Early this morning Apple issued an update to its XProtect malware-handling system in OS X that updates the Web plug-in blacklist to include a more recent version of Oracle's Java plug-in. The update now will prevent all versions of the Java Web plug-in before version 1.7.11.22 from running on the system (previously the limit was version 1.7.10.19).

This change was likely made because of a recent security issue in the prior version of the Java 7 runtime that affected JRE 7 Update 10 and earlier. A patch for this was issued by Oracle … Read more

Apple's Mac systems come with a basic audio controller for playing through the system's internal speakers or through the audio ports to headphones or a stereo system. However, if you would like to use a different controller such as a multi-channel USB interface for recording with GarageBand, Logic, or other use, then you can add it to the system and set it up to be used instead of Apple's controllers.

While useful to have, if you configure your system with multiple interfaces then you might run into an issue where the system could revert to its internal … Read more

Following recent security vulnerabilities in Java, malware developers are taking a new approach to exploit the Java platform by issuing false updates that pose as legitimate updates for the runtime.

The latest version of the Java runtime that fixes recent vulnerabilities is update 11, and Kaspersky labs is reporting that a new malware is out that poses as "Java Update 11." The malware is packaged in a Java archive file called "javaupdate11.jar" that contains two Windows-based executables called "up1.exe" and "up2.exe." When installed the programs open a back door … Read more

Lately Java has been getting a bit of bad press, thanks to several consecutive security holes that have been exploited by malware developers. One notable occurrence was the Flashback malware threat that affected a number of OS X users, which (though due in part to Apple's negligence about Java upkeep) was rooted in the Java runtime. More recently, Java 7 has seen a new zero-day vulnerability that has been circulating in exploit kits.

In response to these threats, many in the tech community have recommended that people uninstall Java altogether. However, this can be impractical for some, as many … Read more

One relatively long-standing issue that a number of Mac users have been experiencing is an apparent incompatibility with Citrix services that have been installed on their Macs by IT departments at work or school locations. If this occurs users may experience slow systems with poor battery life, and find that the Activity Monitor utility shows a service called AGAdminService taking up 100 percent of the system's CPU.

Citrix offers a number of virtualization and cloud-based storage options for various work environments, in which applications and services for accessing secure databases (such as for health records) run on a central … Read more

The latest versions of OS X integrate a number of personal data services that can be accessed by various applications. For example, if you have a Twitter account set up in OS X, you can then have various programs send tweets to this account or otherwise interact with it. Though convenient, this does need to be secured, so Apple invokes management of this service through a central privacy framework, which you can interact with both in the system preferences and in the command line.

When a program requests access to your personal data, the system will first present you with … Read more
