MagSpeed adaptive scroll-wheel with SmartShift

The speed-adaptive scroll wheel shifts between two scrolling modes automatically. As you scroll faster, it will automatically shift from line-by-line scrolling to free-spinning.

• Line-by-line (ratchet) mode — ideal for precise navigation of items and lists.
• Hyper-fast (free-spin) mode — near-frictionless spinning, letting you fly through long documents and web pages.
  
  

Switch modes manually

You can also manually switch between modes by pressing the mode shift button.

By default, mode shift is assigned to the button on top of the mouse.

In Logitech Options+ software, you can decide to disable SmartShift if you prefer to stay in one scrolling mode and always shift manually. You can also adjust the SmartShift sensitivity, which will change the speed required to automatically shift into free spinning.

Horizontal Scrolling

You can scroll horizontally with your MX Anywhere 3S for Mac!
This is done with a two-button combination: Press and hold one of the side buttons and scroll with the wheel simultaneously.

NOTE: The horizontal scroll is ON by default in your Logitech Options+ software. You can customize this feature in the Point & Scroll tab in Logitech Options.

For more detailed information on Horizontal scroll, click here.

Back/Forward buttons

The back and forward buttons enhance navigation and simplify tasks.

To move back and forward:

• Press the back or forward button to navigate web or document pages, depending on the location of the mouse pointer.

NOTE: On a Mac, enabling the back/forward buttons requires the installation of Logitech Options+ software.

In addition to enabling the buttons for use with Macs, Logitech Options+ software lets you assign other useful functions to the buttons, including undo/redo, OS navigation, volume up/down, and more.

Darkfield 8000 DPI Sensor

Install Logitech Options+ software to enable the new capabilities of the Darkfield 8000 DPI Sensor.

By default, the MX Anywhere 3S has a 1000 DPI configuration.

In the Logitech Options+ Software, in the “Point and Scroll” tab, you can extend the sensor range to 8000 DPI.

Enabling this option will allow you to work faster and more precisely, allowing you to adjust the pointer speed to match high resolution monitors.

App-Specific Settings

Your mouse buttons can be assigned to perform different functions for different applications. For instance, you can assign the side buttons to control volume in Spotify, copy/paste in Microsoft Excel, or undo/redo in Adobe Photoshop.

When you install Logitech Options+, you can install predefined app-specific settings that will adapt the mouse button behavior to the selected applications.

Here are the app-specific settings we have created for you:

These settings preserve the wheel mode-shift button's functionality across all applications.

Each of these settings can be customized manually, for any application.

Adjust the feel of the scroll wheel

When you scroll in Ratchet mode, you can adjust the feel of your scroll wheel on the Point & Scroll tab in Logitech Options+.

• A lower force will make the ratchet very subtle and smooth.
• A higher force will make every ratchet very firm and precise.

Assign gestures to the top button

If you want more advanced functionality, you can assign the top button of the mouse to be the “Gesture Button”. This will transform your top button into a powerful multi-function button allowing you to use gestures for desktop navigation, app management, pan, zoom, and more.

On the Buttons tab, select the top button below the wheel and click on Gesture Button.

By default, the gesture buttons will allow you to navigate between windows and desktops.

In order to perform the gestures, you will need to hold the button while you move the mouse.

Flow between two computers

You can work on multiple computers with a single MX Anywhere 3S for Mac.

With Logitech Flow, you can use the mouse cursor to move from one computer to the next. You can even copy and paste between computers, and if you have a compatible Logitech keyboard, such as MX Keys, the keyboard will follow the mouse and switch computers at the same time.

You will need to install Logitech Options+ software on both computers and follow these instructions.

DEVICE SETTINGS BACKUP

Settings Backups

You can sign up and log into Logi Options+ to backup your device’s settings to the cloud.

Please note:

• The settings can be backed up automatically or manually
• The backups are per Logitech device per computer. This means that you can have one backup for your mouse for your home computer and one backup for the same mouse for your work computer.

• You can see and restore backups only for the OS you are currently on - Mac to Mac or Windows to Windows.
• Only device settings are backed up, not app-specific settings.

Restore backups

You can view the backups you have for a device by clicking on the Restore settings from backup button in the settings page of that device.

Please note that you can see the latest backup for your Logitech device on every computer it has been used including the current computer you are on.

Charging MX Anywhere 3S for Mac

• Connect one end of the provided charging cable to the USB-C port on the mouse and the other end to a USB power source.

A minimum of a three-minute charge gives you enough power for a full day of use. Depending on how you use the mouse, a full charge can last up to 70 days*.
* Battery life may vary depending on user and operating conditions.

Check Battery Status

The LED on the top of the mouse indicates battery status.

You can install Logitech Options+ software to receive battery status notifications, including low-charge warnings.
