Codex desktop on macOS can silently fill your disk with crash dumps; one user found 323 GB
A crash-handler loop in the Codex/ChatGPT desktop app writes about one dump per second to ~/Library/Application Support/Codex/Crashpad/pending with no pruning, and an Oct 17 report on build 26.1007 measured ~323 GB across ~4 million files. Check that folder: emptying pending/ recovers the space, though it can refill until OpenAI ships a cap.
