How to forget a WiFi network on Mac

If you aren't sure, or have never done this before, then this article should be useful, about how to forget a network on a Mac. 

Besides clearing up a long list of WiFi networks, removing networks from your Mac settings can contribute towards improved performance. Everything your Mac stores that isn'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 WiFi network is a small but useful contribution towards a Mac running smoother and faster again. Here are a couple ways to quickly and easily delete a WiFi network on a Mac. 

How to delete a WiFi 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 WiFi your Mac currently remembers
  4. For every WiFi 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 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 WiFi 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.
