EFI-Booting Ubuntu on a Mac EFI-Booting Ubuntu on a Mac by Rod Smith, Originally written: 1/2011; Last Web page update: 6/17/2013 (last major update: 5/4/2012) I'm a technical writer and consultant specializing in Linux technologies.

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.

Mac OS El Captain was publicly launched on Wednesday the 30th of September last year. This tutorial provides a clear and systematic guideline with respect to downloading and installing Mac OS X El Capitan on a PC. MacOS, the operating system previously known as Mac OS X, is beautiful, stable, and typically attached to a $1000+ MacBook / iMac. If we want to run macOS on a Windows PC, without the very particular hardware required for Hackintosh, a Mac OS X virtual machine is the next best thing. Also the.bmp image is now 800x600, so the image from the award bios will have a black frame around it as it is 640x480. I have yet to try an image at 800x600 but the old one at 640x480 worked so a different resolution should work but its late were i am so ill try it tomorrow.

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.
