Hi all, I'm debating doing a clean install of El Cap tomorrow, and I'm also debating turning on Filevault. Maybe someone can help me with these small questions before I do that: 1: Will it slow down my SSD a lot? I hear people say 'not much’ everywhere, but, if were talking percentages... Anybody know that? 2: I have Dropbox installed on my two Mac's. Will the files in Dropbox change as a result of turning on Filevault? And do I need to turn on Filevault on my second mac also? So that the systems with Dropbox in between are similar? And will the files on Dropbox servers be encrypted as well? 3: If I backup a Filevault protected folder of Macintosh HD to an external disc. Will that be encrypted on that external disc? Or Do I need to turn on Filevault on the Disc as well? If someone could shed a bit of light on this I'd be very very happy, Thanks!
