I get this error message when I try to install… “2021_DirectLink-SketchUp_Twinmotion_SU17-21_2020.75.5530.51_setup.pkg” can’t be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information."
I also tried installing an earlier version of the Direct Link Plug-in, but it does not support SketchUp Pro 2021.
