In Short

Apple employs advanced security technology: Gatekeeper, for example, which makes it safer to download software for your Mac by making sure the developer passes muster. FileVault 2, which protects your Mac's data by using XTS-AES 128 encryption. iCloud Keychain, which stores unique, strong and encrypted passwords, making it easier for you to visit web sites that require you to log in. And sandboxing, a requirement of apps sold through the Mac App Store — isolating apps from critical system components, keeping your data safe.
