   This issue might be a duplicate of existing issues. Please check:

   • TUI renders blank when project has node_modules without .gitignore exclusion #27072: Nearly identical root cause and symptoms — ENAMETOOLONG errors from file.watcher scanning large directories causing blank TUI (also filed by the same author; consider consolidating)
   • opencode TUI fails to launch with setRawMode errno 9 on macOS (web UI works) #24240: Same error signature (setRawMode failed with errno: 9, EIO: i/o error, blank TUI on macOS)
   • TUI blank screen in non-pure mode with external plugin; setRawMode failed with errno: 9 (macOS) #26217: Same setRawMode failed with errno: 9 blank screen issue on macOS

   Additional report (macOS 26.5, opencode 1.17.17)

   Hit the same blank TUI on a fresh Homebrew install (anomalyco/tap/opencode 1.17.17).

   Environment

   • OS: macOS 26.5.2 (Darwin 25.5.0, arm64)
   • Install: Homebrew (/opt/homebrew/bin/opencode)
   • Terminal: standard macOS terminal (also reproducible in non-TTY environments)

   Symptoms

   • Running opencode → blank screen, no UI, appears hung
   • opencode run and TUI mode hang at init in logs
   • opencode serve starts fine (headless works)
   • opencode models, opencode debug config work without full instance init

   ~/Library size

   • ~45 GB and ~650k files when the bug occurred
   • After cleanup (removed Android SDK, unused app data, etc.) still ~27 GB — issue was present before and after cleanup

   Logs

   Logs stop at init, then (when run with a PTY) ENAMETOOLONG: name too long, open during directory walk — consistent with file watcher / home-dir scanning blocking startup.

   Workaround (confirmed working)

   Launch with a minimal HOME and symlink real config/data paths:

   REAL_HOME="$HOME"
   MINIMAL_HOME="${TMPDIR:-/tmp}/opencode-minimal-home-${USER}"
   mkdir -p "$MINIMAL_HOME"/{.config,.local/share,.local/state,.cache}
   ln -sf "$REAL_HOME/.config/opencode" "$MINIMAL_HOME/.config/opencode"
   ln -sf "$REAL_HOME/.local/share/opencode" "$MINIMAL_HOME/.local/share/opencode"
   ln -sf "$REAL_HOME/.local/state/opencode" "$MINIMAL_HOME/.local/state/opencode"
   ln -sf "$REAL_HOME/.cache/opencode" "$MINIMAL_HOME/.cache/opencode"
   export HOME="$MINIMAL_HOME"
   exec /opt/homebrew/bin/opencode "$@"

   With this wrapper, TUI starts normally and opencode run completes successfully.

   What did NOT help

   • OPENCODE_DISABLE_DEFAULT_PLUGINS=1
   • OPENCODE_EXPERIMENTAL_DISABLE_FILEWATCHER=true
   • Clearing ~/.cache/opencode and ~/.local/share/opencode
   • --pure flag

   Happy to provide more logs or test a fix build if useful.
