This will add the following Ubuntu icon to the Startup Menu. cp /Volumes/mac-icns/os_ubuntu.icns /Volumes/EFI/.VolumeIcon.icns The Ubuntu icon file os_ubuntu.icns to the EFI System partition.

When finished, restart and hold down the option key to.If you wish to install a different Linux distribution, post a command and I will verify if these instructions will work. The steps are given below for the Ubuntu Linux distribution. The process of making a Linux distribution appear on the Startup Manager is a fairly trivial. Normally, this is the first partition on a Mac computer. Most Linux distributions install grub and other files in the first EFI System partition on a Mac computer.

After installing a Linux distribution, you will need to move a few files around in order for the Startup Manager to recognize and boot the Linux distribution. The Startup Manager is contained in the the firmware that is already installed in your Mac. Instead of using rEFInd, you can use the Startup Manager to boot most Linux distributions. In other words, if your Mac has Mountain Lion (OS X 10.8) or a newer version OS X (macOS) installed, then you can use these instructions. Note: These instructions are for Mac models with 64 bit EFI firmware. You can still employ step 7, if you want an Ubuntu icon to appear in the Startup Manager.

In other words, the Ubuntu 18 installer will automatically create files in the proper locations for Ubuntu to appear in the Startup Manager. Note: The introduction of Ubuntu 18 has made these instructions obsolete.
