The silent presenter in a join.me meeting.

I am doing a test run with a presenter for a PD day and we are using join.me meeting web browser interface for it.  She can hear me but I can not hear her, be it on our: Macbook or Windows 10 laptop (hardwired or connected via Apple TV).  When I run a test for an audio signal using the join.me interface I do hear the "air raid horn" sound effect on all devices but I still can not hear the presenter.  I can hear the presenter on the MacBook alone but when connected to the TV or Apple TV I lose her audio. Then it hits me, maybe it is the browser??  I was using Google Chrome, so I decide to try IE  and in the process it advises me to install the join.me client.  I enter the meeting code et voila, I can hear her.  Who knew?!?  It is the simple things in life that make me happy.

What happens when your Macbook says it can not connect to your Apple TV.

You have the best plans for this next class, you are going to have them use Kahoot to go over the latest English terms...uno problemo...your MacBook keeps telling you that it can not connect to your Apple TV.  You have checked your connections, you are on the same network and all that fun stuff still nothing.  You call IT.  They can connect with their iPhone and your iPad, so what gives???  It seems as though your Apple TV has updated itself to its latest software rendering unrecognizable by the MacBook because it is running an older iOS.  We updated the MacBook to Sierra, NOT High Sierra, and everything started working again.  If you have downloaded Sierra before, and do not want to update to High Sierra just yet, log-in to the App Store, click the "Purchased" tab and scroll down to find Sierra, download and install. Depending where you are it could take a while, but after the install your MacBook and Apple TV play nice again.
