How to Make a Bootable MacOS Mojave Thumb Drive

Posted on by

Thanks to OSXDaily for the detailed write-up.

Download MacOS Mojave from the Mac App Store

Mojave is the latest OSX/macOS to be released from Apple and it has the somewhat minor but much-anticipated Dark Mode along with other substantial features – which I will not delve into but you can read about them on the Apple Mojave page

Items Needed for Install:

  1. USB Drive (16GB or larger)
  2. MacOS Mojave Installer

It’s pretty straightforward but if you happen to be on an unsupported Mac and need to obtain the Mojave installer then there’s a slight challenge – as Mojave will only download from the App Store on compatible devices.

For unsupported Macs go to dosdude’s Mojave page and download his macOS Mojave Patcher – this will let you download the Mojave installer directly to your system.

Run the .dmg file (you may have to tweak your Security settings to allow the app to run) and tell it where to save the installer file.  You can then use the patcher tool to create your Mojave Boot Drive.

  • Just got this working very well on a late-2009 iMac 27″ (Mac 10,1) which was running High Sierra until the other night. At first I got a bunch of failed boots when the Mac didn’t see any kind of boot device available. Once I ran the (included) Post-Install Utility (duh!) to patch all the leftover tidbits the Mac boots up fine! I’m now running a dark-mode Mojave iMac! woot woot!
