MacBook Pro mid2014 retina. Not done a major OS shift on this machine & am uncertain about how it will mess with my file system or any data as well as apps. I've read about the High Sierra buggy bug fix which sounds horrifying & have felt safer staying with Yosemite but I'm aware Yosemite is (I think) end of life so no more updates...I use Norton & VPN (PIA) regularly but am getting nagged to upgrade. Am conversant in some things tech but assume I'm not in your answer, thanks!
