Ribbontmux or a window manager on a Mac?
tmux arranges terminals inside one terminal window and keeps sessions alive when you disconnect, which matters most on remote machines. A window manager arranges every window on your Mac, terminals, browsers and editors alike. If all your work is in a terminal, tmux alone can be enough. If you mix terminals with GUI apps, you want a window manager, and many people use both.
What each one does
| tmux | Window manager | |
|---|---|---|
| Arranges | Panes inside one terminal window | Every app's windows on screen |
| Survives disconnect | Yes: detach, reattach later, even over SSH | No; it arranges, it doesn't host |
| Works over SSH | Yes, and that's its main strength | Only arranges the local terminal window |
| Mixes in GUI apps | No | Yes |
| Config | ~/.tmux.conf | Varies: a file or a settings window |
When tmux alone is enough
- You work mostly on remote servers and need sessions that survive a dropped connection.
- Your whole workflow is terminal programs: Neovim, a shell, a test runner,
htop. - You want the same layout on any machine you SSH into.
Install it with brew install tmux. The prefix is ⌃B by default; many people move it to ⌃A or ⌃Space.
When you want a window manager
- You keep a browser, docs, chat or an IDE open alongside terminals.
- You want terminals as separate Mac windows so ⌘`, Mission Control and screen sharing see them individually.
- You run several long-lived terminals locally (servers, agents, logs) and want each at a readable size. See arrange terminal windows on a Mac.
Using both
The common split of jobs:
- tmux on remote machines for persistence, often just one or two panes.
- The window manager locally for everything else, including the terminal windows that host those tmux sessions.
Two things keep them from tripping over each other:
- Different modifiers. tmux uses a ⌃-key prefix and then a plain key. A window manager on ⌃⌥ or a Hyper key never collides with it.
- Same direction keys. Bind tmux pane movement to prefix plus H/J/K/L, and use H/J/K/L with the window manager's modifier for windows. Same muscle memory, two levels.
A minimal ~/.tmux.conf for that:
set -g mouse on
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -RRibbon alongside tmux
Ribbon is a scrolling window manager whose defaults are ⌃⌥H/J/K/L for focus and ⌃⌥⇧ plus the same keys to move windows, so it sits one level above tmux's prefix-hjkl without clashing. Each terminal window gets its own column on a horizontal strip, next to your browser and editor columns; opening another terminal adds a column instead of shrinking the rest. Stacks (⌃⌥]) put two terminal windows in one column, top and bottom, which covers the "two panes" case without tmux if you're working locally. Try it in the live demo; pricing is $9.99 once.
FAQ
Do I need tmux on a Mac?
Not for local work if your terminal has splits and tabs, or you use a window manager. tmux earns its place on remote machines and for sessions that must survive disconnects.
Can tmux replace a tiling window manager?
Only for terminal programs. It can't arrange a browser or an editor that isn't running in the terminal.
Will window manager shortcuts conflict with tmux?
Not if the window manager uses a different modifier, such as ⌃⌥ or a Hyper key. tmux's prefix is a single ⌃ combination followed by a plain key.
