace /path/to/newimage.dmg with the path to the file we created in step 1 (again, drag and drop works best), and diskN with the location we identified earlier. You’ll need to authorize with your administrator password immediately afterwards, since we used the sudo command.
You’re done, and your drive is ready for booting. Booting Your USB Drive Assuming all went well, you’ll now have a USB drive that will let you boot Linux. You can plug it into the Mac you want to use it on, then shut down the computer.

Depending on what you’re using, you may get another menu which acts as a bootloader for your particular flavor of Linux. If you have problems, or your USB drive won’t show up, try running the process again, try using an alternative method above, try a different USB stick or port, and consult your respective distro’s help documentation. The Best Way to Try Linux on Your Mac Assuming all went well, you now have Linux running on your Mac and you can test it out or install it outright if you’re tired of macOS. You still have an If you are looking to ditch macOS, you may want to delete your recovery partition for some extra disk space.
