OS manipulation by APPLE

[Airush77]

Hi,
recently I've been having various concerns with my O/S being manipulated. I ask the question can anyone provide advice on how these files got on my system without my consent or acknowledgement.... I've also check console log and a huge chuck of days are missing..?

That is the typical OS X Install package... Could it have automatically downloaded Mavericks/Yosemite/El Capitan/Sierra for you? Check in your Applications folder.
