What Should Happen?

Claude should not cause my macbook pro to crash due to catastrophic memory pressure

Error Messages/Logs

Steps to Reproduce

Live inspection of the affected machine: process table and Activity Monitor
process inspector for the host side; a shell inside the guest for kernel, RAM
and virtualization type; direct reads of ~/Library/Logs/Claude/{main, cowork_vm_swift}.log and ~/Library/Logs/RustDesk/. No files were modified and
no processes terminated during the investigation. All times Europe/London.
