Can’t run uv sync in the sandbox due to file system access block #1300

Describe the bug

When I try to run uv sync in a sandboxed environment, the command fails due to blocked file system access. The sandbox prevents the command from accessing the required cache directory, resulting in an error. See the attached screenshot for details.

Affected version

No response

Steps to reproduce the behavior

1. Open a sandboxed terminal environment.
2. Run the command: uv sync
3. Observe the error indicating failure to access the required cache directory.

Expected behavior

uv sync should be able to run successfully in the sandbox, or provide a clear message if file system access is not permitted.

Additional context

Terminal output indicates: "failed to open file... os error 1".

System: macOS using a sandboxed environment.
