To live boot into Linux on Mac, you will first have to create a Live USB for the distro you want. We’re demonstrating this using Ubuntu 14.10 “Yakkety Yak”, on a MacBook Air running the latest version of macOS Sierra. In this tutorial i will show you how to create bootable USB of Linux Mint ( 16 Petra, but it works for other versions also ) in Windows, Linux and Mac OSX. Linux Mint 16 Is released few days ago with many new features and shiny interface. You can see more about Linux Mint new features and download Link in my previous post. One thing I've learned when it's comes to imaging Macs is it's good to have options. When encountering Macs, its seems like there is always a challenge. No firewire ports for target disk mode, no easy way to remove the hard drive, or if the the hard drive is removed, you don't have the specific adapter needed to connect your write blocker to the drive. And of course, encryption. ![]() I am planning on doing several blog posts about different ways to image a Mac. Depending on the situation, some may work, some may not, but I just wanted to throw some options out in the Google soup mix. The first option I am going to go walk through is imaging a Mac with a Live Linux bootable USB. Many times cracking open something like a MacBook Air to grab a hard drive requires special tools and adapters which may not be readily available. If the Mac is already powered off, booting the Mac with a live Linux distro may be a good option. Once booted into Linux, an imaging tool with a GUI, like Guymager, can be used to create an image in E01 or dd format. For this post, I have selected the distro. CAINE stands for Computer Aided Investigated Environment. This distro was made specifically for computer forensics. Upon boot, CAINE 'blocks all the block devices (e.g. /dev/sda), in Read-Only mode.' The examiner must take active steps, which includes nice big warnings, to turn off this feature. While I did get Kali to work, it did not seem to offer the extra protection that CAINE did to keep the examiner for inadvertently mounting the wrong drive. If you are interested in making a Kali bootable USB drive for the Mac, I have included some brief instructions at the bottom of the post. This method was tested with CAINE 7.0, Rufus 2.9, and a MacBook Air Early 2015 model Create the Bootable USB The first step is to create a bootable USB drive on a Windows machine. Download the. Rufus is the Windows program that will create a bootable USB drive from the iso. ![]() Simply launch Rufus and select the CAINE iso as well as a blank USB drive bigger than 4GB. (NOTE - I tried various other tools to create the bootable USB drive, and not all of them worked when it came time to boot the Mac. Thanks to @APFMarc for the tip on Rufus). Below is a screen shot with the settings I used. From the CAINE website documentation: This new write-blocking method assures all disks are really preserved from accidentally writing operations, because they are locked in Read-Only mode. If you need to write a disk, you can unlock it with BlockOn/Off or using 'Mounter' changing the policy in writable mode. I personally prefer this extra layer of protection. Mount the USB drive that will hold the image Next, an external USB drive is needed to dump the image on. This external device needs to be mounted writable so the image can be placed on it. To do this, Read only mode needs to be turned off for any newly attached devices by using the Mounter program. Right clicking the Mounter icon in the task bar brings up the following dialog box. Now the drive can be accessed to create folders, dump the image to etc. Note - if I try and do the same with the other devices on the host drive (e.g.
