Java is not the only runtime that malware developers use to target victims of their attacks, and yesterday Adobe released an update to Flash that fixes two zero-day exploits in its popular Web plug-in software.

The two vulnerabilities in question affect both OS X and Windows systems, and allow malicious Flash content on Web sites to deliver malware to Macintosh systems via Firefox and Safari. The second vulnerability targets Windows users by tricking them into opening an e-mail attachment that contains the Flash-based exploit.

These problems are considered critical, so if you have Flash enabled on your system (which most … Read more

Apple's AirPlay feature is a convenient technology for sending audio to various devices. If you are on the same wireless network as the device then it will be available to your Mac, iPhone, or iPad to play music via iTunes, or even be used as a general audio appliance for system sounds.

In general, AirPlay devices are hardware accessories like routers such as Apple's AirPort, or media appliances like the AppleTV. However, if you are not willing to shell out about $100 or more for a new AirPlay and you have an old Mac lying around (especially a … Read more

Tabbed browsing is one of the more useful features to make it to Web browsers. However, as with using single windows you might inadvertently close one and need to restore it. While you can create a new tab and then peruse the browser history to find a link to the content it contained, an easier option is to use the built-in tab restoration options in your browser.

To do this, there are two hotkeys to keep in mind. The first is the classic Command-Z for undoing an action, which in Safari will undo a recently closed tab in a specific … Read more

In Mountain Lion, Apple split off its reminder options from the provided calendar program and put them into a separate program similar to the Reminders app in iOS. This program lets you keep track of your projects, routines, or what have you, with to-do lists for each. As you make progress, you just mark each reminder as completed, and it drops off of its respective list.

But if, say, you inadvertently mark the wrong reminder as completed, don't worry, you can still get it back.

The Reminders program does have a Completed section that you can click to see … Read more

Apple's autosave and resume features in OS X offer a great way to preserve your workflow if a program crashes or you simply need to quit it. However, these features do somewhat depend on the system's display output being constant, and may have some problems if you regularly change the system's display format.

If you use a MacBook system and plug in external monitors or if you regularly change display resolutions, then you might find certain programs (particularly Apple's TextEdit) will sometimes gather all windows into a collapsed group at some location on your display. This … Read more

The OS X Terminal is a very powerful tool for configuring and using a Mac, and can be used to script and program a number of aspects of the computer's operations; however, its text-based interface can be a bit of a cryptic environment to first-timers, especially when it comes to finding out what you can use it for.

There are thousands of Terminal commands available, but when you first launch it you might not have a clue where to look for them. Of course there are basic commands like "ls" for listing directory contents or "cd&… Read more

Before it was revealed, the file URL error in OS X was a fairly obscure and benign bug, and perhaps still is for the most part; however, since learning about it, a number of people have tried it out on their systems to have some fun, only to find that in some instances the bug may stick and perpetually crash a particular program.

While it is known that the offending string that triggers the bug will be saved in crash logs, which in turn can crash the Crash Reporter and Console applications, it may also be saved in a program'… Read more

The Next Web has uncovered a bug in OS X that will crash the current application almost every time if invoked. Reportedly, in applications that support text entry fields, if you type the text "File:" followed by three forward slashes in the field to indicate a file address, then the program being used will freeze and then quit.

The bug is a problem in a core system service called Data Detectors that is responsible for handling dates and locations, part of which is a checking routine for an entered URL address. When you type information into programs that … Read more

Following another recent security issue with Java, Apple issued an update that added the latest versions to the system's browser plug-in blacklist to protect users from any potential threats; however, in doing so it silently blocked a number of people from accessing required Java content, such as banking and financial Web sites.

To manage this problem, if you need Java, then the latest version from Oracle (version 1.7.0_13) that was released yesterday should have addressed the security holes and get your system back up and running. You can download it for OS X Lion or Mountain Lion … Read more
