If you own a valid license for macOS (which is technically free since OS X Mavericks) AND you are installing it on Apple hardware or a virtual machine on Apple hardware, Apple’s EULA generally permits this. However, downloading pre-made ISO files from third-party file-hosting sites (Rapidgator, Mega, Torrents) is legally risky. Apple does not distribute official ISOs.

If the locale is set to English (US), these programs might crash or display character encoding errors (such as incorrect handling of "é", "ç", or "œ").

If you are an archivist, consider storing this ISO on a LTO tape or a cold-storage hard drive. For developers maintaining legacy software for the francophone market, having this ISO readily available reduces debugging time dramatically.
