How to create a password protected ad-hoc network on Yosemite

I just tried to create an ad-hoc network on OS X Yosemite and noticed there are no password options. Are they hidden? If so, is there any way to enable them? Is Terminal an option?

Is it possible to create a password protected ad-hoc network on yosemite? If so, how?


You can create a password-protected ad-hoc network by sharing your internet connection. To do so:

  1. Go to Apple Menu -> System Preferences
  2. Go to Sharing preference pane
  3. Select "Internet Sharing"
  4. Choose the source port
  5. Set your connection to be broadcast over WiFi
  6. Click on WiFi options and set a network name and security

While this is a little more involved than just creating the ad-hoc, it will serve the same purpose as well as having the benefit of sharing your connection. At this time, there is no way to add security to an ad-hoc only network on Yosemite.

As a newer answer for making an ad hoc network that works in Mojave without a internet connection, while searching online, I finally found an answer!

Smoooosher's answer only works with an active connection to share.

To create your own "active" network, in terminal run the 2 following commands.

sudo networksetup -createnetworkservice Loopback lo0
sudo networksetup -setmanual Loopback 172.20.42.42 255.255.255.255

This creates a new network conection that although it looks inactive, it can be shared from the internet sharing preference pane to wifi.
