If reads/probes work but sends fail with AppleEvents `-1743`, check whether Automation landed on `/usr/libexec/sshd-keygen-wrapper`; see [SSH wrapper sends fail with AppleEvents -1743](/channels/imessage#ssh-wrapper-sends-fail-with-appleevents-1743).

<Accordion title="SSH wrapper sends fail with AppleEvents -1743">
A remote-SSH setup can read chats, pass `channels status --probe`, and process inbound messages while outbound sends still fail with an AppleEvents authorization error:
```text
Not authorized to send Apple events to Messages. (-1743)
```
Check the signed-in Mac user's TCC database or System Settings > Privacy & Security > Automation. If the Automation entry is recorded for `/usr/libexec/sshd-keygen-wrapper` instead of the `imsg` or local shell process, macOS may not expose a usable Messages toggle for that SSH server-side client:
```text
kTCCServiceAppleEvents | /usr/libexec/sshd-keygen-wrapper | auth_value=0 | com.apple.MobileSMS
```
In that state, repeating `tccutil reset AppleEvents` or rerunning `imsg send` through the same SSH wrapper may keep failing because the process context that needs Messages Automation is the SSH wrapper, not an app the UI can grant.
Use one of the supported `imsg` process contexts instead:
- Run the Gateway, or at least the `imsg` bridge, in the logged-in Messages user's local session.
- Start the Gateway with a LaunchAgent for that user after granting Full Disk Access and Automation from the same session.
- If you keep the two-user SSH topology, verify that a real outbound `imsg send` succeeds through the exact wrapper before enabling the channel. If it cannot be granted Automation, reconfigure to a single-user `imsg` setup instead of relying on the SSH wrapper for sends.

If the Gateway is not running on the signed-in Messages Mac, keep `channels.imessage.enabled=true` and set `channels.imessage.cliPath` to an SSH wrapper that runs `imsg "$@"` on that Mac. The default local `imsg` path is macOS-only.
Before relying on an SSH wrapper for production sends, verify an outbound `imsg send` through that exact wrapper. Some macOS TCC states assign Messages Automation to `/usr/libexec/sshd-keygen-wrapper`, which can make reads and probes work while sends fail with AppleEvents `-1743`; see [SSH wrapper sends fail with AppleEvents -1743](/channels/imessage#ssh-wrapper-sends-fail-with-appleevents-1743).
