📂 High-Speed File Tunnel

This solution adopts a "Dual-track" strategy:

1. SMB Protocol: Mounts the Mac hard drive as a Windows network drive, suitable for large file reading/writing and code editing.
2. LocalSend: Suitable for ad-hoc transfer of images and text across devices, similar to AirDrop.

Method 1: System-level Mounting (SMB) - Recommended

Configure this once and benefit forever. Once configured, Mac folders will appear in Windows "This PC" just like a USB drive.

Step 1: Enable Sharing on Mac (Server)

1. Open Settings:
   • Click the Apple icon  in the top left -> System Settings.
2. Find Sharing:
   • Click General -> Sharing.
3. Enable File Sharing:
   • Find File Sharing and toggle the switch on the right.
   • Click the "i" icon on the right (Details/Settings).
4. Add Shared Folders:
   • Under the "Shared Folders" section, click the "+" button.
   • Select the folder you want Windows to access (adding "Downloads" or "Desktop" is recommended; Administrator accounts have access to all paths by default).
5. ⚠️ Critical Step (Most Important!):
   • Click the "Options..." button in the same window.
   • Ensure "Share files and folders using SMB" is checked.
   • Crucial Step: In the "Windows File Sharing" list below, you must check your account name.
   • The system will prompt for a password; enter your Mac login password to confirm.
   • Click "Done".
6. Note the Address:
   • With "File Sharing" enabled, you will see a line of small text: "Users on your network can access your computer at smb://192.168.x.x".
   • Write down this IP address (e.g., 192.168.1.5).

Step 2: Connect from Windows (Client)

1. Open Run Window:
   • Press Win + R on the Windows keyboard.
2. Enter Address:
   • Enter the Mac's IP address.
   • Note: Windows must use backslashes \, not smb://.
   • Format: \\192.168.x.x
   • (e.g., If Mac says 192.168.1.5, you enter \\192.168.1.5)
   • Click OK.
3. Enter Authentication:
   • Windows will pop up a login box.
   • Username: Enter your Mac username.

     💡 Tip: If you are unsure what the username is, open Mac Terminal and type whoami; the name displayed is the correct system username.

   • Password: Enter your Mac login password.
4. Connection Successful:
   • If validation passes, the Mac's shared folder will appear in the Windows File Explorer.

Pro Tip: Map Network Drive In the opened shared folder window, right-click the folder -> Select "Map network drive" -> Assign a drive letter (e.g., Z:) -> Check "Reconnect at sign-in". This way, the Z: drive remains available after restarting the computer, without re-entering the IP.

Method 2: LocalSend (Ad-hoc Transfer)

If you don't want to configure complex network sharing and just want to send a picture to the computer next to you, LocalSend is the best choice. It is an open-source, free AirDrop alternative.

1. Download & Install:
   • Download and install LocalSend on both Mac and Windows.
2. How to Use:
   • Ensure both devices are connected to the same WiFi.
   • Open the app; they will automatically discover each other.
   • Select File -> Click the other person's avatar -> Send.
3. Settings Suggestion:
   • Enable "Quick Save" in settings so you don't have to manually click "Accept" when receiving files, making the experience smoother.
