Hey I know Im a month late and Im not sure if someone has mentioned this yet, but Mac actually has a way to bypass this. What works for me is to right click on the app and then click open. For some reason after doing this your Mac should register it as safe and you can use it normally. Also be sure to check in System Preferences > Security and check to see if there is some kind of "allow access" checkbox at the bottom, make sure it is checked, and that should do the trick :)
