The Week in Mac Apps: Disk Diet slims down your hard drive

In this week’s roundup of new Mac apps, we bring you a cure for bloated storage, a number of tools to maximize the value of your desktop, a solution to all your geometric problems, and much more.

If your hard drive is starting to feel a little tight around the midriff, Tunabelly Software’s $4 Disk Diet ( Mac App Store Link) can help you get it back into shape.

The app analyzes the contents of your drive, looking for files that can be safely removed to save space without losing any important data. Once the app has done its magic, a simple click immediately erases all the dead weight, leaving you with a lighter (and probably faster) system.

The Alchemist Guild’s $5 DockShelf ( Mac App Store Link) is a handy little utility that allows you to create additional docks for your desktop.

The app places docks on the sides of your screen, and lets you customize their contents to your heart’s desire, adding links to images, documents, apps, and websites anywhere you like.

Geometry is hard, but the International GeoGebra Institute’s GeoGebra 5 ( Mac App Store Link) makes it a little easier to digest.

Designed for educational needs of all levels, the app helps you understand and visualize all sorts of geometric problems, from complex formulas to observational diagrams.

In case you missed it, Apple has updated Pages ( Mac App Store Link), Numbers ( Mac App Store Link), and Keynote ( Mac App Store Link) so that they can take advantage of new features in OS X El Capitan.

All the apps now support split-view fullscreen multitasking, and come with a variety of improvements and bug fixes, including the ability to open and edit documents originally saved using legacy versions of Apple’s office suite.

Mach Software Design’s $3 Mach Desktop ( Mac App Store Link) brings beautiful high-definition dynamic wallpapers to your Mac.

The app displays great sceneries rendered in realtime alongside several panels full of useful information like the weather, time and date, and more.

Innoveghtive’s $5 Magpie is now compatible with OS X El Capitan.

Magpie is a handy utility that lets you quickly capture a video from any webpage and play it later at your convenience. The app supports most popular formats, keeps a history of the videos you’ve watched, and saves its data in iCloud, which allows you to sync and watch your files on all your devices.

Editing hex files may seem like an esoteric problem in today’s world, but if you need to do it, Andreas Pehnack’s $40 Synalyze It! Pro ( Mac App Store Link) has got you covered.

The app offers a number of advanced features, including the ability to map data to one of many known file formats, color-code various data elements, and perform advanced search-and-replace capabilities.

Catalystwo’s $17 Tab Notes lets you create text notes and attach them to the edge of your screen.

The app sits quietly in the background and creates a “hot zone” at the bottom of your screen: Click there, and you can create and edit those notes—which will then be anchored to the edge of your desktop. You can even assign each of them its own cute animal icon as an easy way to tell it apart from the others.

Developer Daniel Alm’s $25 Timing ( Mac App Store Link) tracks all the time you spend at your Mac using an ingenious—and completely automatic—method.

The app simply monitors the software you use while you’re at your computer and then lets you review the day’s activities so that you can both keep tabs on your work habits and fill your timesheets whenever you need to.
