How To Disable Wi-Fi Auto-Join in macOS

By default, your Mac will automatically join known Wi-Fi networks whenever they are available. Your Mac will try to auto-join the Wi-Fi network you have most recently connected to. However this feature may become very annoying for you, especially if your Mac is trying to connect public Wi-Fis or hotspots etc. (instant hotspots not working?)

You may not want to auto-join Wi-Fi networks with poor connectivity like the ones in coffee shops, Internet cafes, hotels, shopping centers, libraries, bus terminals, airports etc. For instance, you go to your local Starbucks or library, you open your Mac and you keep getting hotspot notification pop ups that you do not want to connect to. You close it and a few minutes later it pops up again.

As stated above, auto-join is enabled by default. Furthermore, once you disable auto-join for a network, your change will sync over iCloud, assuming your iOS and macOS devices are logged into the same iCloud account.
