Here's how to forget a Wi-Fi network on your Mac

Besides clearing up a long list of Wi-Fi networks, removing networks from your Mac settings can improve your Mac performance. Everything your Mac stores that aren't needed can gradually make a Mac operate slower, reducing an otherwise good experience that most people have when using a Mac. 

So doing some tidying up, such as making a Mac forget a Wi-Fi network, is a small but useful contribution towards a Mac running smoother and faster again. Here are a couple of ways to quickly and easily forget a Wi-Fi network on a Mac. 

How to delete a Wi-Fi network on Mac? 

Firstly, you need to go to System Preferences. 

Either go through the Apple symbol in the top toolbar, or you can get to System Preferences through Spotlight Search, Siri, or using Finder. 

  1. Go to System Preferences
  2. Now click on Network > Advanced 
  3. This will show you a list of every Wi-Fi your Mac currently remembers
  4. For every Wi-Fi network you want to remove, use the “-” icon to forget and remove the settings (which means if you ever encounter that network again, you will need to enter the password to gain access)
  5. If you want to delete several at the same time, hold down the command key while clicking on the “-” icon.

Something else you can do while in the Network Settings is to adjust the settings for any given network. For example, you can set it so that you automatically join any of the networks on the list once in the connection range of that network. You can also tick a box - before going through to the Advanced Settings - to automatically ask your Mac to join new networks when it isn’t in range of any of the networks it remembers.

As you can see, forgetting a Wi-Fi network is pretty quick and easy. However, for those who want to do more to improve the performance of their Mac, there are apps that can help you with this and a whole lot more.
