Anthropic Cowork feature creates 10GB VM bundle on macOS without warning

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

1. Apple‑Virtualization & Nested‑VM headaches
Users repeatedly complain that Claude’s “Cowork” feature relies on Apple’s Virtualization framework, which can’t run nested macOS guests and forces a large, opaque VM image.

“Yup it uses Apple Virtualization framework for virtualization… it caused a nested VM error.” – bachittle
“Apple’s Virtualization.Framework support for nested virtualization… only Linux guests.” – thomascountz

2. Disk‑space bloat and “System Data” mystery
The discussion is dominated by frustration over apps that silently consume gigabytes of storage, especially the 10 GB Claude VM bundle, and the lack of clear tools to locate and delete the waste.

“It’s incredible how many applications abuse disk access.” – MarleTangible
“The system data issue on macOS is awful.” – kace91
“I had the same problem and had some luck cleaning things up by enabling ‘calculate all sizes’ in Finder.” – dotxlem

3. UX / transparency problems with Claude Desktop
Users feel the product is opaque: it downloads a huge VM without warning, requires developer mode on Windows, and can silently fail or lock up.

“Claude Desktop installer requires developer mode.” – consumer451
“Claude Desktop app creates huge VM file on my disk.” – quinncom
“Claude Cowork grabs local DNS resolution… conflicts with secure web gateway.” – aberoham

4. Sandbox trust, approval fatigue, and security trade‑offs
The conversation centers on the need for a robust, user‑controllable sandbox that balances safety with usability, and the annoyance of repeated permission prompts.

“The sandboxing is necessary to balance the power you get with generating code with the security you need for non‑technical users.” – zhyder
“Approval fatigue… not having to ask for approval is valuable.” – Felix (Anthropic engineer)
“The software seems to get into more and more and communicate about what it's doing less and less.” – crumpled

These four themes capture the bulk of the discussion: virtualization limitations, disk‑space abuse, UX opacity, and the ongoing struggle to sandbox AI tools safely and transparently.

🚀 Project Ideas

DiskSpace Auditor

Summary

  • Visualizes hidden caches, system data, and app‑specific storage on macOS.
  • Provides one‑click cleanup, size thresholds, and scheduled purges.
  • Core value: eliminates “System Data” mystery and frees disk space without SIP workarounds.

Details

Key Value
Target Audience macOS developers, musicians, video editors, power users
Core Feature Tree‑map UI, hidden‑folder scanning, auto‑cleanup, size alerts
Tech Stack SwiftUI, FileManager APIs, ncdu integration, CoreData for prefs
Difficulty Medium
Monetization Revenue‑ready: $4.99/month for premium cleanup & scheduling

Notes

  • Users like “I had the same problem and had some luck cleaning up by enabling ‘calculate all sizes’ in Finder” (dotxlem).
  • “System Data” is a pain point; this tool gives a clear view and easy deletion.
  • Encourages discussion on best‑practice disk hygiene.

AI Sandbox VM Manager

Summary

  • Manages AI sandbox VMs (e.g., Claude Cowork) with configurable size, location, and cleanup.
  • Supports nested virtualization detection, external‑drive placement, and lightweight container fallback.
  • Core value: removes 10 GB hidden VM, gives users control over sandbox resources.

Details

Key Value
Target Audience AI developers, non‑technical users of Claude, SMBs
Core Feature VM bundle selector, size slider, external‑drive mounting, auto‑purge
Tech Stack Go (CLI), Electron UI, Apple Virtualization framework, Docker for containers
Difficulty Medium
Monetization Hobby

Notes

  • “I discovered the huge VM file on my disk” (quinncom) – this tool pre‑warns and offers deletion.
  • “Allow Cowork to work on directories outside the homedir” (ukuina) – solved via mount options.
  • Sparks conversation on balancing sandbox security vs. user convenience.

Seatbelt Explorer & Sandbox Toolkit

Summary

  • Exposes Apple Seatbelt APIs, provides a sandboxing framework for developers.
  • Includes permission editor, sandbox policy generator, and runtime monitor.
  • Core value: gives developers a documented, safe sandbox alternative to full VMs.

Details

Key Value
Target Audience macOS developers, security teams
Core Feature API docs, sandbox policy editor, live process monitor
Tech Stack Swift, Xcode, Swift Package Manager, Terminal CLI
Difficulty High
Monetization Revenue‑ready: $9.99/month for enterprise license

Notes

  • “Seatbelt is largely undocumented” (j16sdiz) – this fills that gap.
  • “Claude Cowork uses it, but it’s barely good for anything” (ctmnt) – provides a better alternative.
  • Enables discussion on sandboxing best practices and Apple’s security model.

Smart Cloud Sync Manager

Summary

  • Centralizes control over iCloud, Photos, Messages, Podcasts, and other cloud services.
  • Allows per‑app local‑storage limits, auto‑offload, and attachment cleanup.
  • Core value: prevents 100 GB podcast downloads and 200 GB message caches from bloating local storage.

Details

Key Value
Target Audience iOS/macOS users, photographers, podcasters
Core Feature Per‑app storage quota, auto‑offload toggle, attachment purge wizard
Tech Stack Swift, CloudKit APIs, CoreData, background fetch
Difficulty Medium
Monetization Revenue‑ready: $2.99/month for advanced quota management

Notes

  • “Apple Podcasts app decided to download 120GB of podcasts” (quinncom) – this tool stops that.
  • “I want to set a limit on how much local disk it uses” (mh‑) – directly addressed.
  • Provides a practical utility that many HN users struggle with.
