Single Boot Kali on Mac Hardware

Kali Linux Installation Requirements

Since the release of Kali Linux 1.0.8, Kali Linux supports EFI out of the box. This added feature simplifies the process of getting Kali installed and running on various Apple MacBook Air, Pro, and Retina models.

The make/model/year of the device will determine how successful your experience will be, with newer devices having a better chance of working. Pre-installing rEFInd may also increase the odds of success on older devices.

This guide will show you to replace OSX with Kali Linux, with the option of encrypting the partition. However, if you wish to keep OSX, you will want to refer to our dual-boot guide instead.

Installation Prerequisites

  • A minimum of 10 GB disk space for the Kali Linux install.
  • A minimum of 512MB RAM.
  • For devices older than late 2012, you will need a blank DVD.
    • USB booting may not work without rEFInd installed.
  • For devices newer than late 2012, you’ll need a blank DVD or a USB drive.
  • OSX 10.7 or higher.

Preparing for the Installation

  1. Download Kali linux.
  2. Burn the Kali Linux ISO image to a DVD or copy the image to USB drive.
  3. Backup any important information on the device to an external media.

Kali Linux Installation Procedure

  1. To start your installation, power on the device and immediately press and hold theOption key until you see the boot menu.

01-bootNow insert your chosen installation media. If everything was successful, you will seetwo volumes (EFI & Windows). Even though Kali Linux is based on Debian, Apple detects it as Windows.

Select the Windows volume to continue.

      • If you only see one volume (EFI), then the installation media is not supportedfor this device.

You may wish to install rEFInd and try again.

      • If you select the EFI volume, the booting will hang at this point and you will notbe able to continue.

02-boot-kaliYou should be greeted with the Kali boot screen. You are free to choose ‘Live’, ‘Graphical Install’, or ‘(Text-Mode) Install’ to install. In this example, we picked ‘Graphical install’.

03-boot-menuSelect your preferred language and then your country location. You’ll also be prompted to configure your keyboard with the appropriate keymap.

05-lanuageThe installer will copy the image to your hard disk, probe your network interfaces, and then prompt you to enter a hostname and domain name for your system. In the example below, we’ve entered ‘kali’ as our hostname.

      • If the setup detects multiple NICs, it may prompt you which one to use for the install.
      • If the chosen NIC is 802.11 based, you will be asked for your wireless network information before being prompted for a hostname.
      • If there isn’t a DHCP service running on the network, it will ask you to manually enter the network information after probing for network interfaces.
      • If Kali Linux doesn’t detect your NIC, you either need to include the drivers for it when prompted, or generate a custom Kali Linux ISO with them pre-included.

06-hostnameEnter a robust password for the root account.

07-root-passwordNext, set your time zone.

08-time-dateThe installer will now probe your disks and offer you five choices. In our example, we’re using the entire disk on our computer and not configuring LVM (logical volume manager), so we selected ‘Guided – use the entire disk’.

      • Experienced users can use the ‘Manual’ option for more granular configuration options. This option will also allow you to set up encrypted LVM, so Kali Linux would be fully encrypted. The screen afterwards will prompt you for the password. You will have to enter the same password every time you start up Kali Linux.
Kali will automatically securely wipe the hard disk before asking for the LVM password. This may take ‘a while’ (hours) depending on the size and speed of the drive. If you wish to risk it, you can skip it.

09-partitionThe installer will ask you to confirm which disk to erase. Double check then confirm the selection.

10-partitionThe next stage is to select the partition structure you want to use. We will go ahead and use the default option and have everything on one partition. Afterwards, the installer will display an overview. If you agree with what it suggests, press the continue button.

11-partitionNext, you’ll have one last chance to review your disk configuration before the installer makes irreversible changes. After you click Continue, the installer will go to work and you’ll have an almost finished installation.

12-partitionThis screen configures the use of our Internet network mirrors. Kali can use our online central repository to distribute applications to keep packages up-to-date and allow for additional programs to be installed more easily. Should you need to enter any appropriate proxy information, the next screen will allow you to enter details.

If you select ‘NO’ in this screen, you will NOT be able to install packages from Kali repositories until you alter your sources.

13-package-managerNext, install the GRUB bootloader.

14-grubFinally, click Continue to finish installing Kali Linux. It is highly recommend that you restart your machine at this stage.
Once the install has finished, repeat the first few steps again to boot into ‘Live mode’ once more.

15-finishIf the gdisk package isn’t included your Kali Linux ISO, you need to install it.
If you enabled the network repository during the setup, this can easily be done as follows:

apt-get update
apt-get install gdisk

We are now going to convert the MBR to a hybrid, which will allow for Apple’s EFI to detect and boot to GRUB.

WARNING! Hybrid MBRs are flaky and dangerous! If you decide not to use one,
just hit the Enter key at the below prompt and your MBR partition table will
be untouched.

Type from one to three GPT partition numbers, separated by spaces, to be
added to the hybrid MBR, in sequence: 2
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): y

Creating entry for GPT partition #2 (MBR partition #2)

Unused partition space(s) found. Use one to protect more partitions? (Y/N): n

Recovery/transformation command (? for help): w

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sda.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.
  1. After that is complete, all that is left is to reboot, take out the installation media, and enjoy Kali.
