Download the teachit_app.tar.xz file via the link and unpack it. Some symbol with the TeachIt Log will appear in finder. Most likely MacOS will refuse to execute the app because it is not trusted.
Open the Security Console: https://support.apple.com/en-us/HT202491 and click on the Lock. Now click on the TeachIt Icon again and you should see in the security console window a question whether you want to trust TeachIt. Click yes (we are trustworthy!). TeachIt should start. Close the lock in the security console. Close TeachIt and open it again. It should open with no questions asked.
Optionally move the TeachIt App to the Applications folder.
