Also, it seems that the people that are not able to remove the permission with the command line got an alert on a prior app that said. Malware Blocked and Moved to Trash "Madshot360.app" was not opened because it contains malware. This action did not harm your Mac We were in the middle of changing certificates and there was/is no malware. Could this have caused their problem? The other people did not see this warning and also do not have a problem removing the permission.
