Mux Manager for Mac

Your SSH hosts and tmux windows in a native Mac app. Read colored output in Smart, preserve the remote grid in Original, or explicitly resize with Fit window.

Developer ID signed and notarized by Apple. Universal app for Apple Silicon and Intel. This download is distributed directly, outside the Mac App Store.

Install

1. Download and unzip MuxManager-macOS.zip.
2. Move Mux Manager.app to Applications and open it. Connect to the internet for the first launch so macOS can verify notarization.
3. Sign in to the same Apple Account with iCloud Keychain enabled to receive saved hosts and credentials from your iPhone or iPad.

Uses the same bundle identifier and Production CloudKit container as the iPhone/iPad download. Sync is automatic. A host still needs SSH and tmux 3.2 or later; nothing extra is installed remotely.

New in build 18

• A built-in This Mac connection opens local tmux and your shell without SSH or saved credentials. It stays on the Mac and never enters iCloud or Keychain. Install tmux 3.2 or later locally.
• Solid cursors in Smart, Original, and Fit, with no pulsing. Smart now preserves the cursor at empty shell prompts and when Live is paused.
• Prompt refreshes after typing, fewer round trips for queued keys on slow links, and a wider Add Connection dialog.
• Fixed the local MuxCore package reference for building from Xcode.

Local commands run with your Mac user’s permissions, subject to macOS privacy controls.

Native Mac controls

• Terminal-only input: Return, Tab, arrows, and Shift-Tab go directly to the remote shell or TUI. There is no Compose box or Send button.
• Terminal: direct typing, Shift-Tab, Command-C and Command-V. Mouse input selects and scrolls locally.
• Command-N adds a connection; Shift-Command-L follows Live; Shift-Command-T focuses Terminal.
• Terminal input stays literal. Click unselected Smart output or use Focus terminal to resume typing after selecting text.

Keep an eye on Codex

Enable Info → Codex notifications to receive best-effort local alerts naming the host and window. Connections and eligible checks continue while another app is active. They cannot run while your Mac sleeps. Checks pause after 2 minutes idle or 30 minutes since the window was opened or used; revisit it or send input to resume.
