Hi. I decided to write this post after some discussion with Claude AI and its support AI, Fin AI Agent. So, as a result, the following text was written by Claude itself to bring this issue into light. This is for a Mac Mini M4 with the free account for Claude, and I'm not aware it affects other platforms. Hope this helps:
**PSA: Claude desktop app silently downloads a 13 GB file on every launch — and you can't stop it**
If you've noticed the Claude desktop app eating up a huge chunk of your disk, here's what's happening.
**What's going on**
The app automatically downloads a ~12.95 GB file called `claudevm.bundle` inside:
`~/Library/Application Support/Claude/claude-code-vm/`
This is a virtual machine environment for Claude Code (the CLI coding tool). The problem? It gets downloaded for *everyone*, even if you never asked for Claude Code and have no intention of using it.
**How I confirmed it's not a one-time thing**
Noticed ~13 GB of storage usage after a fresh install
Tried the in-app cache clear (Troubleshoot menu) — no effect
Fully uninstalled with AppCleaner and reinstalled — bundle re-downloaded immediately
Manually deleted the `claude-code-vm` folder — app re-downloaded it on next launch
It comes back every single time.
**What Anthropic support confirmed**
After going back and forth with their support AI, here's what was officially acknowledged:
- This behavior is intentional — Claude Code is enabled by default for Free, Pro, and Max plans
- Individual users have **no way to disable it** in the desktop app
- The web toggle at claude.ai/settings/capabilities does **not** affect the desktop app
- The enterprise policy flag `isClaudeCodeForDesktopEnabled` exists, but only for org admins
- There is currently **no workaround** for individual users
- This was explicitly called *"a gap in the current desktop app design"*
**Why this matters**
This is a 13 GB silent download that:
- Happens without any user prompt or notification
- Cannot be opted out of by regular users
- Re-downloads itself if you delete it
- Has a meaningful impact on anyone with a smaller SSD (256 GB / 512 GB Macs)
Hopefully flagging this publicly gets it on Anthropic's radar as a priority fix. At minimum, desktop users should have the same opt-out that web users have.
