How to Create a Wi-Fi Hotspot on a MacBook: 3 Working Methods + Security Tips

In the section For computers using (To computers using) tick the box Wi-Fi.

Click Wi-Fi settings (Wi-Fi Options) and ask:

• 📛 Network name (SSID) - in Latin, without spaces;
• 🔒 Channel — choose Auto or specify manually 6 (less busy);
• 🔐 Password — minimum 8 characters, with numbers and letters.

• Go back to the main window and check the box to the left of Public InternetConfirm launch in the window that appears.

Done! Other devices can now connect to your network. If the hotspot doesn't appear, check that System Preferences → Wi-Fi mode is on Turn on Wi-Fi (even if you distribute the Internet via cable).

Make sure your MacBook is connected to the internet|Disable VPN (if used)|Select a free Wi-Fi channel (6, 11, or 40)|Set a strong password (at least 8 characters)|Enable Internet Sharing in Settings-->

3. Method 2: Distribution via Terminal (for experienced users)

If the macOS menu does not allow you to create an access point (for example, due to bugs in Sequoia), can be used command lineThis method is also useful for customization hidden network (hidden SSID) or changes in the Wi-Fi standard (for example, to 802.11n for compatibility with older devices).

Open Terminal (Programs → Utilities → Terminal) and execute the commands in order:

# Create a hotspot with the name "MyMacHotspot" and password "12345678"
sudo networksetup -setairportnetwork en0 "MyMacHotspot" 12345678

Enable Internet sharing (replace "Ethernet" with your source)
sudo sysctl -w net.inet.ip.forwarding=1
sudo natd -interface en0
sudo ipfw add divert natd ip from any to any via en0
sudo ipfw add pass all from any to any

To disable distribution, run:

sudo networksetup -setairportpower en0 off
sudo sysctl -w net.inet.ip.forwarding=0

⚠️ Attention: When using the Terminal don't close the window until the sharing session ends. This may result in network settings being disrupted. If Wi-Fi stops working after disconnecting, reboot MacBook or reset network settings via System Preferences → Network → Advanced → TCP/IP → Renew DHCP.

How to check which interface to use instead of en0?

In Terminal, run the command networksetup -listallhardwareports. Find the section Wi-Fi and copy the value Device (For example, en0, en1).

4. Method 3: Third-party programs for distributing Wi-Fi

If the built-in macOS tools don't work (for example, on MacBook Pro 2017–2019 with bugs in Sonoma), you can use third-party utilities. They offer additional features: traffic limiting, device blacklisting, and automatic shutdown by timer.

Program	Pros	Cons	Price
WiFi Explorer	Channel analysis, 5 GHz support, manual MTU configuration	Paid (free 7-day trial)	~$20
NetSpot	Network coverage visualization, compatibility with M1/M2	The free version is limited to 3 connected devices.	Free / $49
Create Hotspot	Simple interface, WPA3 support, no root required	Advertising in the free version	For free

To install, download the program from the official website (for example, NetSpot With netspotapp.com) and follow the setup wizard's instructions. Usually, this is enough:

1. Select the Internet source (Ethernet/USB).
2. Set the network name and password.
3. Specify a range of IP addresses (default 192.168.2.1–192.168.2.100).
4. Click Start Hotspot.

5. Typical problems and their solutions

Even with the correct settings, Wi-Fi distribution on MacBook may malfunction. Let's look at the most common errors and how to fix them.

🔴 Problem: Access point is not visible on other devices

• 📡 Check your Wi-Fi channel. If selected Auto, try specifying it manually 6 or 11 (less busy).
• 🔄 Restart the Wi-Fi module: sudo ifconfig en0 down && sudo ifconfig en0 up.
• 🛡️ Disable your firewall: System Preferences → Security & Privacy → Firewall → Off.

🔴 Problem: I'm connected, but the internet isn't working.

• 🔌 Check your internet sourceIf you are using Wi-Fi as a source, make sure that MacBook connected to a network with internet access (not to another access point).
• 🔧 Flush your DNS: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.
• 📶 Change the Wi-Fi standard. IN Wi-Fi parameters select 802.11n instead of 802.11ac (if you are connecting an old device).

🔴 Problem: macOS automatically disables sharing

This is a typical mistake on MacBook With M1/M2 due to energy saving. Solution:

1. Open System Preferences → Battery.
2. In the section Energy saving uncheck Dim the display slightly when running on battery power.
3. Check the box Prevent the computer from automatically going to sleep when the display is turned off.

6. Security: How to protect your access point

Wi-Fi distribution with MacBook — convenient, but unsafe. If you don't set up security, outsiders can connect to your network, which can lead to:

• 🕵️‍♂️ Traffic theft (slow internet);
• 💻 Data interception (passwords, cookies);
• 📡 DDoS attacks (if your IP will be used for attacks).

Minimum safety measures:

1. Use WPA3. IN Wi-Fi parameters select Security: WPA3 Personal (if supported by devices).
2. Complex password. Example: k7#pL9!mQ2$vR5 (12+ characters, case-sensitive and special characters included).
3. Limit the number of devicesManually add MAC addresses of allowed gadgets (in NetSpot or via Terminal).
4. Turn off distributionwhen it's not needed. Leaving the access point running for long periods of time increases the risk of hacking.

For advanced protection, install Little Snitch (monitoring network connections) or Lulu (blocker of unauthorized outgoing connections). These programs will help you detect if an unauthorized device connects to your network.

7. Alternative ways to share the Internet from a MacBook

If Wi-Fi isn't working for some reason, you can share the Internet in other ways:

• 🔗 USB tethering. Connect iPhone or Android- smartphone via USB and enable modem mode in the phone settings. MacBook will automatically get access to the mobile Internet.
• 🔌 Ethernet bridgeIf you have MacBook Pro with an Ethernet port (or adapter), connect the cable to the router and use Internet Sharing for distribution via Wi-Fi.
• 📶 Bluetooth tetheringSlower than Wi-Fi (up to 3 Mbps), but uses less battery. Turns on in System Preferences → Bluetooth → Advanced.

For USB tethering with iPhone:

1. Connect your phone to MacBook via Lightning/USB-C.
2. On iPhone open Settings → Tethering and turn it on Allow others.
3. On MacBook V System Preferences → Network a new connection will appear iPhone USB.

8. Frequently Asked Questions

❓ Is it possible to share Wi-Fi from a MacBook without a password?

Technically yes, but it's extremely insecure. To create an open network, Wi-Fi parameters select Security: NoHowever, in this case:

• Anyone can connect to your network;
• Traffic will be transmitted without encryption;
• Some devices (eg iPhone) may block connections to open networks.

We recommend using at least WPA2 Personal with a simple password (for example, 12345678).

❓ Why is my internet speed lower when sharing from my MacBook than on my main connection?
This is normal: when distributing Wi-Fi MacBook acts as a router, and some of the speed is lost on:
• Packet processing (CPU load);
• Retransmission of data (retransmission);
• Wi-Fi module limitations (for example, 802.11ac on MacBook Air M1 supports maximum 867 Mbps).
To reduce losses:
• Use the channel 5 GHz (if devices support it);
• Disable background applications (Torrent, cloud synchronization);
• Connect MacBook to the Internet via cable (Ethernet), not via Wi-Fi.
How do I share Wi-Fi from a MacBook to a Windows PC?
The connection algorithm is no different from other devices:
1. On MacBook turn on distribution (see Method 1).
2. On Windows-open on your computer Settings → Network and Internet → Wi-Fi.
3. Select the network with the name of your access point and enter the password.
If Windows does not connect:
• Check that on MacBook V Wi-Fi parameters mode selected 802.11n (and not 802.11ac);
• Update the Wi-Fi adapter driver on your PC;
• Turn it off Windows option Random hardware addresses (random hardware addresses) in Wi-Fi settings.
❓ How many devices can I connect to a MacBook hotspot?
The theoretical limit is up to 10 devices, but in practice, stable operation is possible with 3-5 gadgets. With more:
• The load on the CPU increases (especially on MacBook Air);
• Speed ​​drops due to channel splitting;
• Connection interruptions may occur.
To connect >5 devices we recommend:
• Use an external Wi-Fi adapter (for example, TP-Link TL-WN823N);
• Limit traffic for each device via NetSpot;
• Switch to Ethernet distribution (if the source allows it).
❓ Does Wi-Fi sharing work on a MacBook running macOS Sequoia (2026)?
Yes, but with some reservations:
• On MacBook with chips M3 distribution through Internet Sharing may require confirmation via Touch ID;
• IN Sequoia option added Low Power Mode for Wi-Fi, which can turn off the access point when the battery is low;
• Some older utilities (eg. Create Hotspot) may not support Sequoia without update.
If the distribution does not work:
1. Update macOS to the latest version;
2. Reset network settings (System Preferences → Network → Advanced → Reset);
3. Try alternative methods (USB tethering, Bluetooth).
