finish_installation
finish_installation is a helper component of the Sparkle framework, Apple's widely-used open-source automatic software update system for macOS. The Sparkle framework handles download, verification, and installation of app updates, and finish_installation is an auxiliary tool that completes the final stages of that update process, running with elevated privileges to replace or modify application files. Users do not interact with finish_installation directly — it operates behind the scenes when an app using Sparkle applies an update.
AI Recommendation
1 suggestionfinish_installation is not a standalone application you use — it is a helper component bundled with the Sparkle update framework that ships as part of other macOS apps. You do not need to update or manage it separately. When you update any Sparkle-based app (such as VLC, Transmit, Squash, or thousands of others), that app's installer automatically includes the current native Apple Silicon version of Sparkle, which means finish_installation gets updated alongside it. If you have installed Sparkle-based apps on your Mac, simply keep those apps up to date through their normal update mechanisms — that is what ensures finish_installation itself is current and native to your architecture.
