No, Ubuntu is the operating system, it has support for accessing HFS+ partition on USB. I just want to make sure your USB drive contains HFS+ partition. You can create an Ubuntu bootable USB using AIO Boot or Rufus. And among the first few things I did was to dual boot Mac OS X with Ubuntu Linux. I'll cover up Linux installation on Macbook in later articles as first we need to learn how to create a bootable Ubuntu USB drive for Mac in OS X. Select the USB drive to format. Click the Partition tab in the right side pane.

Developments in the last year have rendered certain of the procedures on this page sub-optimal. I've tried to point these out, but I haven't fully researched better replacements, and I lack the modern hardware on which to test some of the better methods on more recent 64-bit Macs. Thus, you may need to deviate from these instructions on modern computers. The Problem When installing Ubuntu Linux on an Intel-based Macintosh, most people follow any of several guides available on the Internet, such as. Most of these guides, however, rely on features of the Macintosh that are intended to enable it to boot Windows. In particular, these guides typically end up creating a configuration that boots Linux using its Compatibility Support Module (CSM), which provides BIOS emulation on the Mac. In this mode, the Mac sets up a Basic Input Output System (BIOS) layer that the OS can use, rather than rely on the that OS X uses to run on the computer. BIOS emulation is expedient, and it's the only way that most versions of Windows can boot directly on a Mac, but it's got several drawbacks: • Longer boot times—BIOS emulation is widely regarded as slowing the boot process. I've not tested this effect myself, so I'm not sure how significant it is. • Reduced graphics card flexibility—On some models with multiple graphics chipsets, you can't select which chipset to use in BIOS mode, but you can in EFI mode. ![]() My own Mac isn't one of the affected models, so I can't comment further on this issue. • Use of a hybrid MBR—Intel-based Macs use the rather than the more common partitioning system. Windows, however, can't boot from GPT disks on BIOS-based computers (which it thinks a Mac is thanks to Apple's BIOS emulation). Therefore, Apple uses an ugly and dangerous hack known as a in which a GPT data structure known as the protective MBR is altered to make the disk look like an MBR disk to Windows. The trouble is that hybrid MBRs frequently cause problems. In fact, even the Ubuntu installer often gets it wrong; it tries to be helpful by creating a hybrid MBR, but depending on your partition layout, it can create a partition table that the popular libparted-based partitioning tools won't touch. As far as I can tell, BIOS emulation mode only works when a hybrid MBR is present on the hard disk or when a BIOS-bootable optical disk is inserted in the optical drive.
