OpenAI Codex Desktop App Causes Persistent System Lag and SSD Wear on macOS
Mac users are reporting that the OpenAI Codex desktop application causes persistent system lag that remains even after closing the app, alongside ongoing excessive SSD write issues. This follows a previous bug where the app wrote massive amounts of diagnostic logs, threatening SSD lifespans. Excessive SSD writes can permanently damage soldered storage on modern MacBooks, which cannot be replaced by users. Additionally, the persistent lag disrupts developer workflows, requiring a full system reboot to resolve. The lag is linked to macOS's security daemon syspolicyd spiking to 200% CPU and 8GB RAM usage due to Codex's verification behavior. Although OpenAI released version 0.142.0 to reduce log writing by 85%, users still report high write speeds of 207 MB per minute on idle M4 MacBooks.
## BACKGROUND
OpenAI Codex is an AI-driven coding agent designed to automate software engineering tasks. The application's logging system previously ran at the highly detailed TRACE level, ignoring the standard RUST_LOG environment variable configuration and writing massive amounts of data to a local SQLite database.
