I've recently downloaded an app. I can confirm it worked in OS X El Capitan, but it doesn't open anymore in macOS. When opening the app, I basically get a pop-up saying that the app is not supported with my version of macOS. I can confirm it is not a PowerPC application. I tried opening the app via Terminal. When trying that, I get the following result.
; exit; objc: Objective-C garbage collection is no longer supported. Abort trap: 6 logout Saving session... ...copying shared history... ...saving history...truncating history files... ...completed. Deleting expired sessions...none found.
Is it still possible to open the app using another method? If not, could someone explain me why?
