Hit Yes on the pop and it will start creating the USB so it will take a considerable time. This could come in handy for many situations, be it to make boot media, or to run Catalina on various Macs (supported or otherwise). Or, if you don’t have a reliable internet connection to download the update directly. A macOS installer in DMG format could prove to be quite useful if your Mac isn’t booting up and you’re attempting recovery.

Updates to the way OSX works means that when you open Mu for the first time you need to tell your operating system that you trust the application. The simple solution is to CTRL-click the Mu application in your 'Applications' folder and then select 'Open'. If you don't you'll just see a warning pop-up (shown in the video at the top of this page).

If you're running Catalina then you might have to give the app permission to access USB mounted devices. To do that:

  • Launch System Preferences.
  • Select 'Security & Privacy'.
  • Select the 'Privacy' tab at the top.
  • In the left column select 'Full Disk Access'.
  • Then, on the right side, click the box next to mu-editor to give it permission.
  • If those options are grayed out, you need to select the padlock in the lower left of the dialog box and enter you system password before you can chance the settings.
  • Next time you launch Mu you will be able to just double click the Mu icon.
