If you have further questions please post in the forum appropriate to your particular hardware or operating system. The following seeks to offer some guidance on the main security threats and how to avoid them. No computer system is completely immune from possible attack, but Apple’s OS X (being Unix-based) is less vulnerable than most, particularly the latest versions from Lion onwards. DON’T PANIC! But be aware that the Internet is riddled with potential threats to the security and well-being of your Mac or iOS device.
