Are you familiar with the concept of “habit fields”? They’re these magical auras we give to everyday objects, assigning them purpose and allowing us to focus our awareness to accomplish tasks faster. But habit fields can work against you as well, if you’re not careful:
If you’ve been trying to do everything from one place and one device, then you may need to make a conscious decision to divide different modes of behavior.Jack Cheng, Habit Fields (2010)
One device you may be trying to do everything from one place is the MacBook Pro. With the beefy specs on the flagship Apple notebook it can be easy to piledrive too many activities all into one place, affecting your Mac’s habit field.
But there’s a trick you can use to divide different modes of behavior on a Mac. And that’s to add a second operating system and dual-boot. Here’s how to install and dual-boot Linux Manjaro alongside macOS Mojave on a MacBook Pro.
Test Driving Manjaro
You don’t need to make any permanent changes to your Mac to try Manjaro. In fact, all you really need is a reasonably-sized thumb drive, balenaEtcher and a few gigs of bandwidth to download and try one of the 11 different editions:
For people who want a reliable and fast desktop…
Xfce is a lightweight desktop environment for UNIX-like operating systems. It aims to be fast and low on system resources, while still being visually appealing and user friendly. Xfce embodies the traditional UNIX philosophy of modularity and re-usability. It consists of a number of components that provide the full functionality one can expect of a modern desktop environment. They are packaged separately and you can pick among the available packages to create the optimal personal working environment.
For people who want a modern and very flexible desktop…
KDE is a feature-rich and versatile desktop environment that provides several different styles of menu to access applications. An excellent built-in interface to easily access and install new themes, widgets, etc, from the internet is also worth mentioning. While very user-friendly and certainly flashy, KDE is also quite resource heavy and noticably slower to start and use than a desktop environment such as XFCE. A 64 bit installation of Manjaro running KDE uses about 550MB of memory.
For people who look for a traditional desktop…
This edition is supported by the Manjaro community and comes with Cinnamon, a desktop based on modern technology that keeps known and proven concepts.
For power users and developers…
This edition is supported by the Manjaro community and comes with openbox, a highly configurable, next generation window manager with extensive standards support…
For power users and developers…
This edition is supported by the Manjaro community and comes with Awesome, a highly configurable, next generation framework window manager for X.
For people who want a simple an elegant desktop…
This edition is supported by the Manjaro community and comes with Budgie, the desktop of the Solus project. Budgie focuses on providing a simple-to-use and elegant desktop that fulfills the needs of a modern user.
For people who look for a traditional experience…
This edition is supported by the Manjaro community and comes with Mate, a desktop environment that continues the legacy of traditional user experience while carefully improving and modernizing it when needed. This preview is not suitable for production environment.
For people who want a tiling window manager…
This edition is supported by the Manjaro community and comes with i3, a tiling window manager.
For people who want to configure Manjaro from the ground up…
Manjaro-Architect is a fork of the famous Architect Linux installer by Carl Duff, that has been modified to install Manjaro instead of Arch Linux. It is a netinstaller that downloads always the latest packages, so your system is always up to date after installation, regardless of how old your install media is.
For people who want a simple and elegant desktop…
This edition is supported by the Manjaro community and comes with the Deepin desktop that provides a very beginner-friendly and elegant experience.
For people who want a simple and elegant desktop…
This edition is supported by the Manjaro team and comes with the GNOME 3 desktop that breaks with traditional concepts and allows users to focus on their tasks. Desktop-specific applications are crafted with care and clearly defined by guidelines that make them more consistent to use.
Once you’ve selected an edition go ahead and etch it to the thumb drive, reboot and hold Option during start-up to dual-boot from USB as described here.

After test driving a few the edition I selected was Cinnamon.
Booting Manjaro from Hard Disk
Once you’ve settled on an edition you can dual-boot it alongside macOS Mojave directly from your Mac’s internal hard disk – no special tooling required.1
While booting from disk isn’t strictly necessary doing so will give you a better opportunity to form a strong habit field given its permanence and the steps required to get there: the first of which is creating a backup.
Create System Backup
Before making any changes to your Mac’s internal hard disk take the time to create a proper backup of macOS Mojave. In doing so you’ll likely uncover many things you don’t need. Get rid of or archive as much of them as you can.
Purging clutter will improve your machine’s existing habit field even before you begin to realize the additional benefits received after installing Manjaro.
Shrink Macintosh HD Volume
With your back-up complete use the macOS Disk Utility app to Partiton your Macintosh HD volume, adding a new partition to make space for Manjaro. Several suggestions I saw online lobbied for a 20–25 GB partition for *nix distros. I’d say 20–25 GB is reasonable… if you plan to run out of space in two months.
Depending on your intentions, and unless this is a test installation, aim for 20% or so of your SSD to give yourself ample room to grow into Manjaro:
When you Apply the new partition Disk Utility will automatically shrink your Macintosh HD volume. Go ahead and do that now or before proceeding, selecting
ExFAT as the Format option and considering any alerts presented.
When the operation is finished you’ll receive the result and a log:

If successful, confirm the size and format of the new partition:
When everything looks good proceed to install Monjaro to the disk.
Install Manjaro to Apple SSD
To install Manjaro to the to internal drive partition boot once more from USB, connect to the Internet and run Install Manjaro using the optical disk icon 💿 on the Manjaro desktop as shown here:
Complete the installer wizard up to the Partitions section then:
- Choose the Replace a parition option
- Select the new partition created while shrinking (i.e. 100 GB partition)
- Check the Encrypt system checkbox and enter a password
You should end up seeing something like this:
From there complete the rest of the wizard, review the summary, and then click Install followed by Install now. Installation should complete in 5–10 minutes.
When installation is finished you will be notified with an All Done message:
Then restart your computer as you would normally (power cycle if needed) and brace yourself for a black screen with some text that looks like this:

Oh snap you bricked your Mac!
Just kidding. That’s LUKS pre-boot authentication prompting you for the password to your encrypted volume. Enter the password set during Manjaro installation and press Enter…
You’ll see Slot 0 opened briefly flash on the screen before being transported to your new Manjaro desktop following a short boot sequence:
And with that you’ve completed installing Manjaro to your Apple SSD.
Select Your Boot Option
If you’d like to boot into macOS hold the Option key during system boot and select Macintosh HD. To boot to into Manjaro simply enter your LUKS password after restarting your computer. And if for some reason this isn’t feasible for you you now know everything you need to reinstall Manjaro without encryption.
Some MacBooks have an Apple T2 Security Chip which you may need to deactivate in order to use Linux. See About Security on Apple Support for more info.
In this tutorial I covered the concept of habit fields and how to create one by dual-booting Linux Manjaro alongside Mojave on a MacBook Pro.
Not only will dual-booting increase the utility and enjoyment of your Mac, your new Manjaro operating system will give you the ability to focus your awareness and get creative in ways you never before imagined possible.
