How to Run Linux on a Mac: A Step-by-Step Guide
Linux offers unmatched flexibility, security, and customization, making it a popular choice for developers, hobbyists, and those looking to breathe new life into older Macs.
Whether you have an Intel-based Mac or an Apple Silicon model, you can run Linux using virtualization, dual-booting, or a live USB. This guide explains the best methods to get Linux running on your Mac, with clear steps and practical tips.
Transform Your Mac with Linux: A Complete Guide
Why Run Linux on a Mac?
Linux is open-source, highly customizable, and lightweight, making it ideal for:
- Developers: Access powerful tools like Docker or programming environments.
- Older Macs: Revive outdated hardware no longer supported by macOS.
- Privacy and Security: Benefit from Linux’s robust security features.
- Exploration: Try a new OS without abandoning macOS.
Popular distributions (distros) like Ubuntu, Linux Mint, and Fedora are user-friendly and compatible with Macs. Let’s explore the main methods to run Linux on your Mac.
Method 1: Run Linux Using Virtualization
Virtualization lets you run Linux in a virtual machine (VM) alongside macOS, ideal for testing or using Linux without altering your system. Tools like Parallels Desktop and UTM are excellent choices.
Using Parallels Desktop
Parallels is user-friendly and supports both Intel and Apple Silicon Macs.
- Download Parallels: Get the free 14-day trial from the Parallels website and install it.
- Get a Linux ISO: Download an ISO file for your preferred distro (e.g., Ubuntu) from its official website. Ensure it’s ARM64 for Apple Silicon or x86_64 for Intel Macs.
- Create a VM: Open Parallels, click “File > New,” and select “Install Windows or another OS from a DVD or image file.” Choose your Linux ISO and follow the prompts.
- Configure Settings: Allocate disk space (20-50GB recommended) and CPU cores. Avoid over-allocating to preserve macOS performance.
- Run Linux: Launch the VM to install and use Linux within Parallels.
Pros: Easy setup, no partitioning needed, runs alongside macOS.
Cons: Paid software after trial, performance slightly lower than native.
Using UTM (Free Option)
UTM is an open-source tool for virtualization and emulation, perfect for budget-conscious users.
- Install UTM: Download UTM from its official website or Mac App Store and install it.
- Download Linux ISO: Choose an ARM64 distro for Apple Silicon (e.g., Ubuntu 22.04) or x86_64 for Intel.
- Set Up VM: Open UTM, click “+” to create a new VM, select “Virtualize” for ARM or “Emulate” for x86 on Apple Silicon, and load your ISO.
- Configure Resources: Assign disk space (20GB minimum), RAM, and CPU cores. Optionally share a macOS folder with the VM.
- Boot and Install: Start the VM, follow the Linux installer, and set up your distro.
Pros: Free, supports both virtualization and emulation, great for Apple Silicon.
Cons: Slower emulation for x86 distros on M-series Macs.
Method 2: Dual-Boot Linux with macOS
Dual-booting lets you choose between macOS and Linux at startup, offering native performance. This method requires partitioning your drive and is best for Intel Macs or Apple Silicon with Asahi Linux.
For Intel-Based Macs
- Back Up Your Mac: Use Time Machine to save all data before partitioning.
- Download Linux ISO: Get Ubuntu, Linux Mint, or Fedora from their official sites.
- Create a Bootable USB: Use balenaEtcher to flash the ISO onto a USB drive (minimum 4GB). Open Etcher, select the ISO, choose your USB, and click “Flash.”
- Partition Your Drive:
- Open “Disk Utility” from Applications > Utilities.
- Select your main drive, click “Partition,” and add a new partition (20GB minimum, MS-DOS FAT format).
- Apply changes and note the partition size.
- Install Linux:
- Insert the USB, restart your Mac, and hold the “Option” key to access the startup menu.
- Select the USB drive and choose “Try or Install Ubuntu” (or your distro).
- Follow the installer, select “Something Else,” and choose your new partition for Linux. Set a swap partition (half your RAM size) if needed.
- Install rEFInd (Optional): To manage dual-booting, install the rEFInd boot manager after Linux setup to easily switch between macOS and Linux.
For Apple Silicon Macs (Asahi Linux)
Asahi Linux is the primary native option for M-series Macs, though it’s still in development and lacks features like Thunderbolt support.
- Back Up Your Mac: Ensure all data is saved.
- Download Asahi Linux: Visit the Asahi Linux website and follow their installer script.
- Run Installer: Open Terminal, run the Asahi installer, and choose to dual-boot with macOS. The script partitions your drive and installs Fedora-based Asahi Linux.
- Boot Linux: Restart and select Asahi Linux from the startup menu.
Pros: Native performance, full hardware access on Intel Macs.
Cons: Risk of data loss, complex setup, limited support for M-series Macs.
Method 3: Run Linux from a Live USB
A live USB lets you try Linux without installing it, perfect for testing or portable use.
- Download Linux ISO: Choose a distro like Ubuntu or Linux Mint.
- Create Live USB: Use balenaEtcher to flash the ISO onto a USB drive.
- Boot from USB:
- Insert the USB, restart your Mac, and hold the “Option” key.
- Select the USB drive and choose “Try [Distro] without installing.”
Pros: No installation required, preserves macOS.
Cons: Slower performance, no persistent storage unless configured.
Tips for a Smooth Linux Experience on Mac
- Choose the Right Distro: Ubuntu is beginner-friendly and similar to macOS. Linux Mint is lightweight for older Macs, while Fedora suits advanced users.
- Clean Up First: Use tools like CleanMyMac X to free up space before partitioning or installing VMs.
- Check Compatibility: For Apple Silicon, use ARM64 distros or Asahi Linux. Intel Macs support most distros natively.
- Sync Data: Use ChronoSync Express to sync files between macOS and Linux for seamless workflows.
- Test on External Drive: Install Linux on an external SSD to avoid altering your internal drive.
- Prepare for Drivers: Wi-Fi and Bluetooth may require Ethernet or third-party drivers during setup.
Final Thoughts
Running Linux on your Mac opens up a world of customization and performance benefits, whether you’re reviving an old MacBook or exploring new tools on an M-series iMac.
Virtualization with Parallels or UTM is the easiest and safest option, while dual-booting offers maximum performance for committed users.
A live USB is great for casual exploration. Always back up your Mac before making changes, and choose a distro that matches your needs.
