Installing Ubuntu 20.04.2 on Macbook Pro Mid 2012

Hello everyone. Been a while and I have a new blog entry so that I don’t forget how to do this if I ever have to do it again.

I got my girlfriend a new Macbook Pro M1 for Hanukkah and she gave me her old one (It’s a Macbook Pro Mid 2012, or 14,1). I was going to update it to Mac OS 11, but found out that it didn’t support it, so I figured I would try to revive life to it by installing Ubuntu on it. This proved to be harder than I expected, but if you keep reading, I’ll tell you how I finally did it. (I’m actually writing this blog from the laptop running Ubuntu.)

So, the installation was pretty straight forward. I burned Ubuntu 20.04.2 on a DVD (From and booted up the mac by inserting the DVD in the drive and holding down the “Option” key while booting up and I select the first EFI Partition to boot from by pressing the Up arrow after selecting it. It booted right into Ubuntu no problem.

I managed to install Ubuntu, and everything went smoothly. After installation, I noticed a weird error about MOK and EFI. I found out that Mac’s EFI wants a signed OS. To fix this, all I did was:

sudo su -
cd /boot/efi/EFI/ubuntu
cp grubx64.efi shimx64.efi

This will clear the black screen and error when booting.

Next, I ran sudo apt update & sudo apt upgrade -y to make sure I had all the updates to my laptop.

With the 20.04.2 update of Ubuntu, everything works out of the box with the Mid 2012 version of the Mac Book. If you run into any issues during the installation, leave a comment and I will try to help.

  1. Hello Lucas,

    How is the Performance. Is the Fan running hot?. Is the Wifi Drivers are working well?

    I am also thinking PopOS and Lubuntu/Kubuntu on these devices. Any reason you gone with Ubuntu?


    1. I have been using Ubuntu since Dapper Drake, and really like the distribution. I have actually started using Kubuntu 20.04.2 on this mac and it has been pretty solid. I notice it only gets hot when I have it plugged in, and every once in a while, the wifi will drop, but running sudo dhclient wlp2s0 gets it back up and running normally.
      Everything works out of the box, and updates work as well. Been pretty happy with it as my daily driver on my mac.

  2. One thing I have noticed now that I have had Ubuntu running on my Macbook is that the battery life has nearly doubled. While running MacOS X, the battery would only last about an hour, but since moving to Ubuntu 20.04, it now lasts about 3 hours on the battery.
