What is new in muxbar 0.3.2
## Fix - **Closed-lid mode 자동 해제(timer / AC 분리 / lid 열림)가 비밀번호 dialog 에 막히지 않습니다.** 이전엔 타이머 만료 시 admin password prompt 가 떠서 cancel 하면 모드가 그대로 유지됐는데 (타이머 의미 무색), 이제 자동 해제는 `sudo -n pmset` 으로 silent 시도만 합니다. NOPASSWD 룰이 있으면 정상 복원, 없으면 caffeinate 세션을 정리하고 state 를 OFF 로 둔 뒤 "메뉴에서 OFF 토글로 pmset 복원 다시 시도" 알림을 발송합니다. **"N분 뒤 자동 종료" 약속이 비밀번호 입력 없이도 무조건 지켜집니다.** - 수동 OFF 의 password cancel 동작(state ON 유지 + AC/lid monitor 재무장)은 그대로입니다. ## Docs - README/README.ko: Closed-lid mode 를 **헤드리스 클램쉘**(외부 디스플레이 없이 동작하는 clamshell) 로 명시. macOS 정식 클램쉘 모드와의 비교 표 보강. ## Install ```bash brew install --cask 1989v/tap/muxbar ``` 또는 아래 `muxbar-0.3.2.dmg` 다운로드 → 우클릭 → 열기 (ad-hoc 서명).
