Recently we got some support request tickets regarding MAC clients which weren’t able to sign-in into Lync because they were missing the necessary root CA certificates.
Those root CA certificates are required in order to sign-in into Lync rather it’s on the internal or external network.
the following guide was written by a colleague of mine, Lior Gilboa and it explain how to install a root CA certificate on a MAC client:
Clearing Skype for Business Cache in macOS. Log out of and quit Skype for Business; Go to Finder; Press Command+Shift+G or click Go Go to Folder; Type /library and press Return; Delete the following bold files: Containers com.microsoft.SkypeForBusiness; Internet Plug-Ins MeetingJoinPlugin.plugin; Logs LwaTracing. Make sure that Skype for Business for Mac is latest updated version. See Follow the latest updates in Skype for Business You may try to check this issue via creating a new Mac user account and then performing a fresh install the latest Skype for Business on Mac from Office 365 portal to see whether the problem still occurs.

The following message will popup, change the Keychain to “System” and click ‘Add’. - You will be asked to put in your password to approve the Keychain modification,

That’s It.
