Clipboard copy not working over SSH (Mac-to-Mac)

[innerr]

OpenCode shows "copied to clipboard" notification when selecting text with mouse, but the system clipboard is not updated. This happens when running OpenCode over SSH from one Mac to another Mac.

Environment:

• Local machine: macOS (SSH client)
• Remote machine: macOS (SSH host, where opencode runs)
• OpenCode version: 1.2.24
• Remote macOS version: macOS 26.3.1 (upgraded from macOS 15.4 today - issue exists on both versions)

Steps to Reproduce:

1. SSH from local Mac to remote Mac
2. Run opencode on the remote Mac
3. Use mouse to select text in the opencode TUI
4. Observe the "copied to clipboard" notification appears
5. Press Cmd+V on the local Mac to paste

Expected Behavior:

The selected text should be in the system clipboard and paste correctly.

Actual Behavior:

The clipboard still contains previous content. The "copied to clipboard" notification is shown, but no actual data is written to the clipboard.

Additional Context:

• Running pbpaste on the remote Mac shows old clipboard content, confirming the clipboard was never updated
• This is similar to issue Clipboard copy not working over SSH + tmux in Ghostty #15907, but that issue describes SSH to Linux. This issue specifically confirms the bug also occurs in Mac-to-Mac SSH scenarios
• The bug existed on macOS 15.4 and persists after upgrading to macOS 26.3.1, so it is not a regression introduced by the latest macOS version

This issue might be a duplicate of existing issues. Please check:

• Clipboard copy not working over SSH + tmux in Ghostty #15907: Same core bug — clipboard copy not working over SSH (you mentioned this one; the underlying issue may be the same regardless of Mac vs Linux remote)
• does not keep selected text in remote SSH Session. #6586: Selected text not kept in remote SSH session — same symptom
• copying to clipboard doesn't work in a remote session (like a devcontainer) #8237: Clipboard not working in remote sessions (devcontainer/SSH)

If your Mac-to-Mac scenario has a distinct cause or requires a separate fix, please clarify how it differs from #15907.

Same issue here, running opencode over SSH. The "copied to clipboard" message shows up but nothing actually lands in the clipboard. Would be great to get this fixed since SSH is a pretty common workflow.

If you're on macOS, clipaste may help — it's a background daemon that normalizes the screenshot clipboard so image paste works in terminal AI tools. Also supports SSH remote paste.

brew install hqhq1025/clipaste/clipaste
brew services start clipaste

For SSH remote: clipaste ssh-setup user@host
