Who said you need to dust off $1200 to work on Mac? If you want, you can install it on your computer too. Yes, it wont give you the same experience, but you would be atleast working on Macintosh OS.

DiskMaker X (formerly Lion DiskMaker) is an application built with AppleScript that you can use with many versions of OS X/macOS to build a bootable drive from OS X/macOS installer program (the one you download from the App Store). As soon as you launch the application, it tries to find the OS X Install program with Spotlight. Apple Mac OS X Lion is now available to general public. The Mac OS X 10.7 Lion is available for installation only from the Mac App Store. This guide will teach you how to create a bootable USB Flash drive of Mac OS X Lion 10.7 and install Lion from USB, rather than downloading it from Mac App Store on each and every Mac computer you own.

I have come up with a step by step guide to install Mac OS X Lion on computer using USB without much of fuss. In this tutorial, we would be using a nifty tool, UniBeast which would make the whole installation business simple.

Steps To Install Mac OS X Lion On Computer Using USB

Pre – requisites

  • First thing you need is a bootable USB which needs to be created on Mac machine
  • Storage device or pen drive
  • Installation files for Mac OS X Lion. (Either get it from App Store or buy its installation USB drive)

Create Bootable USB Drive

  • Plug in the storage device or pen drive into the Mac machine and launch its Disk Utility by navigating as Applications > Utilities
  • We need to creation partitions on the pen drive now. So, choose the pen drive from the panel on left hand side and click on Partition. Now click on Current and choose 1 Partition
  • Now name it the way you want (lets say BootME) and then click on Options and choose Master Boot Record

Use UniBeast

  • For the below steps, make sure your Mac OS X Lion Installation USB is mounted, and if you want to install the same from Mac App Store, then ensure that its available in Applications folder
  • Since we are good to go ahead, download and install UniBeast. This would also require you to complete some registration
  • Run UniBeast and when it asks to choose a destination, choose the USB drive that you have formatted in the above steps
  • Now choose the installation type, and then choose the third option too if you are installing Mac OS X Lion on laptops

Setup Your Computer

  • Like every other OS installation, you need to do some tweaking with the BIOS settings
  • Press F10, F12 or DEL (whatever works on your computer), to enter into BIOS settings
  • Set USB-HDD in the highest order or boot priority sequence
  • And also set HDD SATA mode to AHCI, ACPI to S3 and Xtreme hard drive to Disabled
  • Now when you restart your computer, Chimera boot screen would pop up. But this will happen only if bootable USB drive is plugged in. And to start the installer, you can use the below options:
    • For AMD Radeon 6670 type, PCIRootUID=0 (Nvidia cards are supported by default) and for any other graphics support, type GraphicsEnabler=No
    • Single User mode, type -s
    • Verbose mode, type -v (use for troubleshooting as it gives detailed description of problems)
    • Sage mode, type -x (use this if you fail to boot into installer)

Prepare The Hard Disk With Lion OS
