Opening preferences

There are multiple ways to open the Particulars preferences window.

Hide dock icon

Enabling this removes Particulars from the macOS Dock. This setting is often combined with Launch at login, so that Particulars runs as a background app. Enabling and disabling this preference will automatically restart Particulars to make the change effective immediately.

When enabled, relaunch the application or use the menu bar item to open the preferences window.

Show Particulars in menu bar

Adds a Particulars item to the macOS menu bar which allows quick access to preferences, copying, and other functions.

Theme tab

Text theme

Particulars has 3 built-in themes: Default, System, and Mono. The Default theme uses the Lato font. The System theme uses the current system font. (Current versions of macOS use the San Francisco font.) The Mono theme uses a monospaced font. Mono will use Menlo or SF-Mono, if installed.

Alternatively, a custom theme can be used. The Custom theme gives full control over the font, size, color, and opacity of the system information on the desktop.

In all cases, if a font fails to load, Particulars defaults to the Default theme.

Text shade

Text shade can be set to Auto, Light, or Dark. In Auto mode, the desktop background image is analyzed and the mode is chosen based on the color content of the background. Auto mode will reanalyze the background if you change it or switch to another space. (If Auto mode encounters problems loading or analyzing your background image, it defaults to Light.)

(When using a Custom theme, the Text shade option is hidden and Auto mode is disabled.)

Text size

Sets the text size to any value between 12 and 24 pt.

(The Text size option is hidden when using a Custom theme.)

Label case

Sets the case of letters in labels. It can be Unaltered, lower or UPPER case.

This preference is also available in the Today Extension (Widget).

Drop shadow

Turns drop shadow on or off.
