Captive Network Assistant

Contributor III

Has anyone here experienced this within their enterprise? We have a fairly large sized deployment and only began noticing CNA appear on 10.10 and 10.11.

These are all bound to AD as well, where as prior to 10.11 they were not.

Is this something we need to work with our Network engineers on? AD Team? or would something like Enterprise Connect solve this?

Thanks for any insight

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/ Active -boolean false

then restart it seems to disable it, just made this EA to report on each Macs status

#0 = false | 1 = true


if [ ! -f $file ]; then

echo "<result>no plist</result>"

exit 0


active=$( defaults read $file Active 2>&1 )

if [[ $active = *"does not exist"* ]]; then

echo "<result>no Active key</result>"


echo "<result>$active</result>"

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.
