Hi all forum users, I have clean installed new OS X Mavericks. When its finished, total space used was 12GB ( which is kinda weird, cause I read on here, and it normally takes up 8-10GB), I did not install any other applications or whatsoever. After 2 days, my DiskUtility shows that 16.5GB is occupied already. I did not download ANYTHING, except AdobeFash player. So where did 4.5GB came from???? I am using internet in hotel, so I am worried if someone is using my mac somehow ( hacked into it distantly? ).... What can be the cause?
