 ### Fixes
 
+- macOS/IME input: when marked text is active, treat Return as IME candidate confirmation first in both the voice overlay composer and shared chat composer to prevent accidental sends while composing CJK text. (#25178) Thanks @bottotl.
 - macOS/Voice wake routing: default forwarded voice-wake transcripts to the `webchat` channel (instead of ambiguous `last` routing) so local voice prompts stay pinned to the control chat surface unless explicitly overridden. (#25440) Thanks @chilu18.
 - macOS/Gateway launch: prefer an available `openclaw` binary before pnpm/node runtime fallback when resolving local gateway commands, so local startup no longer fails on hosts with broken runtime discovery. (#25512) Thanks @chilu18.
 - macOS/Voice input: guard all audio-input startup paths against missing default microphones (Voice Wake, Talk Mode, Push-to-Talk, mic-level monitor, tester) to avoid launch/runtime crashes on mic-less Macs and fail gracefully until input becomes available. (#25817) Thanks @sfo2001.
