macOStoUSB – Free app to create bootable macOS USB installers (Intel + Apple Silicon)

[worksdem]

Hi everyone,
I wanted to share a new app I built: macOStoUSB.

It helps you create bootable macOS USB installers with a simple guided workflow, using official Apple downloads.

What it does

• Download macOS installers (official Apple sources)
• Create bootable USB drives in a few steps
• Works on Intel and Apple Silicon Macs
• Resume support if a download is interrupted (when possible)
  

Why I made it
I wanted a cleaner, faster alternative to the usual manual process, especially for recovery, reinstalls, and preparing USB media for other Macs.

Pricing

• Free
• No account required

I’d really appreciate feedback from the MacRumors community (bugs, UX suggestions, feature ideas, anything). Thanks!

This seems a lot like https://github.com/ninxsoft/Mist

What might the advantages of this product be over Mist?

Great question — yes, there is overlap, and Mist is an excellent tool (especially for Mac admins).

Mist is very strong at listing/downloading macOS installers and generating multiple outputs (.app, .dmg, .iso, .pkg, IPSW, beta catalogs, exports, CLI workflow).

macOStoUSB is focused on a different use case: a guided “USB-first” flow for non-expert users:

• pick macOS version
• pick USB drive
• download + format + create bootable media
• verify boot markers
• resume interrupted downloads

So if you want flexibility and admin-level options, Mist is hard to beat.
If you want the shortest path to “I need a bootable USB now”, macOStoUSB is designed for that

I assume this is only for making Mac OS bootable drives?
I want to make a Linux bootable drive...

Exactly, it lets you create bootable drives for macOS, but not for Linux.

Thanks, it works fairly well. Some rough edges when building on Monterey (try pressing all the buttons and options for example and you sometimes can x your way out of the options and therefore have to quit the app) and it looks like it was made with AI. But it did work in the end. It would be nice to be able to make a bootable one on just a particular partition instead of the whole drive. Mist does have this option.
