Hi,

When connecting MAC prompting for username and password . Once supplied it is asking "Do you trust the certificate ......."

The moment I click the trust certificate ,it just disappears and not connecting tto the wireless

its happening all mac laptop, but Iphones are connecting 

Thanks

What are you trying to connect to?
What WLC model?
What AP model?
What version of software?
If it's only affecting MAC it's more likely to be a MacOS bug - have you fully updated the MACs and contacted Apple support?
