It can easily be disabled or overridden by the user.It has, however, the same limitations as XProtect, and in addition the following: Gatekeeper doesn't depend on a database of known malware. That may not mean much if the developer lives in a country with a weak legal system (see below.) His identity is known to Apple, so he could be held legally responsible if he distributed malware. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated ' Software installed from a CD or other media is not checked.ģ. It only applies to software downloaded from the network.It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.Still apply caution to your actions online and elsewhere, and be wary of offers, unknown files, popup windows, and random update warnings (especially through email or Web pages). Therefore, do not assume that with one installed you will be able to freely open any file you find and be safe. They will help detect known threats if you encounter them but are not guarantees of full protection. However, despite claims here and elsewhere of problems with their software installations, most anti-malware tools work just fine for those who have installed them, and reside benignly in the background, scanning and doing their thing.Īlso keep in mind that anti-malware tools are just helpers. Of course any additional software you add to your system may adversely affect it, so often anti-malware tools are seen as unnecessary because of the potential for being intrusive without much benefit in return, given the relatively low level of malware that targets OS X. If you are uncertain of what to look for, and would feel more comfortable having a tool help you scan for and identify malware, then I'd recommend installing a lightweight and free malware scanner like Sophos Home Edition ( ition.aspx ). One of the best ways to protect your system is to develop computing 'street smarts' and know how to identify and avoid suspicious locations and files on the Web however, this takes time to develop. OS X includes a number of security measures to combat malware (Gatekeeper, XProtect, and a built-in Firewall) however, no system is completely foolproof.
