How to create a bootable USB drive for Ubuntu MATE. If you want to make a microSDHC using Windows we recommend: 7-Zip to extract the.
Ubuntu images (and potentially some other related GNU/Linux distributions) have a peculiar format that allows the image to boot without any further modification from both CDs and USB drives. A consequence of this enhancement is that some programs, like parted get confused about the drive's format and partition table, printing warnings such as: /dev/xxx contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted - possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Both the primary and backup GPT tables are corrupt.
Try making a fresh table, and using Parted's rescue feature to recover partitions. Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes. All these warnings are safe to ignore, and your drive should be able to boot without any problems. Refer to if you want to learn more. You can set the ETCHERFAKES3LATESTVERSION environment variable to a valid semver version (greater than the current version) to trick the application into thinking that what you put there is the latest available version, therefore causing the update notification dialog to be presented at startup. Note that the value of the variable will be ignored if it doesn't match the release type of the current application version.
For example, setting the variable to a production version (e.g. ETCHERFAKES3LATESTVERSION=2.0.0) will be ignored if you're running a snapshot build, and vice-versa. See for more details about release types.
Note: These instruction have been updated for use with Ubuntu 18. 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.

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.
