RemoveMacAI Tool Disables Apple Intelligence and Deletes On-Device Models on macOS 27

Tool Functionality

RemoveMacAI is an open-source command-line interface (CLI) tool designed for macOS 27 on Apple silicon. It addresses the lack of a single system switch to disable Apple Intelligence and the persistence of downloaded models on disk even after features are turned off. The tool disables specific AI features, removes the associated foundation models, and prevents macOS from downloading them again. All changes are fully reversible.

Technical Implementation

The tool operates without modifying files under /System or disabling System Integrity Protection (SIP). Instead, it uses two primary mechanisms:

• Configuration Profile: Applies Apple's restriction keys for Apple Intelligence and forces settings that lack native restriction keys.
• Download Blocking: Redirects the download requests for AI models through Apple's asset management system to a null endpoint, preventing the models from being re-downloaded.

The tool makes no network calls and collects no data. It requires macOS 27; it does not support macOS 26 or earlier.

Scope of Changes

Disabled Features:

• Siri (including "Hey Siri")
• Apple Intelligence writing tools
• Image Playground
• Genmoji
• ChatGPT integration
• Notification summaries
• Mail summaries
• Photos Clean Up
• Spatial Photos
• Xcode AI features

Removed Models:

• Foundation models used for text generation, summarization, and image processing.
• Note: Dictation models are not removed, as they are distinct from Apple Intelligence models.

Installation and Usage

The tool is distributed as a Swift package and can be installed via a shell script or Homebrew.
