A GitHub repository called RemoveMacAI provides a script to disable Apple Intelligence on macOS 27 and recover the associated storage. The project first appeared in an Hacker News thread that reached 308 points and 194 comments.
What It Is
RemoveMacAI is a command-line tool that targets the system components installed by Apple Intelligence. It removes the on-device models and related services without requiring a full macOS reinstall. Users run the script once, after which the features stay disabled until manually re-enabled.
How to Try It
Clone the repository and execute the main script with administrator privileges. The process takes under five minutes on most machines and requires no additional dependencies beyond standard macOS tools. A reboot completes the removal and frees the occupied space.
"Installation commands"
git clone https://github.com/omlahore/RemoveMacAI
cd RemoveMacAI
sudo ./remove.sh
Disk Space Recovery
Early reports in the HN thread indicate reclaimed space between 4 GB and 7 GB depending on the Mac model and prior downloads. The largest single item removed is the 2.8 GB on-device language model bundle. No performance impact on other system functions has been noted by testers.
Pros and Cons
- Removes unused AI models that many users never activate
- Reversible through standard macOS update mechanisms
- Requires terminal access and basic comfort with scripts
- No official Apple support or warranty coverage stated
Alternatives and Comparisons
| Method | Space Freed | Reversibility | Skill Level |
|---|---|---|---|
| RemoveMacAI script | 4-7 GB | High | Terminal |
| macOS Storage settings | 0-2 GB | High | GUI |
| Clean install of macOS | 6-10 GB | Low | Advanced |
Other manual approaches through System Settings recover less space and leave background services intact.
Who Should Use This
Power users on macOS 27 who never invoke Apple Intelligence features gain the most. Teams managing shared devices or users on smaller SSDs benefit from the immediate storage increase. Skip the tool if you rely on Writing Tools, Image Playground, or Siri enhancements that depend on the on-device models.
Bottom Line
RemoveMacAI delivers a targeted, reversible way to eliminate Apple Intelligence storage overhead on macOS 27 with minimal effort. The HN discussion confirms consistent results across multiple hardware configurations.
