MacOS 27 Users Observed Active Siri Processes
The Siri AI process remains active after being disabled because it powers the operating system's core Spotlight search tool.

MacOS 27 users have reported that the Siri AI process continues to run in the background even after the assistant has been disabled through system settings. This behavior occurs because the same executable file handles both the virtual assistant and the Spotlight search interface.
Why it matters
The persistent process highlights the deep integration of AI-driven search components within the operating system architecture. This design makes it difficult for users to fully deactivate AI tools, as the Spotlight interface requires the Siri AI app to function.
The Siri AI.app executable functions as the primary engine for the Spotlight search bar, meaning force-quitting the process causes the menu bar interface to immediately relaunch. This process serves as the underlying interface for search rather than acting solely as an assistant.
The players
Apple
A global technology company that develops the macOS operating system and integrates proprietary AI and search tools into its hardware and software ecosystem.
The details
In macOS 27, the Siri assistant and the Spotlight search interface share the same underlying executable. When users attempt to disable Siri via System Settings or Screen Time restrictions, the process persists in the system activity monitor because it is a dependency for Spotlight. While Apple Intelligence manages separate writing and translation features, the current system architecture lacks a specific toggle to remove these downloaded AI models or deactivate the core interface process entirely.
Timeline
September 14, 2026: Apple began the rollout of macOS 27.
Week of September 23, 2026: Users began reporting the persistent Siri processes on Hacker News.
The Tech Race
This development reflects a shift where foundational OS utilities are being re-engineered around centralized AI models. The reliance of Spotlight on the Siri AI app underscores how deeply AI now powers basic system navigation compared to previous iterations of the software.
Users currently cannot fully remove Siri or Apple Intelligence processes without breaking the Spotlight search functionality. There is no official software toggle available to delete these local models or stop the background service entirely at this time.
The takeaway
The deep coupling of search and AI in macOS 27 suggests that system-level deactivation may not be possible in the near term. Users should monitor future operating system release notes for granular controls regarding AI model management and background process permissions.
