Sometimes when I switch Wi-Fi network or connect to a VPN via Global Protect the memory usage of /System/Library/CoreServices/WiFiAgent.app shoots up and my fans go mental. Why?

enter image description here

This screenshot is one of the worst times it has happened, the usage is not alway consistent sometimes its 2GB, sometimes 6GB etc etc

  • Hi Will, I've identified the Wi-Fi application on my computer and it's not using a large amount of memory. I presume you're using the latest version of Mojave? – Ezekiel Elin Feb 26 '19 at 15:28
  • @EzekielElin I believe that I am, if not I shouldn't be too far out of date. For the most part the application works fine like yours is but sometimes it spikes and it spikes high! – Will Poole Feb 26 '19 at 15:46
  • Thanks, there was enough information to identify the application involved (which is part of macOS actually). No clue what's going on though. – nohillside Feb 26 '19 at 18:20
  • Taken from @chrisdahfuh's answer: "Also, are you streaming/uploading/downloading anything? I see Google Chrome is using 1GB? Does it only happen when Google Chrome is open?" – nohillside Feb 26 '19 at 18:21

This link provides instructions on how to reset your wifi configuration and removing/resetting specific plist files on your system under "Make a New Wi-Fi Configuration in MacOS Mojave" (with other useful Wifi tips), it could possibly help:



This is expected if you have a lot of networking. I'll close this as a duplicate of a couple questions covering this, but if you @ me in comments if you edit this to cover new ground we can revisit the hold / close.
