Creating a computer-to-computer Wi-Fi network in macOS

If you want to share the session without using an existing local area network, you can set up a temporary Wi-Fi connection between your Mac running Capture One Pro and an iOS device. This is sometimes referred to as an ad hoc connection. You can use this solution when you are on location and there is no network available, for example. The following description presumes that Wi-Fi is turned on already and the status icon is displayed in the menu bar.

1. Select the Wi-Fi options from the menu bar and click Create Network.

NOTE: if you have no “Create Network” option in macOS 11, open System Preferences and go to Network, select your Wi-Fi connection and click Advanced, enable the “Show legacy networks and options” preference.

2. It will ask you to name the network, the user name is by default:

NOTE: Channel has an impact on performance: creating a network on an already-congested channel will reduce the throughput, resulting in slow performance and possible loss of connection between Capture One and Capture Pilot.

3. It may ask if you wish to create an unsecure network, hit Create:

You will now see the network you created in the Wi-Fi menu bar:

4. You can now connect to this network using your iOS device.
NOTE: Switching networks can take some time. You will not be able to connect until the Wi-Fi symbol in the top left corner appears again. 

macOS has a built-in utility to help determine the optimal channel, Wireless Diagnostics. You can find it in Applications/Utilities or via Spotlight search.

On launching Wireless Diagnostics, you'll see this troubleshooting wizard dialog. You can ignore it. Instead, choose Window > Scan to bring up the Scan dialog:



This dialog presents a veritable boatload of information, but the key one here is the Best 2.4 GHz channel, highlighted above. When creating an ad-hoc network, it's best to use this channel as it has the least network traffic in the scannable environment.
