What is the application Wi-Fi, and why is it gobbling 2GB of memory? Running latest version of macOS Mojave 10.14.1 on a 2018 MacBook 15" with 16GB of memory total.

  • I have the same issue on 10.14.4. Using Activity Monitor to quit seems to reset the memory usage back down to <5 mb with no ill effects that I've noted so far. I don't see anything interesting in the "open files and ports" tab or in "sample process." – n8henrie Mar 29 at 14:25
