@ieure I have been using macOS since System 7 days… while Apple did start to be a little more circumspect about running randomly downloaded applications, I have never not been able to run anything. “Open” *is* the same as double clicking.
If it says it is “damaged” it’s because of an actual problem or inconsistency with the program, not some sort of conspiracy.
@chris @ieure Open is *not* the same as double clicking, Open will give an “are you sure” dialogue in cases where double clicking will directly reject it.
