Mac Support

As of v3.0.0, Omarchy has built-in support for Intel Macs. There are a couple of known limitations at the moment, but as long as you're aware and OK with those; you can breathe some new life into your old Macs by loading Omarchy.

Please note that installing on an M-series Mac is not directly supported at this time. You can find out more about the state of this in #omarchy-on-other in our Discord.

In a simple test, we were able to achieve 36% performance gains on a 2019 MacBook Pro just by installing Omarchy.

Installing Omarchy on Mac

Omarchy only supports being the only OS installed at the moment. During the installation, the drive will be wiped and MacOS will no longer be bootable.

You can still restore it later via Internet Recovery if you'd like.

For the sake of this part, we'll assume you've already reviewed Getting Started and have your USB drive ready. If you don't go ahead and do that now.

Disable Secure Boot

It is necessary to disable Apple's Secure Boot in order to boot the bootable USB, as well as the OS. To disable it, perform the following:

  1. Turn off your Mac
  2. Turn it on and immediately press and hold Command-R until you see the loading screen appear
  3. Select your user and enter your password if prompted
  4. Once in the recovery screen, choose Utilities > Startup Security Utility from the menubar
  5. Enter your password when prompted to authenticate
  6. Choose "No Security" from the Secure Boot options
  7. Choose "Allow booting from external or removable media" from the External Boot options

Start the Installation

  1. Insert the USB drive
  2. Restart your Mac and immediately press and hold Option until you see a screen of boot devices
  3. Select the orange EFI Boot device
  4. Proceed with the install as normal
