How to Transfer Files from Mac to PC Wirelessly (5 Fast Methods Tested)

The friction between macOS and Windows is deliberate. Apple built AirDrop on proprietary Bonjour discovery and Apple Wireless Direct Link (AWDL), an ad-hoc Wi-Fi mesh layer that only operates between Apple Silicon and Intel Mac/iOS Wi-Fi chipsets. Microsoft built Nearby Sharing on Windows Wi-Fi Direct and Bluetooth BLE profiles incompatible with macOS.

When users turn to physical storage, they discover file system incompatibilities: Windows formats large external drives as NTFS (which macOS can read but cannot write to without kernel extensions), while macOS formats drives as APFS (which Windows cannot read at all).

This leaves wireless network transfer as the most practical everyday solution. However, relying on standard cloud lockers burns internet bandwidth and leaks confidential work to third-party databases. The ideal solution connects both machines directly over the local network via standard internet protocols.

We tested each wireless transfer method by moving a 10GB folder of mixed video, high-resolution RAW images, and code archives from an M3 MacBook Pro to a Windows 11 PC connected to a Wi-Fi 6 router:

Direct peer-to-peer browser transfer using ButterShare is the cleanest method for modern mixed-OS setups. You open ButterShare on both the Mac (Safari or Chrome) and the Windows PC (Chrome, Edge, or Firefox). When you enter the 6-character room code, the browsers establish a direct WebRTC data channel.

Files stream directly across your local Wi-Fi network without leaving your local environment. If both devices are on the same Wi-Fi router, data travels directly between the two network cards at speeds up to 80–120 MB/s without touching the outside internet.

If you regularly transfer files between the exact same two machines on a home or studio network, setting up native Server Message Block (SMB) sharing provides permanent shared folders without browser interaction.

On Windows: Right-click the folder you want to share > Properties > Sharing tab > Advanced Sharing > check 'Share this folder' > Permissions > grant Full Control to your Windows user account.

On Mac: Open Finder > press Cmd + K (Connect to Server) > enter 'smb://' followed by your PC's local IP address (e.g., smb://192.168.1.150) > click Connect > enter your Windows username and password. The shared PC drive mounts as a network volume in Finder.

Cloud storage remains popular because both macOS and Windows support native desktop sync clients. When you drop a file into your Google Drive or OneDrive folder on Mac, it syncs to the cloud and appears on your PC.

However, the performance penalty is severe for multi-gigabyte files. A 20GB video export requires 20GB of upload bandwidth from the Mac, followed by 20GB of download bandwidth on the PC. If your home internet connection has an asymmetric upload speed (such as cable internet with 20 Mbps upload), a 20GB transfer takes over 2.5 hours.

LocalSend is a widely praised open-source cross-platform file transfer client built with Flutter. Both the Mac and Windows PC install the native desktop binary, running a background daemon that announces the device via mDNS.

While LocalSend works well, it requires installing and granting local network firewall permissions to native software on both machines. For users on locked-down corporate laptops or guest computers where administrative install permissions are restricted, browser-based tools like ButterShare provide identical speed without software installation.

If you are traveling and do not have access to a local Wi-Fi router, you can create a direct ad-hoc connection between Mac and PC using a smartphone mobile hotspot or by enabling Windows Mobile Hotspot.

On Windows: Go to Settings > Network & Internet > Mobile hotspot > Turn On. Connect your MacBook to the Windows PC's Wi-Fi network. Once connected, open ButterShare on both devices. Because both machines now share a localized Wi-Fi subnet, files transfer device-to-device at high speed even without active cellular data.

If your transfer speeds between Mac and PC drop below 10 MB/s on a modern router, check these three common network bottlenecks:

1. Frequency Band Mismatch: Ensure both devices are connected to your router's 5GHz or 6GHz Wi-Fi band. If the Mac is on 5GHz and the PC falls back to the congested 2.4GHz band, maximum transfer throughput drops by up to 80%.

2. Windows Firewall Blocking: Windows Defender Firewall may classify your home Wi-Fi connection as 'Public' rather than 'Private', blocking local peer connections. Set your network profile to Private in Windows Network Settings.

3. AP Isolation on Router: Guest Wi-Fi networks and corporate routers frequently enable 'Access Point (AP) Isolation', preventing Wi-Fi devices from discovering one another. ButterShare handles this automatically via encrypted STUN/TURN fallback relays.
