Public wifi login page isn't triggered

Hello and welcome to Apple Support Communities, Mike!

I understand you're not able to sign onto public Wi-Fi due to the login portal never appearing. I'd be happy to provide information to help you address this.

Try connecting to that Wi-Fi network while in safe mode: Use safe mode to isolate issues with your Mac

Let us know the results.

Have a great day!

I have this problem to.

There's a small "helper" called "Captive Network Assistant" that's supposed to check if you're on a network that wants to redirect you to a login page, and then launch that page in a login window.

Apparently there's a bug in MacOS that prevents that app from starting and running as it should, but thankfully it can be launched manually:

1. Go to [Your startup disk name]/System/Library/CoreServices
2. Dubble click "Captive Network Assistant.app" - The login prompt should appear now
3. Optional: Make an alias of it and place on your desktop for easy access every time you're on a public wifi.

Same issue -- have had 3 support calls with Apple since I upgraded and still no answer other than boot in safe mode -- I've had to boot in safe mode easily 100 times the past month because I work on the road so much -- Starbucks, McDonald's, Airports, Hotels......major issue. Still no help from Apple

THANK YOU!!!!!! That did the trick so far -- saw your message and drove right to a McDonald's to try it -- worked perfectly. Please share your answer with Apple since they wasted hours and hours of my time by not suggesting this. Seriously think it's because they don't like to admit they have bugs so they ignore them or try to cover them up until they can be "magically" fixed. My 3 supports calls were all Apple telling me I had something wrong with MY software or something that I installed on my computer was breaking it and their security change was for my own good. Thanks much.

You're welcome! 😊
