Hi @wait
Did you make any progress on this ?
I'm just testing the upgrade to 10.11 and noticed that the Captive Network Assistant pops up, i'm assuming it's because the Mac hasn't authenticated to our proxy and can't reach here,
this article explains has some detail
if i run
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.captive.control Active -boolean false
then restart it seems to disable it, just made this EA to report on each Macs status
#!/bin/sh
#0 = false | 1 = true
file=/Library/Preferences/SystemConfiguration/com.apple.captive.control.plist
if [ ! -f $file ]; then
echo "<result>no plist</result>"
exit 0
fi
active=$( defaults read $file Active 2>&1 )
if [[ $active = *"does not exist"* ]]; then
echo "<result>no Active key</result>"
else
echo "<result>$active</result>"
fi
No progress yet, we're still without Casper in our environment. And its gotta be related to Proxy somehow, our network is very expansive and somewhat convoluted as well.
