Disable Secure Boot in Mac Recovery¶

Apple's Secure Boot implementation does not allow booting anything other than macOS or Windows when it is enabled (not even shim signed GRUB). We need to disable it:

Turn off your Mac

Turn it on and press and hold Command-R until the black screen flashes

Your Mac will boot in the macOS Recovery

Select your user and enter your password

Now, from the menu bar choose Utilities > Startup Security Utility

Enter again the password

Once in Startup Security Utility:

set Secure Boot to No Security

set Allow Boot Media to Allow booting from external or removable media

Install refind in ubuntu

sudo add-apt-repository ppa:rodsmith/refind  
sudo apt update
sudo apt install refind

Get windows booting again with gdisk https://wiki.t2linux.org/guides/windows/

Use zip file in this repository, overwrite the contents of /boot/efi/EFI/refind

and voila! nice triple booting macbookpro
