Open the Network section in your Mac’s System Preferences window. Select “Wi-Fi” and click the “Advanced” button; you will then be able to drag networks in the Preferred Networks list to re-order them. This option is no longer available in macOS 13.0 Ventura, but it still works on older versions of macOS.
By default, your Mac automatically connects to the most-recently-used Wi-Fi network. But if your home has multiple networks, you might want to prioritize one in particular on your Mac. Here’s how to change your default wireless network on Mac.
Unfortunately, this is no longer possible as of macOS 13.0 Ventura, which was released on October 14, 2022. It’s still possible if your Mac is running an older version of macOS or Mac OS X.
You can reorder the Wi-Fi network priority list from the Network section in System Preferences.
The easiest way to get to the Network Preferences is from the Wi-Fi section in the menu bar. Click on the Wi-Fi icon from the menu bar and then select the “Network Preferences” option.
This opens the Network section from within the System Preferences.
Here, from the sidebar, make sure that the “Wi-Fi” option is selected and then click on the “Advanced” button.
You’ll see a “Preferred Networks” section in the “Wi-Fi” tab that contains a list of all the networks to which you’ve previously connected. Everything is sorted by preference, meaning that the network on the top of the list gets the first preference.
From this list, find the network that you want to be your preferred network (such as your hotspot). Click on the network to select it.
From there, drag the network name to the top of the list and then release it.
Once you see the network at the top of the list, it means that it has priority. You can now reorder the rest of the Wi-Fi networks for the second or third priority.
If you’ve previously connected to an open Wi-Fi network and don’t want your Mac to connect to it, even when no other priority network is available, remove the Wi-Fi network from the list. Select the Wi-Fi network and then click on the Minus button.
Once you’ve prioritized the list of networks, click on the “OK” button from the bottom-right corner.
Then, from the Network screen, click on the “Apply” button to update the priority list.
If you don’t want to remove a network from the list, you can also stop your Mac from automatically connecting to a specific Wi-Fi network.
