Cowork feature creates 10GB VM bundle that severely degrades performance
Summary
GitHub issue reports that Claude's cowork feature creates a 10GB VM bundle on macOS, causing slow startup, UI lag, and overall performance degradation. The VM bundle is not cleaned up and regrows after deletion; cleanup reduces size and yields temporary speedups, but degradation returns within minutes. The article documents the environment, symptoms, a workaround to delete the VM bundle and caches, and calls for reliable resource cleanup and memory leak investigation.
