I have a dual-boot MacBook Pro late 2013 with macOS Sierra and Windows 10 (BOOTCAMP) already installed. I want to install Ubuntu as a third OS. Is there any (easy) way to do it?

This answer installs Ubuntu on your computer without the use of third parity tools for either the installation of booting of Ubuntu. The Ubuntu file I downloaded was named ubuntu-16.10-desktop-amd64.iso. I assume you have created a bootable Ubuntu USB flash drive installer and have verified the contents. I also assume you have verified hardware compatibility by successfully booting the live version of Ubuntu. These instructions have been divided into the three main sections listed below.
- Create Space on the Drive for Ubuntu : This is accomplished by using the MacOS Terminal application to enter commands.
- Install Ubuntu : This uses the Ubuntu flash drive installer.
- Add Ubuntu to Startup Manager - Here you basically use the MacOS to move the necessary files to the proper locations. This will allow Ubuntu to be selected from the Startup Manager. You will not need rEFInd to boot Ubuntu.
Note: If another user has a different partition scheme than shown in this example, the post a comment to me and I will try to update my answer.
Create Space on the Drive for Ubuntu
For the purpose of illustrating the steps needed, I created a drive slightly larger than your actual drive.
The output from diskutil list disk0 is given below.

I decided to allow total of about 40 GB for Ubuntu. If you need a different size, then make the appropriate adjustments. I will be creating 3 new partitions for Ubuntu. A description for each is given below.
- A Swap partition. The size of this partition should be between 1 to 2 times the size of the memory installed in your Mac computer. I will be using a size of 800 MB. Obviously, the size you will be using will be much larger.
- A Ext4 Journaling file system partition to hold Ubuntu. This partition will consume most the approximately 40 GB of space I allocated for Ubuntu.
- An EFI System partition. This is required for Ubuntu to appear on the Mac Startup Manager. This manager appears when you turn on or restart your Mac and hold down the option key. The Startup Manager can be used to change the default startup disk (i.e. operating system) or can be used to temporarily boot from a startup disk. I have chosen size of 500 MB for this partition.
I have chosen to allow the Ubuntu installer to actually create the 3 new partitions. So at this point I only need to shrink the MacOS partition by approximately 40 GB and create 3 new placeholder partitions. The placeholders will be replaced later by the Ubuntu installer with the actual partitions described above.
The command to change to partitioning is given below. Since the MacOS partition is about 180 GB, I used a desired value of 140 GB (140G). Also, I used a value of 800 MB (800M) for the size of the new Swap partition. Since you will desire a larger size, then you will need to make the appropriate substitution. Note: The two values of 200 MB (200M) were chosen arbitrarily, these values will change later.

Note: The 3 placeholder partitions have be replaced by the partitions specified while installing Ubuntu.
To make Ubuntu appear in the Startup Manager, execute the following steps.
Mount the EFI System partitions by entering the commands given below.
diskutil mount disk0s1 diskutil mount disk0s5Use the Finder application to copy the
EFIfolder from volumeEFIto the volumeNO NAME.Remove the folders and files that were added to the
EFIvolume during the Ubuntu installation. To accomplish this, move the folderEFI/Ubuntuon theEFIvolume to the Trash.Remove the Microsoft related files from the
NO NAMEvolume. To accomplish this, move the folderEFI/Microsoftand the fileEFI/Boot/bootx64.efion theNO NAMEvolume to the Trash.Empty the Trash.
Copy the file
grubx64.efion theNO NAMEvolume from the folder/EFI/ubuntuto the folder/EFI/Boot.Rename the file
grubx64.efiin the/EFI/Bootfolder on theNO NAMEvolume to the namebootx64.efi.(Optional) Download a collection of icons from the sourceforge web site Mac icns. Use the Finder application to open the downloaded file
mac-ices.dmg, then enter the command below to copy the Ubuntu icon fileos_ubuntu.icnsto theNO NAMEvolume.cp /Volumes/mac-icns/OSX10.11.6/os_ubuntu.icns "/Volumes/NO NAME/.VolumeIcon.icns"This will add the following Ubuntu icon to the Startup Menu.
Note: When finished, you can use the Finder application to eject the
