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 https://releases.ubuntu.com) 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.
Leave a comment if it helps.
