Dec 10, 2014 Click on 'Mac OS X Base System' in the bottom pane under 'BaseSystem.dmg' Click 'Restore' Drag 'Install OS X Mountain Lion' (the partition on the drive, not the top-level drive) as 'Destination'. I'm trying to use the BaseSystem.dmg to lay down a 2nd partition or Lion. I have in the parent config a 2nd partition created @ 2gb (when you install apple's default is 650mb), Journaled HFS+, checked This is a restore partition, selected the basesystem.dmg file, and checked re-image this poartition if it already exists.
This guide deals with 3 ways of making a boot disk from macOS, the first one is the fastest and is done via the Terminal from a command in macOS called createinstallmedia, the other 2 are older ways are done with a mixture of finder using Disk Utility and command line.
The first way can support macOS Big Sur, macOS Catalina, macOS Mojave or macOS High Sierraand further back to SIerra, El Capitan, Yosemite and Mavericks.
Quickest Way
Download the macOS version you need but don’t install.
Attach your USB stick/drive.
Launch the Terminal from /Applications/Utilities and enter the command below and then your password when prompted, be sure to change the ‘Untitled‘ name in the below command to your external disk name:
Let it do its thing and there you have it, one bootable macOS drive.
This really is a super simple way – however if using the Terminal fills you with fear and dread, there are some GUI apps that can get the job done namely DiskMakerX and a new imaging tool that can clone a new disk very quickly – AutoDMG, although AutoDMG can not work with macOS Big Sur
Alternative Ways of building a Bootable macOS Disk.
An alternative way to make a boot disk of macOS (but not macOS Big Sur), first of all, get the app or download via the App store, if downloaded it will file in the folder Applications.
The example below uses OSX Mavericks.
Lion Basesystem.dmg Download
Control / Left click Options, Show in Finder to get to the app, don’t install at this stage.
Located in the Applications Folder
Finding the InstallESD.dmg
To find the actual InstallESD.dmg file, control/left click the ‘Install macOS’ app and choose show contents – then navigate to Shared Support folder.
Control/Right click to show contents
Navigate to Shared Support folder to see the InstallESD.dmg file
Mount InstallESD.dmg
Double click to mount the image.
Make Invisible Files Visible
We need to see the BaseSystem.dmg inside the InstallESD.dmg
Crank open Terminal and run:
This will show all invisible files have a look inside the mounted InstallESD.dmg
Mount an External Disk
Attach a USB/external drive – this guide uses the external drive name called BootDisk, you need to make sure the format is correct, it needs to be Mac OSX Extended Journaled – if it’s not you can format that in Disk Utility.
Launch Disk Utility
Launch Disk Utility as found in Applications/Utilities and go to the Restore tab.
Drag BaseSystem.dmg to the Source field and your external disk to the Destination and click Restore.
This will mount your new macOS external disk and name it OSX Base System – but we need to add the packages.
Fix the Packages
Couple of things to fix in the newly created boot disk, remove the Packagealias at System/Installation/ folder
Now from the previously mounted InstallESD.dmg copy over the Packages folder to the same location where we just removed the alias above.
Will take a while as it holds all the install packages.
Job done now you can boot from the OSX 10.9 disk.
Make the Visible back to Invisible
If you want all to return back to normal and hide the system files run a couple more commands in the Terminal
How to create the OSX 10.9 Mavericks Bootable Drive just via Terminal
Just for the crazy ones……after Mavericks is downloaded….and again this assumes you external disk is named BootDisk
Mount the InstallESD.dmg buried deep in the app
Swap to the newly mounted image
This puts you back in the Finder in front of the newly mounted InstallESD.dmg, go back to Terminal and clone the BaseSystem.dmg to the remote USB drive
This will change ‘BootDisk‘ to ‘OS X Base System‘
Remove the existing Packages alias link from the newly restored image
Copy the full OSX Mavericks Packages over to the new image….takes a while
And there it is! – to eject the new bootable USB OSX Mavericks 10.9 disk ‘cd’ to home and eject
Now you can boot up from your newly bootable disk and either Install OSX10.9 on another device or use the Terminal/Disk Utility or Firmware Password Utilities on another device. Marvel spider man full pc.
Yay, finally a gold master release has been established. Now to get our hands dirty on the newest OS from Apple. I could have attempted to write up a tutorial on how to install Lion on your hackintosh with the beta release, but if you recollect my previous post about Lion, you’ll remember I was testing the beta version out on my macbook pro. Though I was very pleased with the operating system and for a beta release it was very stable, it still had minor annoying glitches and some software conflicts. Considering I use my hackintosh for college, I can’t really afford a half-ass OS on my main machine that wouldn’t work with my chemistry software. Now all that has changed (hopefully). I just got a hand of the Gold Master Build and I am making preperations to my harddrive and machine to have a fresh install of OSX Lion 10.7.

Things to Note about the Gold master and 10.6.8 release:
- “Golden Master” refers to the final release version. 11A511 is listed as GM. You will be able to update as Apple releases 10.7.x maintenance builds.
- There have been speculations about Lion only being installed through an update from Snow leopard 10.6.8. This I will verify in the upcoming posts soon. Just after this hell week subsides in course work.
- 10.8.0 Darwin kernel with native Sandy Bridge support. This means that going forward, all Sandy Bridge systems can use default iBoot + MultiBeast method. (tonymac’s site)
- SATA3 6gbps now recognized and functional on Sandy Bridge. (tonymac’s site)
- Includes drivers for Sandy Bridge Intel HD 2000/3000 Integrated Graphics (No Injector Yet) (tonymac’s site)
- Includes drivers for AMD 6xxx Graphics cards (tonymac’s site)
- App Store Update to “Get Ready for Lion” (tonymac’s site 10.6.8)
