I selected individual/free, because I want to get a sense of what this whole Unity thing does, and downloaded UnityHub, expanded the dmg file and dragged it into /Applications. On opening the app I get the following error message, and wonder how to get this stuff working. (I’ve been running Catalina betas for a while.) Thanks!
“Unity Hub” can’t be opened because Apple cannot check it for malicious software.
This software needs to be updated. Contact the developer for more information.
