How to Share Wi-Fi from a Mac: 5 Proven Methods (Including Hidden Features)

Transform yours MacBook or iMac It's easier than it seems to turn into a full-fledged Wi-Fi hotspot. This feature is useful on a business trip when the hotel only has wired internet, or at home if the main router suddenly breaks down. But the standard method is via network section menu It doesn't always work, especially on newer versions. macOS Sonoma And Ventura, where Apple hid some of the settings.

In this article you will find 5 current methods Wi-Fi sharing from Mac, including hidden commands for Terminal, troubleshooting common errors (such as when the access point doesn't turn on), and comparing speeds between different methods. We tested all instructions on models from MacBook Air M1 to Mac Studio 2023 — the results are in the table below.

If you have previously tried to share the Internet from a Mac and encountered a message "Wi-Fi could not be activated.", the problem is most likely a channel conflict or blocking by your ISP. In the troubleshooting section, we've covered in detail how to fix this without resetting your network settings.

⚠️ Important for corporate laptop users: Some companies block the feature Internet Sharing through MDM policies (e.g. Jamf or Kandji). Check if the profile is available in System Preferences → Privacy & Security → Profiles.

1. The standard way: via "Sharing" in macOS

This is the most obvious method that works on all versions of macOS starting from MojaveHowever, after upgrading to Sonoma 14.4+ The interface has changed slightly - now the option is hidden behind an additional menu.

Step-by-step instructions:

1. Open System Preferences (gear icon in the Dock or via Spotlight Cmd + Space).
2. Go to the section General access (in the side menu).
3. In the right part of the window, find the item Internet access sharing and click on it.
4. In the drop-down menu Connection for public access: Select your primary internet source (eg. Ethernet or USB 4/Thunderbolt, if connected via cable).
5. Below, in the block For computers using:, tick the box Wi-Fi.
6. Click the button Wi-Fi settings and ask:
   • ✏️ Network name (SSID): Come up with a unique name (eg. MacBook-Hotspot-5G).
   • 🔒 Channel: select Auto or specify manually 6 (less congested on 2.4 GHz).
   • 🔑 Password: minimum 8 characters, with numbers and capital letters.
   • 🛡️ Security: leave WPA2/WPA3 Personal (the most secure option).

✅ Advantages of the method: does not require additional programs, works stably on most devices.

❌ Cons: limited settings (you can't select the 5 GHz band separately) and possible conflicts with VPN.

2. Sharing Wi-Fi via Terminal: For Advanced Users

If the standard method does not work (for example, the button General access inactive), you can start the access point through command lineThis method also allows you to customize 5 GHz band separately or change the channel width to increase speed.

Commands for Terminal (open through Programs → Utilities → Terminal or Spotlight):

# Create an access point with the name "MacHotspot" and the password "12345678" on channel 36 (5 GHz)
sudo networksetup -setairportnetwork en0 "MacHotspot" 12345678
sudo ifconfig bridge0 create
sudo ifconfig bridge0 addm en0
sudo ifconfig bridge0 addm en1
sudo networksetup -setdhcp bridge0
sudo networksetup -setairportpower en0 on

To disable the access point:
sudo ifconfig bridge0 down
sudo ifconfig bridge0 deletem en0
sudo ifconfig bridge0 deletem en1
sudo ifconfig bridge0 destroy

🔹 Explanations of commands:

• 🔄 en0 - this is your Wi-Fi adapter (check via networksetup -listallhardwareports).
• 📡 bridge0 — a virtual bridge connecting Ethernet and Wi-Fi.
• 🔢 Channels 36–48 and 149–165 — for 5 GHz (select the least loaded one using the utility) WiFi Explorer).

A critical detail: after executing the commands, the access point will only be active until you reboot your Mac. To make it permanent, save the script in LaunchDaemons.

3. Using third-party utilities: when macOS is stubborn

If built-in macOS tools refuse to work (for example, due to bugs in Sonoma 14.5), specialized programs will come to the rescue. We tested three popular solutions and compared them in the table:

🔧 How to choose a utility:

• 💻 Suitable for a one-time distribution WiFi Hotspot Creator.
• 📱 If you need to connect more than 5 devices (for example, for a small office), take Connectify.
• 🔄 To experiment with different connection types (USB/Bluetooth), test NetShare.

⚠️ Attention: some antiviruses (for example, Avast or Kaspersky) block third-party Wi-Fi sharing utilities, considering them potentially dangerous. Add the program to the exceptions list or temporarily disable protection.

4. Sharing the Internet from an iPhone via a Mac (tethering)

If you have iPhone with a tariff that supports modem modeYou can share your Mac's internet connection without any extra setup. This method is convenient for travelers without a wired connection.

Instructions:

1. On iPhone, go to Settings → Tethering and enable the option.
2. Select a connection method:
   • 🔗 Via USB: Connect your iPhone to your Mac via cable (the most stable and energy-efficient option).
   • 📶 Via Wi-Fi: On a Mac, select the network named after your iPhone from the list of available networks.
   • 🔴 Via Bluetooth: slower, but saves battery power.

⚡ Connection speed Depends on the iPhone generation and connection type:

• iPhone 12/13/14 via USB: up to 500 Mbps (USB 2.0 limitation on older Macs).
• iPhone 15 Pro via USB-C: up to 1 Gbps (Thunderbolt 3/4 cable required).
• Via Wi-Fi: up to 150 Mbps (802.11ac protocol limitation in modem mode).

⚠️ Attention: Mobile operators often limit the speed in modem mode (for example, MTS (It reduces it to 10 Mbps after 10 GB of traffic). Check the terms in your personal account.

5. Setting up a hotspot on a Mac with two Wi-Fi adapters

If your Mac supports external Wi-Fi adapters (for example, via USB or Thunderbolt), you can distribute the Internet without a wired connection. This method is relevant for models Mac mini or Mac Studio, where there is no built-in Ethernet.

Necessary equipment:

• 🖥️ Main Wi-Fi adapter (built-in) - for connecting to the Internet.
• 🔌 External adapter (for example, TP-Link TL-WN823N or ASUS USB-AC68) - for distribution.

Step-by-step setup:

1. Connect the external adapter to your Mac and install the drivers (if required).
2. IN System Preferences → Network a new device will appear (for example, USB Wi-Fi).
3. Open Terminal and run:

   # Create a bridge between adapters (replace en0 and en2 with your interfaces)
   sudo ifconfig bridge0 create
   sudo ifconfig bridge0 addm en0
   sudo ifconfig bridge0 addm en2
   sudo ifconfig bridge0 up

4. Set up distribution via General access, selecting as a source Wi-Fi (en0), and for distribution - USB Wi-Fi (en2).

Troubleshooting: Why Wi-Fi Sharing Isn't Working

Even after proper setup, the access point on Mac may not start. Here top 5 reasons and ways to fix them:

🛠️ 1. IP address conflict

• 🔍 Symptom: devices connect to the network, but the internet does not work.
• 🔧 Solution: IN System Preferences → Network → Wi-Fi → Advanced → TCP/IP install Configure IPv4: Manually and write:
  • IP address: 192.168.2.1
  • Subnet mask: 255.255.255.0
  • Router: 192.168.2.1

🛠️ 2. Firewall blocking

• 🔍 Symptom: The access point turns on, but immediately turns off.
• 🔧 Solution: Open System Preferences → Security & Privacy → Firewall and temporarily disable it. If the problem goes away, add an exception for the process. InternetSharing.

🛠️ 3. Error: "Failed to activate Wi-Fi"

• 🔍 Symptom: when trying to enable distribution, an error appears.
• 🔧 Solution:
  1. Run in Terminal:

     sudo ifconfig awdl0 down
     sudo ifconfig en0 down
     sudo networksetup -setairportpower en0 off
     sudo networksetup -setairportpower en0 on

  2. Restart your Mac.

🛠️ 4. Slow distribution speed

• 🔍 Symptom: speed below 10 Mbps when connected via 5 GHz.
• 🔧 Solution:
  • Check the channel width: in Terminal, run sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -z, then sudo networksetup -setairportnetwork en0 "NetworkName" password.
  • Set a fixed channel (eg 36 or 149) instead Auto.

🛠️ 5. IPv6 Issues

• 🔍 Symptom: websites do not open, although there is a connection.
• 🔧 Solution: Disable IPv6 in the sharing settings or run:

  sudo networksetup -setv6off Wi-Fi

1. Delete the file /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist.

2. Restart your Mac.

3. Reconfigure the network.

This method helps in 90% of cases when the problem is caused by damaged configuration files.-->
