Monolingual

Monolingual is a macOS utility that removes unnecessary language localizations and associated resources from installed applications, reducing their disk footprint. It allows users to select which language files to keep and strips out all others from the application bundles, freeing up storage space — sometimes significantly on systems with many large apps. Power users and administrators working with storage-constrained Macs appreciate this tool for its granular control, though it requires careful use since modifying app bundles can have unintended consequences.
