The necessity of regular use of the 'purge' command in OS X

When using your Mac, active programs, documents, and system resources will be loaded into memory (RAM), where they can be accessed quickly to run and perform computations. While active memory contents are maintained in memory, the system also keeps some recently used but inactive processes and data there in order to quickly revive them, if needed.

These memory allotments should be managed dynamically for optimum performance, but some people who regularly run low on RAM may be concerned about this and resort to using "RAM cleaning" programs. One of these is the "purge" Terminal command that … Read more

How to recover your iTunes account ID

If you have regularly used iTunes to purchase music and movies, then you may have a significant collection of titles that are tied to your specific iTunes account. However, if you have used more than one iTunes account, then you may run into trouble if you cannot remember the account ID you used to purchase the items.

At the very least, if the songs are DRM-protected and you have not authorized your system to play them, then iTunes will present you with a notice to log in to your account before it will play them.

Insignificant bug keeps encrypted disks unlocked after ejecting in OS X

Apple's CoreStorage disk encryption technology has a small bug that will keep a disk unlocked, even after it has been ejected from the system.

In OS X Lion, Apple introduced a drive management technology called CoreStorage. When enabled, CoreStorage will create a "logical volume group" out of one or more physical drive partitions, and then create usable "logical volumes" from this group to serve as storage for your system. This setup allows the logical volume to span multiple physical partitions (as is seen with Apple's Fusion Drive), and support features like encryption for Apple'… Read more

Bookmark files and folders in Safari

If you are a Safari user then you might be familiar with the program's Bookmarks bar, where you can save links to individual Web pages, or group them as collections in folders.

You can also use it to save any other location you can link to through Safari's address bar, including files and folders on the system.

To do this, simply drag a file to the address bar, and you should see a bookmark to it as you would any other file. You can also load some files such as images directly into Safari by dropping them on … Read more

Options for secure file removal in the OS X Terminal

While deleting files in OS X simply involves moving them to the trash and emptying it, this routine does not remove the data of these items, but instead only clears the directory entry for them. The content of the items is kept on disk with the system having no way to access it; as a result, there is potential for the content to be scanned and recovered by data recovery tools.

To prevent this from happening, you can use secure-erase features in OS X, one of which is to securely delete the files in the Finder by choosing this option … Read more

iFixit tears down the new AirPort Extreme

iFixIt took a look at the guts of the new MacBook Air, as well as the new AirPort Extreme base station, which Apple unveiled at WWDC 2013. The new AirPort Extreme offers more advancements in speed, connectivity, and capacity than its predecessors and has a new design, to boot.

This new design has spurred … Read more

Microsoft patches critical vulnerability in Office 2011 for Mac

Microsoft has issued an update to Office 2011 for OS X, which closes a critical vulnerability that may allow remote code execution from an attacker.

With this vulnerability a maliciously crafted Word document or e-mail message in Outlook (with Word configured as the e-mail reader) could give an attacker the execution rights as the current user, allowing them to arbitrarily run code on the affected system.

While this update is a run-of-the-mill closure of identified vulnerabilities, be sure to keep your system fully updated. While there are undoubtedly other undocumented vulnerabilities in software, malware developers often use known and patched … Read more
