Article in English: To install a modern macOS/OSX operating system, you will want a flash drive with at least 16GB capacity. USB 2.0 will work, but the greater speed of USB 3.0 is highly preferable. 32GB or greater is recommended if you want to fit anything beyond the operating system on the drive.

A progress bar will appear indicating the formatting and partitioning progress. This process may take a few minutes. When complete, the progress bar will disappear.
