mac_sys_int v1.3 doesn't seem to work with macOS Catalina

[cfezequiel]

I tried running the System Integration v1.3 simulator on macOS v10.15.7 but it just generated the following error: "The application “sys_int” can’t be opened."

Did you fix it? I also had the same issue with you but I don't know how to open the Simulator on Mac. If you did, please tell me the instruction. Thank you so much!
