While it can be great to have your device sign into a network automatically, it doesn’t take long for your computer to build up a long list of networks. If you haven’t removed old networks in a while, you could have passwords, IP addresses, and other network information saved on your Mac. Since hackers might be able to access that information, it’s a good idea to clean up your saved networks every once in a while.
