opencode TUI fails to launch with setRawMode errno 9 on macOS (web UI works) #24240
Description
Description
opencode v1.14.24 installed via Homebrew on macOS (Darwin 25.3.0, zsh) launches to a blank screen when run as opencode (TUI mode). The process starts but never renders the interface and does not respond to input.
Environment
opencode 1.14.24 (/opt/homebrew/bin/opencode)
macOS Darwin 25.3.0, zsh
Reproduced in both IDE integrated terminal and macOS Terminal.app
Steps tried
opencode --version / --help → both work correctly
opencode --print-logs --log-level DEBUG → blank screen
opencode --pure --print-logs --log-level DEBUG → blank screen (DB migration completed successfully on this run)
Cleared ~/.local/share/opencode and /.cache/opencode → no change/opencode.log)
Tried in native Terminal.app (not IDE terminal) → still blank
Log output (
INFO service=server-proxy version=1.14.24 args=["--print-logs","--log-level","DEBUG"] opencode
ERROR service=server-proxy e=setRawMode failed with errno: 9 exception
ERROR service=server-proxy error=setRawMode failed with errno: 9 process error
ERROR service=server-proxy e=EIO: i/o error, read exception
Workaround
opencode web launches successfully and is fully functional, so the issue is isolated to the TUI's TTY/raw-mode initialization.
Expected
TUI renders and accepts input.
Actual
Blank screen, no input response, setRawMode fails with errno 9 (EBADF).

I think is related to #24358 or at least I have the same problem with Ghostty
