Since Mac OS X 10.7, Apple proposes to get macOS (ex-OS X) major updates from the Mac App Store, through a macOS / OS X Install application. Download, install, Mac updated. Beautiful.

But what happens if you wish to restore your Mac from scratch (with the hard drive or SSD formated)? Or if you wish to install the new OS on many Macs ? Or help a friend with a slow Internet connection? That’s when you wish you could get a good ol’ DVD to install the OS…

DiskMaker X helps to easily build  a boot disk from a USB thumb drive, an external Firewire or Thunderbolt drive,  an  SD-Card… If you are a Mac technician or consultant, you’ll be able to easily upgrade your customers’ machines without having to re-download the app for each Mac. Especially useful when your customer has a very slow Internet connection !

As soon as you launch the application, it tries to find a valid macOS /OS X Install app with Spotlight. Then, it proposes to create a bootable install disk on an external drive.

To build a bootable disk, you’ll need an 8 GB (minimum) USB thumb key drive, a USB, Firewire or Thunderbolt drive or an SD-Card, and a macOS install app. Here is a list of links to help you get the Install app.

WARNING! DiskMaker X will erase the volume or the drive you chose, according to the options you chose. Don’t forget to backup your data first!
