Compatibility & requirements

In order to make this custom bar work, you'll need to install both yabai and Übersicht, both of them must be up to date.

Becareful, for Big Sur users, some actions must be taken in order to make yabai fully operational: see here for more details.

simple-bar has been tested and is working on both Catalina & Big Sur. You'll need a screen with a size of 13" at least and with your screen resolution scaled on "More space" setting.

It is important to note that you'll need to use yabai in bsp or stack layout mode in order to prevent app windows to overlap simple-bar.

On the first simple-bar execution, an alert should pop on your screen saying that Übersicht want access your browser control (only the first time you launch your favorite browser with simple-bar opened). It is required to agree to this in order to make the CurrentTrack widget work.



You'll find more information & images on simple-bar website.


Clone this repo to your Übersicht widgets directory with the following command.

$ git clone https://github.com/Jean-Tinland/simple-bar $HOME/Library/Application\ Support/Übersicht/widgets/simple-bar

Becareful, the folder containing the widget must be name simple-bar, otherwise, simple-bar will never launch.

JetBrains Mono is used by default. You can set your own font in the "Global" settings tab.

For users with a custom yabai install (path)

There is a setting in the settings module allowing a custom yabai path.


After cloning the project, simply activate both simple-bar widgets in Übersicht's widgets list.

  • simple-bar-data-jsx
  • simple-bar-spaces-jsx


As explained at the begining of this README file, Settings can be opened by pressing cmd + , after cliking on simple-bar widget. You may want to click at the top center of the screen, where the process name of the current app is displayed in order to easily get focus on simple-bar before pressing cmd + ,.

In this settings module you'll find all the customization options available from layout to specific widgets show/hide toggle.

Clickable elements

Some elements of simple-bar are interactives. For example :

  • Toggle caffeinate mode on battery widget click (prevent your mac to sleep while activate)
  • Toggle wifi on/off on wifi widget click
  • Toggle microphone on microphone widget click
  • Play/pause Spotify or Music-iTunes current song on Spotify/Music-iTunes widget click
  • Open Calendar app on date widget click
  • Open weather previsions in browser on weather widget click
  • Remove, move spaces on space hover (1s delay / instant while cmd key is pressed) (Only with SIP disabled)
  • Add space on "plus" button click (Only with SIP disabled)

Clickable elements have an outline showing up on hover in order to easily identify them.


Colors & theme

If you want to customize the colors, shadows, fonts, etc... you can simply tweak and existing theme or create your own in simple-bar > lib > styles > themes.

You can duplicate an existing theme and change the exported function name, the "name" and the "kind" (light or dark) properties.

Once you created your theme, you can import it in simple-bar > lib > styles > themes > themes.js and add it in the already exported themes. You theme should now appear in the "Themes" settings tab.

Feel free to open an issue if you want me to add a theme or if you created a theme and are willing to share it.


To use pywal colors instead, run the pywal-gen.sh script in simple-bar > lib > styles > pywal, then edit simple-bar > lib > styles > theme.js : const WITH_PYWAL = false must be set to "true".
This should be done after running pywal.
As I am not using this myself, I may have missed some problems, feel free to open an issue about it anytime.


Now to add new icons you'll need to get a .svg with a 0 0 24 24 viewBox. Then you can simply add it to the simple-bar > lib > components > Icons.jsx:

export const Caprine = (props) => (
  <Icon {...props}>
    <path d="M12 0C5.37 0 0 4.97 0 11.11c0 3.5 1.74 6.62 4.47 8.65V24l4.09-2.24c1.09.3 2.24.46 3.44.46 6.63 0 12-4.97 12-11.1C24 4.97 18.63 0 12 0zm1.2 14.96l-3.06-3.26-5.97 3.26L10.73 8l3.13 3.26L19.76 8l-6.57 6.96z" />

To link it to a process you'll need to get the Yabai process name and make the association in simple-bar > lib > app-icons.js :

import as * Icons from './components/Icons.jsx'

export const appIcons = {
  'Android Messages': Icons.AndroidMessages,
  Caprine: Icons.Caprine,
  Code: Icons.Code,
  Default: Icons.Default,
  Figma: Icons.Figma,
  'Google Chrome': Icons.GoogleChrome,
  Music: Icons.Music,
  'Sequel Pro': Icons.SequelPro,
  Skype: Icons.Skype,
  Slack: Icons.Slack,
  Zeplin: Icons.Zeplin

If there is no icon defined for a running process, there is a default one which will be used as fallback.

Same as for themes, feel free to open an issue if you have an icon request.

Override default styles

As I tried to automate a lot of things, there may be some elements impossible to specificaly change by creating your own theme.

To remedy this problem, there is a tab in settings allowing you to override any simple-bar style you want.

You can simply add your styles here. As it is loaded after all the other styles this will naturally override the default styles.
You can use the Übersicht debug console in order to inspect the widgets composing simple-bar and get the class names you need to override.
