Back in July when we introduced 10.3.2, we added macOS 64-bit support to Delphi. We’ve expanded that support in 10.3.3 to include macOS Catalina. macOS Catalina is the first version of macOS that requires all apps to be 64-bit enabled. With our Delphi macOS 64-bit support, you can also target the macOS App Store, complete with notarization support.
