1. App Cleaner

AppCleaner is a small application that allows you to thoroughly uninstall unwanted apps. Installing an application distributes many files throughout your system using space of your hard drive. When you uninstall these apps, many of these bits and pieces are left on your hard drive, needlessly taking up space.  AppCleaner finds all these small files and safely deletes them. Simply drag and drop an application onto the AppCleaner window. It automatically finds all the related files specific to that app and adds them to the AppCleaner window for you to review. You then have the option of deleting all the files, or keeping the ones you think you may need at a later stage, should you reinstall the app. You then simply click the delete button. No more orphan files on your disk!

2. Monolingual

Monolingual is a program for removing unnecessary language files from Mac OS X, in order to reclaim several hundred megabytes of disk space. As designers, we usually have huge files which can very quickly eat away at your hard drive space so getting rid of any superfluous files is sometimes very necessary. Having a fair amount of freed-up space on your hard drive for Photoshop to use as a scratch disk will help you work on your files will less drag, especially if your RAM is limited. If you’re running out of hard drive space, this is the app for you.

3. Quicksliver

Quicksilver is an application that lets you reach any program, folder or file in a few keystrokes and is aimed at increasing user efficiency. It allows you to use the keyboard to promptly do things like launch applications, manipulate files and data, run scripts, or send email. You don’t have to go searching through your files to find something and you don’t have to worry about how your folders are arranged. You can customize its search options to include your address book, iTunes, and recent email addresses. Set this application to load at start up then customize a quick launch key so it can be at your fingers when you need it. This is the fastest way to find files and open applications.

4.  Growl

Growl is a notification system for Mac OS X. It allows applications that support Growl to send you notifications so you know what’s happening on your computer at all times. Growl installs itself as a preference pane and is added to the Mac OS X System Preferences. Users are able to fully control notifications by going to this pane. Here the interface will allow you to enable and disable Growl’s notifications for certain applications in their entirety, or select specific notifications for each application. The display options of the notifications can also be fully customized from small non-intrusive floating icons in the corner of your screen, to larger ones with sound.

5.  Teleport

Teleport lets you use a single mouse and keyboard to control several Macs. It allows you to synchronize your pasteboard between computers (and limit the size of the pasteboard if you wish), so you can cut from one computer and paste in another. It also allows you to transfer files by simply dragging them from one Mac to another (although this tends to work better with smaller files).

Teleport will need to be installed on all Macs you wish to link up. After installing you can find the program in the System Preferences pane. You will need open up two ports on your firewall they will be saved as “trusted hosts” under the security settings.

6. OnyX

OnyX is a multifunction utility for Mac OS X (PowerPC and Intel). It allows you to verify the Startup Disk and the structure of its system files; to run miscellaneous tasks of system maintenance; to configure the hidden parameters of the Finder, Dock and of some of Apple’s own applications; to delete caches; to remove a certain number of files and folders that may become cumbersome and much more…
