OS X supports a number of different languages, and either during installation or in the system preferences you can choose your default language in which to have the system display localized elements such as menu text and dialogue text. In addition to interface elements, Apple supports localization on some system files and folders, including the default folders in the home directory. This means that if you switch your system's language, the names Desktop, Movies, Pictures, Documents, and so on that are in your home directory should also be shown in the new language.

While this works for most people, … Read more

While rare, sometimes after updating OS X either with an upgrade or with an intermediate patch users have found that an account on the system may no longer be accessible. This may be because the system refuses to accept an account password, or because the account no longer appears. While such problems may have you initially consider reinstalling OS X and restoring from a backup, you may be able to fix the problem without doing this.

Missing accounts after an update Local account information is stored in the system's directory database (located in the hidden /var/db/local/ folder), … Read more

This awkwardly named utility (now known as "Better Rename" in the Mac App Store) can be extremely useful in some very specific situations. Anyone who needs to rename large batches of files on a daily basis--especially Web developers and anybody working with lots of photos or audio files--should definitely check out A Better Finder Rename. Most of what this app does can also be done with the Finder and Automator, but nowhere near as quickly nor as easily.

ABFR offers a huge number of renaming options, everything from modifying text and adding sequence numbers to changing formats and … Read more

Dropbox is a free and extremely easy-to-use tool for sharing files and syncing them between computers, and you can also use Dropbox to back up files and access them from other computers and devices (including from your iPad or iPhone, with dedicated apps for each of those devices).

Dropbox's interface is largely invisible, which is part of what makes this app so easy to use. When you install Dropbox on your Mac or Windows machine, you create a Dropbox folder. This is a local folder that lives on your desktop, but you can access the folder from other computers (… Read more

There are plenty of downloadable defrag utilities to choose from, but it's hard to beat the ease of use and helpful extras in IOBit's Smart Defrag.

With this utility you can quickly analyze your hard drive to check the level of defragmentation before committing to a scan. The interface shows you different colored blocks representing fragmented files, frequently used files, and more, with a helpful key to show what each colored block represents.

When you're ready to pull the trigger, you can choose from a straight defragmentation (fastest), or have Smart Defrag perform either a fast or &… Read more

How many empty folders are in your system? Leftovers from uninstalled programs, temporary folders that moved in to stay. Wouldn't it be great if someone wrote a simple tool that finds and deletes all that junk? Someone did: Fast Empty Folder Finder scans folders, directories, and entire drives for empty folders, displays them in a list with previews, and deletes those you select.

At 111.5KB, Fast Empty Folder Finder is compact, and since it's also portable freeware, it requires no installation but runs as soon as you click its executable file. It has a very simple but … Read more

The user's home folder in OS X contains a number of default directories including the Documents, Downloads, Desktop, Library, Movies, Music, and Pictures folders. While these locations do not have to be used to store your files, even if you rarely use these folders to store your files we recommend you do not rename or remove them.

OS X should have default permissions settings on these folders that prevent them from being inadvertently renamed; however, if you migrate your system, restore it from backup, or purposefully change permissions, then this restriction might change and allow you to rename the … Read more

In the classic Mac OS, colon characters were used to separate folders in a file path, but in Unix-based systems the folder separator is a forward slash character. These characters are prevented from being used in file names because it would confuse the system when trying to access the file. When Apple developed OS X, the use of the forward slash was adopted because of its Unix underpinnings, so in OS X you cannot include a true forward slash in a file name.

This may cause some confusion, since in the Finder you can rename files to include a forward … Read more

Data Rescue can help you retrieve lost files, whether they were destroyed in a hard-drive crash or just accidentally deleted by some overzealous trash-emptying.

This app has an easy--and even kind of fun--interface, with 3D animations that show available drives and your options for diagnosis and recovery. Once you've chosen a drive to examine, Data Rescue prompts you for an additional drive to use as "workspace" and gives you six choices: a Quick Scan or Deep Scan to find recoverable files; a Deleted Files Scan (good for an accidental deletion on an otherwise healthy drive); Clone, which … Read more
