I made a completely clean install of Yosemite. I installed it on a separate partition and the install went fine. However, some "preferences" have been transferred and I don't know why. I did not restore from Time Machine and I am positive this is a separate partition. I do not have Chrome installed at all, and the old Safari is gone, obviously. It doesn't affect the overall experience, but it bugs me. Is there any way to reset it or remove it? Thanks.
