I recently decided to try some new Torrent clients, I downloaded the BitLord and then everything started to go wrong. I quickly noticed it was installing unwanted and unchecked bundle apps, then I tried my best to remove all of them. But now, this border is not going away anytime soon. I tried to enable VoiceOver then disable it, not working. I even dig into the VoiceOver Utility hoped I can find some options would fix this. I tried to restart the system into Safe Mode, and the border was still there. I even tried to perform a Repair Disk Permission and Verify Startup Disk with CleanMyMac 3. None of the above worked.
Can you please tell me how to get rid of it, its not causing any trouble, but I just find it irritating. I think wipe out the system and reinstall macOS would get me there, and I do have a TimeMachine backup that backups itself every 2 hrs. But I'm afraid when I use Migration Assistant this border will be carried with the old backup.
I'm running macOS 10.12.3 (16D32).
Best Regards.
