Hello, so I Build Ros2 Eloquent on my MacOs, as i wasn´t able to build at Mojave due to some 'you need to have MacOs 10.15' errors, I upgradet to Catalina and build again.

While I was able to get the the build complete and got the first 2 examples running I had some Error msgs which I don´t understand. Could someone explain to me what these means, if they are Critical and if I need to fix them?

The message was:

13 packages had stderr output: fastcdr orocos_kdl pendulum_control qt_gui_cpp ros1_bridge rttest rviz_common rviz_default_plugins rviz_rendering rviz_rendering_tests rviz_visual_testing_framework spdlog_vendor tlsf_cpp

You will need to share the actual stderr output of these packages shown above this summary line.

I Installed it Yesterday and don´t have the Terminal opened anymore. Any Idea how i could see it again?

I think most of these stderr are quite common when installing ROS2. The ros1_bridge for example will give an error when it can't find a ROS1 environment on the system and it will be skipped. This is because the ros1_bridge creates a bridge between ROS1 and ROS2 and needs both of these environments sourced when compiling. I can not give you any guarantees that the other stderrs you encountered are harmless (as Dirk said, you didn't post them so it is hard to help you there), but I expect they are (most packages appear to be related to visualization, tests and demos anyways).
