I just downloaded this and I use a Mac with 10.17 and I cant open the rack because I keep getting the message that the rack is damaged. does anyone know what to do with this?
10.17? Are you from the future? 10.15 is latest version (Catalina) no?
It sounds like you have a permissions issue. First thing to try is go to System Preferences > Security & Privacy > General Tab and make sure you have “Allow apps downloaded from” set to “App Store and Identified Developers” (not just App Store)
This is such a common issue I would have thought it would be in the manual, but it if is I can’t find it.
