Alright so I couldn't reproduce much except ending Tenacity from MissionCenter does kill the GNOME Session somehow. I'll dig.
Other than that, Tenacity is behaving perfectly fine so I think we can eliminate the malware suspicion for them 😅
Altough it would be awesome to get those permissions in order. @tenacity Let me know if I can help!
Note that with something like htop the process might show under brwap.
