Instructions for Mac are shown in red text on the download page:

"To start Chimera on 10.15 (Catalina) or later, you need to right-click (or alt-click) on the app icon and choose "Open" from the popup menu. This is only necessary the first time you use it. Thereafter it can be started normally."

There is a little more explanation in this previous post:

I hope this helps,
