I originally thought it was as simple as using Bootcamp and then making a partition for Linux. But apparently installing Linux breaks the Windows installation.

I currently have High Sierra installed on my rBP 13" 2014. I wish to add Linux Mint 18.3 and Windows 10. What would be the general procedure?

Below is the output from the command diskutil list.

/dev/disk0 (internal, physical):
#:                       TYPE NAME                    SIZE        IDENTIFIER

  • I'm installing Linux Mint 18.3, Windows 10, and I have macOS on High Sierra. I have not installed Windows 10 or Mint yet. I'm on a rBP 13" 2014. What would be the general procedure? – PiAhoy May 21 '18 at 11:54
  • If I wanted to install another Linux distro(after those 3), what would be the procedure for that? – PiAhoy May 21 '18 at 17:48

You can install Windows via Bootcamp, Apple provides instructions for that. For Linux, follow these detailed instructions: https://www.lifewire.com/dual-boot-linux-and-mac-os-4125733. You can basically install as many Linux distributions as you have space for.

I have a dual boot setup with macOS High Sierra and Windows (via Bootcamp) and a Linux distribution on a USB stick (permanent installation, not a Live USB stick), effectively making it a triple boot setup. I am using rEFInd as boot manager. The only downside I experience is that I have to hold down the option key every time I reboot my MacBook and choose the OS to boot from, because otherwise it finds no OS to boot and displays some EFI error screen. Don‘t know why and if it will be an issue for you but not a big deal either.

    "every time I reboot my MacBook and choose the OS to boot from, because otherwise it finds no OS to boot and displays some EFI error screen" I've actually had a similar issue in the past, but I would just get a black screen on boot if I didn't press option/alt. Anyways, thanks so much for the useful answer – PiAhoy May 24 '18 at 13:55
  • Agreed @PiAhoy. +1 for this more useful answer than my pragmatic, why bother. The main reason to bother is to learn and as long as you have a backup, you can always do the erase and restore path I advocate. – bmike May 25 '18 at 2:33
  • not what I was trying to mean but okay – PiAhoy May 27 '18 at 11:22

Judging by the volume of questions we receive, no dual boot setup meets your safe and easy criteria. I would just be sure you have a really good backup of all your data and keep your setup media, license keys and setup scripts well documented and handy so you can always just wipe your drive and start over.

A macos wipe and reinstall from saved media takes 20 minutes. If you take a week to make the perfect setup, you’ll never recover that effort. Better to be able to set things up quickly than perfect a complicated setup.

Also, quality virtualization has such a low performance penalty, why even triple boot?
