● USB receiver: Plug the receiver into a USB port, open Logitech Options, and select: Add devices > Setup Unifying device, then follow the instructions.
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 Scroll
You can scroll horizontally with your MX Anywhere 3!
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 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
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:
| 1 | 2 | ||
| Default settings | Middle Button | Back | Forward |
| Browser (Chrome, Edge, Safari) | Open link in a new tab | Back | Forward |
| Zoom | Middle Button | Mute / Unmute Microphone | Start/Stop Video |
| Microsoft Excel | Pan (Hold and move the mouse) |
Undo | Redo |
| Microsoft Word | Pan (Hold and move the mouse) |
Undo | Redo |
| Microsoft PowerPoint | Pan (Hold and move the mouse) |
Undo | Redo |
| Adobe Photoshop | Pan (Hold and move the mouse) |
Undo | Redo |
| Adobe Premiere Pro | Pan (Hold and move the mouse) |
Undo | Redo |
| Apple Final Cut Pro | Pan (Hold and move the mouse) |
Undo | Redo |
With these settings, the wheel mode-shift button retains the same 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 Mouse 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 3.
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.
Charging MX Anywhere 3
- 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.

Gaming mouse compatibility with Logitech Unifying receivers
The Logitech G403 Wireless, G304, G305, G603, G703, G903 are built on the LIGHTSPEED architecture and connect to proprietary LIGHTSPEED receivers. They are not compatible and cannot be paired with the Unifying receiver.
Connectivity range of the Unifying receiver
The connectivity range for your mouse is 10 meters (33 feet) from the Unifying receiver. Moving the mouse closer will improve connectivity.
Operating distance between the mouse or keyboard and USB receiver
In an ideal environment, a Unifying or non-Unifying device can operate up to 30 feet (10 meters) away from its receiver (shown below) in a clear line of sight.
If you’re not getting this distance, try these suggestions:
Replace the battery/batteries or make sure your mouse or keyboard is fully charged
Move devices that emit radio waves or could cause radio interference away from your work area (Examples: cell phones, radios, wireless routers, microwaves)
To determine if your environment is shortening your operating range, try using your device in a different environment to see if the distance improves. If it does, look for other possible sources of interference you can remove from your work area.
USB receiver storage
Most Logitech mice are designed with a space to store its receiver. When you’re not using the mouse, you can store the receiver inside of it.
To locate the storage space for the receiver in your mouse:
1. Flip the mouse over and slide the battery cover off.
2. Locate the small rectangular slot next to the battery compartment.
3. Slide the receiver into the slot. It will fit facing either way.
4. Replace the battery cover.
Note: The image is only for reference to indicate the location of the receiver. The actual receiver may look different depending on the product specification.
TIP: If you have an extra receiver from any Logitech device you aren’t currently using, this is a great place to store it.

My Unifying mouse or keyboard wakes the computer even when it is set not to…..
Symptom
After disabling the ability to wake-up the system in Windows Device Manager, the Unifying mouse or keyboard still brings the system out of sleep mode.
Solution
Even if you bought a mouse-only or keyboard-only product, the Unifying receiver that came with it still enumerates for both the mouse and keyboard interfaces.
Example
If you have two mice attached, then you would need to uncheck the “Allow this device to wake the computer” option for both mice plus a keyboard in the Windows Device Manager.
Use the process below to identify and configure the Unifying devices to not wake up the system in Windows Device Manager.

How to enable Accessibility and Input monitoring permissions for Logitech Options
We’ve identified a few cases where devices aren’t detected in the Logitech Options software or where the device fails to recognize customizations made in the Options software (however, the devices do work in out-of-box mode with no customizations).
Most of the time this happens when macOS is upgraded from Mojave to Catalina/BigSur or when interim versions of macOS are released. To resolve the problem, you can enable permissions manually. Please follow the steps below to remove the existing permissions and then add the permissions. You should then restart the system to allow the changes to take effect.
Remove existing permissions

2. Go to System Preferences -> Security & Privacy. Click the Privacy tab, and then click Accessibility.
3. Uncheck Logi Options and Logi Options Daemon.
4. Click on Logi Options and then click on the minus sign ‘–’ .
5. Click on Logi Options Daemon and then click on the minus sign ‘–’ .
6. Click on Input Monitoring.
7. Uncheck Logi Options and Logi Options Daemon.
8. Click on Logi Options and then click on the minus sign ‘–’.
9. Click on Logi Options Daemon and then click on the minus sign ‘–’.
10. Click Quit and Reopen.
Add the permissions
To add the permissions:
Go to System Preferences > Security & Privacy. Click the Privacy tab and then click Accessibility.
Open Finder and click on Applications or press Shift+Cmd+A from the desktop to open Applications on Finder.

Click Quit and Reopen.
Restart the system.
Launch the Options software and then customize your device.
Can I switch my mouse and keyboard at the same time using one Easy-Switch button?
It is not possible to use one Easy-Switch button to at the same time change both your mouse and keyboard to a different computer/device.
We do understand that this is a feature that a lot of customers would like. If you are switching between Apple macOS and/or Microsoft Windows computers, we offer Flow. Flow allows you to control multiple computers with a Flow-enabled mouse. Flow automatically switches between computers by moving your cursor to the edge of the screen, and the keyboard follows.
In other cases where Flow is not applicable, one Easy-Switch button for both mouse and keyboard might look like a simple answer. However, we cannot guarantee this solution at the moment, as it is not easy to implement.
Adobe Photoshop 22.3 incompatibility with Mac M1 computers and Logitech Options

1. Install the latest Logitech Options software.
2. Install Adobe Photoshop 22.3.
3. Connect any plugin-supported device.
4. Navigate to Applications > Adobe Photoshop 2021 > Adobe Photoshop 2021.
5. Right-click on Photoshop.

MX Anywhere 3 wheel makes a ticking noise when switching between applications
If you have different wheel force settings for Chrome versus All Applications or Excel, then you will hear the wheel reset the force every time you go from one app to the next. This happens when you have enabled the App-specific settings for the Point & Scroll tab for a specific app.
To remove the noise, disable Application specific settings and restore the defaults.
Wheel noise when scrolling with MX Anywhere 3
The MX Anywhere 3 MagSpeed wheel should be very quiet. But when you scroll in ratchet mode, it’s possible that your wheel generates a little bit of noise. An easy way to reduce the noise is to reduce the wheel scrolling force. Note that increasing the scrolling force will also increase the noise.
Move the Scroll force slider to the left to reduce the scrolling force.
Adjust scrolling force on the MX Anywhere 3 mouse
When you scroll in Ratchet mode, you can adjust the scroll feel of your wheel by moving the Scroll force slider on the Point & Scroll tab.
A lower force will make the ratchet very subtle and smooth.
A higher force will make every ratchet very firm and precise.
What is SmartShift on MX Anywhere 3?
When your wheel is set on Ratchet mode (you can feel each line when you scroll), enabling smart-shift lets you switch to free wheel mode automatically as you scroll faster. Without SmartShift, you would need to press on the Mode Switch button on top of of the mouse:
When SmartShift is enabled if you start scrolling faster while in Ratchet mode, your wheel automatically switches to free wheel mode (frictionless scrolling).

How does Horizontal Scroll work?
To scroll horizontally:
On the left side of the mouse, press and hold the backward or forward button.
Start scrolling the main wheel.
A short press on the back/forward buttons will still allow you to perform the back / forward actions (the command is only sent when you release the button).
NOTE: Some advanced features that require a long-press on the side buttons will not be compatible with the horizontal function. For example, if you assign the back or forward buttons to Gesture button, Advanced click, Change pointer speed, or Modifiers, it will automatically disable the horizontal scroll function on the button. You can still scroll horizontally by holding the other side button.
Overview
You can disable the horizontal scroll feature in Logitech Options+ under the Point & Scroll section.
Bluetooth mouse or keyboard not recognized after reboot on macOS (Intel-based Mac) – FileVault
If your Bluetooth mouse or keyboard does not reconnect after a reboot at the login screen and only reconnects after the login, this might be related to FileVault encryption.
When FileVault is enabled, Bluetooth mice and keyboards will only re-connect after login.
Potential solutions:
– If your Logitech device came with a USB receiver, using it will solve the issue.
– Use your MacBook keyboard and trackpad to login.
– Use a USB keyboard or mouse to login.

Backup device settings to the cloud in Logitech Options+
INTRODUCTION
This feature on Logi Options+ allows you to backup the customization of your Options+ supported device automatically to the cloud after creating an account. If you are planning to use your device on a new computer or wish to go back to your old settings on the same computer, log into your Options+ account on that computer and fetch the settings you want from a backup to set up your device and get going.
HOW IT WORKS
When you are logged into Logi Options+ with a verified account, your device settings are automatically backed up to the cloud by default. You can manage the settings and the backups from the Backups tab under More settings of your device (as shown):
Manage settings and backups by clicking on More > Backups:
– AUTOMATIC BACKUP OF SETTINGS — if the Automatically create backups of settings for all devices checkbox is enabled, any settings you have or modify for all of your devices on that computer are backed up to the cloud automatically. The checkbox is enabled by default. You can disable it if you don’t want the settings of your devices to be backed up automatically.
– CREATE A BACKUP NOW — this button allows you to backup your current device settings now, if you need to fetch them later.
– RESTORE SETTINGS FROM BACKUP — this button lets you view and restore all the available backups you have for that device that are compatible with that computer, as shown above.
The settings for a device are backed up for every computer that you have your device connected to and have Logi Options+ that you are logged into. Every time you make some modifications to your device settings, they get backed up with that computer name. The backups can be differentiated based on the following:
– Name of the computer. (Ex. John’s Work Laptop)
– Make and/or model of the computer. (Ex. Dell Inc., Macbook Pro (13-inch) and so on)
– The time when the backup was made
The desired settings can then be selected and restored accordingly.
WHAT SETTINGS GET BACKED UP
– Configuration of all the buttons of your mouse
– Configuration of all the keys of your keyboard
– Point & Scroll settings of your mouse
– Any application-specific settings of your device
WHAT SETTINGS ARE NOT BACKED UP
– Flow settings
– Options+ app settings

Flow network setup check for Mac
If you are having difficulty establishing a connection between two computers for Flow, follow these steps:
1. Check both systems are connected to the internet:
– On each computer, open a web browser and check the internet connection by navigating to a webpage.
2. Check that both computers are connected to the same network: Open the Terminal:
– For Mac, open your Applications folder, then open the Utilities folder. Open the Terminal application.
– In the Terminal, type: Ifconfig
– Check and note the IP address and Subnet mask. Make sure that both systems are in the same Subnet.
3. Ping the systems by IP address and make sure that ping works:Open the Terminal and type ping <IP address> [Where the <IP address is the IP address of the other computer noted in Step 2 above]
4. Check that the Firewall and Ports are correct:Ports used for Flow:
TCP 59866
UDP 59867,59868
1. Open the Terminal and type the following cmd to show the ports in use:
> sudo lsof +c15|grep IPv4
2. This is the expected result when Flow is using the default ports:
NOTE: Normally Flow uses the default ports but if those ports are already in use by another application Flow might use other ports.
3. Check that the Logitech Options Daemon is added automatically when Flow is enabled:
– Go to System Preferences > Security & Privacy
– In Security & Privacy go to the Firewall tab. Make sure the Firewall is on, then click on Firewall Options. (NOTE: You may have to click the lock in the bottom left corner to make changes which will prompt you to enter the account password.)
NOTE: On macOS, the firewall default settings automatically allow ports opened by signed apps through the firewall. As Logi Options is signed it should be added automatically without prompting the user.
4. This is the expected result: The two “Automatically allow” options are checked by default. The “Logitech Options Daemon” in the list box is added automatically when Flow is enabled.
5. If Logitech Options Daemon is not there, try the following:Uninstall Logitech Options
– Reboot your Mac
– Install Logitech Options again
– Disable Antivirus and reinstall:Try disabling your Antivirus program first, then reinstall Logitech Options.
– Once Flow is working, re-enable your Antivirus program.

Use Logitech Flow to copy an application on one device to the same application on another device
Logitech Flow lets you copy from an application on one device and paste into another device. You can copy and paste text, files, and images.
Logitech Flow does not modify the content copied, so the success of the copy and paste depends on the application. If the content that was copied from the application on the first computer is supported by the application on the second, then you should be able to copy the content from one device to another device when both have the same application (including application version).
Swap left and right buttons on Mac or Windows device using Logitech Options
