Devices no longer displayed after macOS Catalina update
5 posts · Closed
After the most recent macOS Catalina update, WiFi Guard on my iMac no longer displays some of my devices that it used to detect before. I also have WiFi Guard installed on a Windows PC, and it still discovers and displays all my devices with no problems at all.
Is this issue related to something Apple broke/changed in the latest update? Or am I overlooking some important setting in macOS WiFi Guard?
This missing device issue is indeed caused by the latest macOC Catalina update. Apple decided to make some changes in ARP format, which caused certain network functions to break.
We received messages from other users describing identical problems over the past few days, and currently working on finding a solution. We will post an update here once a fix is available.
Solution: please download the new build of WiFi Guard and replace your already installed copy. After that, everything should again work properly and all devices should be discovered.
Thank you for the prompt response!
It has fixed the problem. Now iMac WiFi Guard detects all my devices, exactly like the PC. Everything works great (tu)
Perfect, SoftPerfect! :-) All excellent now. Thank you for fixing this so quickly.
I only wish Apple would stop wrecking things in every update...
