Captive Portal not working with Apple devices

[spatiald]

Background

NOT WORKING - OSX 10.11.6
WORKING - Windows 10
NOT TESTED - Debian

Problem

On OSX, logging onto the RACHEL AP doesn't spawn a working captive portal page nor does it redirect when you try to surf to site (the latter usually happens if no traffic triggered the original popup).

Logs

OSX connnection

It spawns this captive portal box:

Windows 10 connnection

It works (redirects to captive portal page) but drops one error.

Just fixed the Win 10 error -- will look into the mac problem

[needlestack]

So it looks like this is working in the latest Mac OS (Sierra). I don't have a device with an older version to test with. Can you replicate it? I have some things you could try...

Not Working on OSX 10.11.6 (El Capitan) - let's put a hold on this issue while I test some more stuff on my own system. Maybe a laptop issue.
