App Won't Start

[IridescentShadow]

When attempting to launch the app it quits immediately every single time. This was logged to system.log during a failed launch attempt:

Oct 10 16:11:29 com.apple.xpc.launchd[1] (com.apple.xpc.launchd.oneshot.0x10000033.Radiant Player[15762]): Service exited due to signal: Killed: 9 sent by CoreServicesUIAgent[15728]

I am running OS X 10.12.6.

I tried upgrading to High Sierra (10.13), but the issue persists. Similar error message in console:

Oct 16 12:29:55 com.apple.xpc.launchd[1] (com.apple.xpc.launchd.oneshot.0x1000000a.Radiant Player[12850]): Service exited due to signal: Killed: 9 sent by CoreServicesUIAgent[10973]

Are there any more lines in your logs? Various sources on the internet are saying that Service exited due to signal: Killed: 9 sent by CoreServicesUIAgent essentially means "died unexpectedly" and the lines in the logs preceding it should have the actual crash information.

Had the same problem. Have you allowed the application accessibility privileges?
System Preferences --> Security & Privacy --> Accessibility --> Allow Radiant Player (Check the box)
