Problem

You work across Windows and macOS and want the MX Master 3S to feel consistent on both. You need clear guidance on pairing methods, modifier differences such as Ctrl and Command, scroll direction, per app profiles, and common issues like permissions on macOS or power management on Windows.

Solution

Pair the MX Master 3S to both systems on separate Easy Switch channels, install Logi Options+ on each, and sign in with the same Logitech account to sync settings. Standardize key behaviors such as scroll direction and button mappings across platforms, and enable Logitech Flow for seamless cursor movement. Grant Accessibility and Input Monitoring permissions on macOS and review Bluetooth and power settings on Windows for reliable reconnection.

Step-by-step instructions

1) Pair to both systems and label channels

1. On the mouse, pick Channel 1 for Windows and Channel 2 for macOS.
2. Put the mouse in pairing mode and connect to Windows via Bluetooth or Logi Bolt.
3. Repeat for macOS on its own channel.
4. In Logi Options+, rename channels for clarity such as Windows on 1 and Mac on 2.

2) Install Logi Options+ and sign in on both

1. Install Logi Options+ on Windows and macOS.
2. Sign in with the same Logitech account so profiles and settings can sync where supported.
3. Let Options+ run at startup on both systems.

3) Align core behaviors for muscle memory

1. In Point and Scroll, set the same DPI and Cursor speed on both machines.
2. Choose the same scroll direction on both so vertical scrolling feels identical.
3. Map the same Global button actions on both. For example, back and forward, middle click, and gesture directions.

4) Handle modifier differences

1. When assigning Keystroke actions, mirror platform shortcuts.
   • On Windows use Ctrl combinations.
   • On macOS use Command equivalents.
2. For cross platform consistency, create App specific profiles that map to each app’s native shortcuts so your buttons do the same thing even if the keys differ.

5) Enable Logitech Flow for cross computer control

1. In Options+ > Flow, sign in on both computers and ensure they are on the same network.
2. Arrange monitors in Flow and test cursor movement across the edge.
3. Turn on Clipboard and File sharing if you want to copy content between systems.

6) Grant permissions on macOS

1. Open System Settings > Privacy & Security.
2. Under Accessibility and Input Monitoring, enable permissions for Logi Options+ and the Logi Options+ Daemon.
3. Restart Options+ if prompted so button mappings and gestures work consistently.

7) Improve reconnection reliability

1. On Windows laptops, disable aggressive USB power saving for the receiver in Device Manager if you use Logi Bolt.
2. Place the receiver on a short USB extension near the mouse to reduce interference.
3. Keep firmware and Options+ updated on both systems.

8) Create per app profiles on each platform

1. Add profiles for browsers, Office apps, editors, and creative tools on both Windows and macOS.
2. Assign the same functional actions even if the keystrokes differ.
3. Test and refine so the same buttons perform the same jobs across platforms.

Optional methods or tools

• Logi Bolt on Windows and Bluetooth on macOS to diversify radios if you see interference.
• PowerToys on Windows and BetterTouchTool on macOS for additional window management that you can trigger from mouse buttons.
• Cloud sync in Options+ so layouts follow you after reinstalls or hardware swaps.

Best practices or tips

• Keep DPI, cursor speed, and scroll direction identical across both systems.
• Use the gesture button for universal actions that exist on both platforms such as new tab, mute, or screenshot.
• If mappings stop working on macOS, recheck Accessibility and Input Monitoring permissions after OS updates.
• If Windows resumes from sleep and the mouse hesitates, wake it by clicking once and ensure the receiver is not behind a metal case.
• Revisit your layouts after a week and promote the most used actions to the easiest buttons for both platforms.

Using the MX Master 3S across Windows and macOS is smooth when you standardize the fundamentals. Matching DPI, scroll direction, and core button functions gives you consistent muscle memory, and Logitech Flow ties the experience together by letting the cursor and clipboard move where you work. App specific profiles ensure your buttons trigger the right shortcuts regardless of whether the keys are Ctrl based or Command based.

If you hit snags, focus on permissions and radios. macOS needs Accessibility and Input Monitoring enabled for Options+, while Windows benefits from receiver placement and sensible power settings. With firmware current and Options+ signed in on both sides, the MX Master 3S becomes a dependable cross platform tool that adapts to each app without making you relearn your workflow.
