OpenCore Legacy Patcher is a trusted tool that can download macOS Sequoia and create bootable USBs – works on Windows too.

It allows you to both download macOS Sequoia and build a bootable installation drive in one go, making it a flexible cross-platform solution.

First, download the software from its official website and run it

Follow the main interface until you reach the "Create macOS Installer" option, then select macOS Sequoia version. The tool will automatically download the official installer files and create a bootable USB drive.

Once the download and creation process is complete, you can use the USB drive to install macOS Sequoia on your supported Mac.

This method works on both Mac and Windows systems, so it is suitable for users who need to prepare installation media without a working Mac or App Store access.

If you don’t want to rely solely on the App Store or need to create a bootable drive on Windows, you can try this method. It is a powerful third-party tool, so you should always download it from the official source to avoid security risks.
