wifi not working - captive portal login screen does not appear

I can reach hotspot login page using Safari trying to access a HTTP address when I login with a non-admin user. If user is admin, Safari can't reach the hotspot login page. If the URL is HTTPS, Safari can't help as well.

The only thing that really fixed it for me was to remove all .plist files from /Library/LaunchAgents and /Library/LaunchDaemons directories.

Of course it caused me some trouble and I needed to reinstall some softwares after that, but it really got the issue fixed :/

type in the url for login into a browser. It will say "no internet". Now, log out of the system. Tick the box which says reopen windows when logging back in. Log back in, now the browser url should load. Sometimes, i have to log in and out 2 times in a row to get it to work. I know that this is not a good solution, but i thought i might as well take some time out of my day to write this since i've read some of the users rebooting to fix this issue( consumes more time than log out/in).

I got it to work! Instead of deleting EVERYTHING in the launchdaemons/launch agents folders, i looked through the files and saw two files related to two old VPN services I have since uninstalled and no longer use. Tunnelblick and PIA VPN. I deleted just those two files, rebooted my mac, and boom everything is working now.

This guy nailed a good solution.

I didn't bother with creating my own launch daemon, but instead just created a shortcut to the Captive Network Agent app on my desktop. It appears it'll work until Apple can fix this sloppiness.

The fix for me was just manually opening the captive log in prompt.

Open terminal

Type

open /System/Library/CoreServices/Captive

Then press tab a couple times and it should auto complete the rest for the captive application then press enter and it opened right up and was on the correct captive login page

This is the best and most straight forward solution! Though I have no idea if by deleting the files will affect my other program but since it’s a launch agent and daemon, I suppose they will reload when the particular program needs it.

Had the same issue since Catalina update and have tried all the suggested fixes on here with varying degrees of partial success(es) - the deletion of the /Library/LaunchDaemons and LaunchAgents worked briefly and also prompted me to delete a number of unused Apps but then reverted to the same problem after a few connections to various guest wifi networks.

However today after the OS 10.15.2 update it has completely fixed the problem, so it would appear t be an OS issue all along.

Try booting into safe mode. It should let you log in normally. Then reboot to normal mode.

It works after I remove everything under /Library/LaunchDaemons and /Library/LaunchAgents then restart.

Type a url into the nav bar of the browser and try to navigate to that site. This may force the sign in/acceptance screen to open.

I have exactly the same problem. Been trying to log-in at a hotel and not at an airline lounge. The Phone/iPad all working fine. MacOS will not bring up the login page.

I have the same exact problem. The only workaround is to use my iPhone as a wifi hotspot, but this is driving me crazy.

Same problem... huge issue for me as I work remotely in areas that have unsecured public WiFi as the only method to connect. My phone signal is top weakness to use the hotspot. Need HELP !!!
