SSH fail due to detach error on macOS

[TTstone]

Summary

Remote proxy fails to launch due to detach error on macOS when add a SSH connection。

Description

Attempting to use Zed remote via SSH on macOS (Apple Silicon) fails during the proxy launch phase, due to an error when detaching the zed-remote-server process. This renders remote editing unusable via the proxy mechanism.

Tested with zed-remote-server-stable-0.187.8.

Steps to reproduce:
1.On macOS (M2 chip, macOS 15), install and extract zed-remote-server-stable-0.187.8 on the remote machine.
2.Confirm remote is reachable via SSH and manually executable:
ssh nauqeix@remote-host ~/.zed_server/zed-remote-server-stable-0.187.8 version
This runs fine.
3.Try to launch the proxy manually:
~/.zed_server/zed-remote-server-stable-0.187.8 proxy --identifier setup-1
4.Observe immediate failure
{"level":1,"module_path":"remote_server","file":"crates/remote_server/src/main.rs","line":105,"message":"(remote proxy) exiting due to error: failed to launch and detach server process"}

Expected Behavior:
The proxy command should start in the background successfully, allowing Zed desktop client to connect remotely.

Actual Behavior:
The proxy process crashes immediately with a detach error, making the remote connection unusable. There is no --no-detach or --foreground mode available to help debug or work around this.

log：
2025-05-27T12:27:17+08:00 INFO [remote_server::unix] (remote proxy) starting proxy process. PID: 27460 2025-05-27T12:27:17+08:00 ERROR [remote_server] (remote proxy) exiting due to error: failed to launch and detach server process

The setting is basically default and I can connect to another remote Mac but fail with this one.

Can you provide any additional info about the remote where this fails?

• Architecture
• macOS version
• shell
• etc

If you create a new clean user on the failing remote, can you connect that user successfully? Or does that also fail.

Below is the basic info:

• macOS Version: 14.5 (Build 23F79)
• Architecture: arm64 (Apple Silicon)
• Default Shell: /bin/zsh
• ssh via terminal and also cursor remote both worked on this machine.

Yes, a new clean user will work similar with another machine. But It will be great if there is a way to find the reason for such a failure.
