This guide deals with 3 ways of making a boot disk from OSX 10.9 Mavericks the first one is the fastest and is done via the Terminal from a new command already in OSX Mavericks called createinstallmedia , the other 2 are older ways when Mavericks was in development and are done with a mixture of finder using Disk Utility and command line.

Quickest Way

Download Mac OSX 10.9Mavericks 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 Mac OSX 9 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.

Alternative Ways of building a Bootable Mavericks OSX Disk.

To make a boot disk of OSX 10.9 Mavericks, first of all get the app or download via the App store, if downloaded it will file in the folder Applications.

Make Invisible Files Visible

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 calledBootDisk, you need to make sure the format is correct, it needs to be Mac OSX Extended Journaled – it its 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 OSX 10.9 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

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

The next massive update of the macOS, macOS Mojave that was put to test for a while, is now officially out. As described at the event, it will definitely include system-wide Dark Mode, Apple News, Desktop Stacks and a lot more. With these features in count, there will be much more small and huge features that were not in list such as improved Siri, favicons and tracking protection in Safari and much more.

As of appearance, most users had appeal for a dark mode which should cover most of the apps at least default apps. Including these, there was a FaceTime bug that Apple fixed with a supplemental update to improve reliability and ease of access.

Getting macOS Mojave is simple in Mac. All there is needed to do is head over to the App Store, search for it and click Get. It will then start loading. On Windows, that’s completely different plus complex. For installing macOS Mojave on Windows, it takes to prepare or pick up Mojave ISO or Mojave VMware & VirtualBox image first. Both of these files are entirely difficult to figure out. While we’ve done that for you already but for some reason, creating it will take no more than a couple of minutes.
