Solution: The ISO likely lacks APFS drivers. Sierra 10.12.6 installs as HFS+ by default. Create a hybrid ISO with BaseSystem.dmg extracted.
The demand for macos-sierra-10.12.6-french.iso highlights an important truth: not every user wants the latest macOS. Sierra 10.12.6 remains the last version to support 32-bit apps gracefully (before High Sierra’s APFS conversion warnings) and the final version without aggressive telemetry.
For French-speaking users running legacy music production software (Pro Tools 10, Logic Pro 9), vintage scanners, or specialized industrial hardware, this ISO is a critical tool.
Final recommendation: Always build your own ISO using the method above. It is legal, safe, and ensures you get a clean French localization. If you must download, verify the SHA-256 hash against known good values and never run unknown executables.

softwareupdate --fetch-full-installer --full-installer-version 10.12.6
Note: This may fail in 2025 as Apple redirects to newer OS versions.
If you have a .dmg or .app file that is English-only, you can add French later via Language Chooser, but a true native ISO requires the French .lproj folders inside Install macOS Sierra.app/Contents/Resources/.
