Official Path: Download the installer from the Apple Support page for legacy macOS versions.
Manual Conversion: If you have the .app or .dmg installer, you can create your own ISO using the Terminal: Create a blank disk image. Attach the installer. Use the createinstallmedia command. Convert the resulting .cdr to .iso. 4. Installation Steps
Backup Data: Always use Time Machine to back up your current system.
Create Bootable Media: Use a USB drive (16GB+) and the createinstallmedia tool via Terminal.
Boot from USB: Restart your Mac and hold the Option (⌥) key to select the installer.
Language Selection: During the initial boot, ensure you select Français as the main language if the ISO hasn't pre-configured it.
Disk Utility: Format your target drive as Mac OS Extended (Journaled) with a GUID Partition Map. 5. Post-Installation Tips
Updates: Run Software Update to ensure all final security patches for 10.12.6 are applied.
Legacy Support: Note that many modern browsers (like Chrome) and apps no longer support Sierra. Consider using Legacy Patcher if you are trying to run newer software on this older OS.
