Hello again to everyone on MacRumors. I love the new iMac which I brought recently, and have been having a good look round the system getting used to all its new weird and wonderful features. (The last OS I was using was Tiger, so I feel like I'm on an alien planet right now.) I've been looking for a good guide on how to configure ML's security settings, but was only able to find some guys, er, perhaps slightly paranoid thoughts: https://discussions.apple.com/docs/DOC-3291 and: http://mostlysecure.blogspot.co.uk/2012/09/hardening-mountain-lion.html Anyone got any other good links, or can suggest any other good guides? Or any other good tips per say? The first thing I'm trying to wrap my head round is the AppleID's new importance. It seems to me that the AppleID is required if you want to download anything from the app store (a new feature), and the Admin password is required if you want to install anything (a good old feature)? Is that correct? If that's the case, then would it make better security sense to create an email address which isn't given out publicly, and used only as an AppleID instead? Or is that what this whole @me thing is about (never understood that. Been under a rock for years. Apologies.) Moving on from that point: I've read that it's wise to create a non-admin account for daily usage. How do you do that, and have many people here done this? Also. Say you decided to switch on File Vault to encrypt your data: if you backed up said data and then transferred it to another machine, would you be able to read your data as normal, or would it be all scrambled? This is probably another one of my silly questions! ^_- Thanks a million to anyone who gets back to me. I'm always extremely interested in everyones views.
