It can be beneficial to clear out those taking up the significant space in your /Library/Caches/ if you need to free some up, but you really shouldn't clear any contents of your /System/Caches unless there is a problem.

The MacPorts Project Official Homepage

The MacPorts Project is an open-source community initiative to design an easy-to-use system for compiling, installing, and upgrading either command-line, X11 or Aqua based open-source software on the Mac operating system. To that end we provide the command-line driven MacPorts software package under a 3-Clause BSD License, and through it easy access to thousands of ports that greatly simplify the task of compiling and installing open-source software on your Mac.

We provide a single software tree that attempts to track the latest release of every software title (port) we distribute, without splitting them into “stable” Vs. “unstable” branches, targeting mainly macOS High Sierra v10.13 and later (including macOS Big Sur v11). There are thousands of ports in our tree, distributed among different categories, and more are being added on a regular basis.

Getting started

For information on installing MacPorts please see the installation section of this site and explore the myriad of download options we provide and our base system requirements.

If you run into any problems installing and/or using MacPorts we also have many options to help you, depending on how you wish to get get in touch with us. Other important help resources are our online documentation, A.K.A The MacPorts Guide, and our Trac Wiki server & bug tracker.

Getting involved: Students

A good way for students to get involved is through the Google Summer of Code. GSoC is a program to encourage students' participation in Open Source development and offers a stipend to work on the project with an organization for three months. MacPorts has been participating in the program since 2007! We shall participate next year as well. You may find past GSoC projects here.

We have a list of ideas with possible tasks for MacPorts and additional information about the process at wiki/SummerOfCode. We are always open to new ideas. Research on the idea, draft an initial proposal and get it reviewed.

Getting involved

There are many ways you can get involved with MacPorts and peer users, system administrators & developers alike. Browse over to the “Contact Us” section of our site and:

• Explore our mailing lists, either if it is for some general user support or to keep on top of the latest MacPorts developments and commits to our software repository.
• Check out our Support & Development portal for some bug reporting and live tutorials through the integrated Wiki server.
• Or simply come join us for a friendly IRC chat if you wish for more direct contact with the people behind it all.

If on the other hand you are interested in joining The MacPorts Project in any way, then don't hesitate to contact the project's management team, “PortMgr”, to explain your particular interest and present a formal application. We're always looking for more helping hands that can extend and improve our ports tree and documentation, or take MacPorts itself beyond its current limitations and into new areas of the vast software packaging field. We're eager to hear from you!

Our Verdict

The free, open-source Calibre is an e-book manager, e-book creator, and desktop e-book reader. It’s also a must-have tool for any bibliophile with an e-reader and a growing library. Calibre is compatible with devices from 15 e-reader manufacturers—including Amazon, Android, Apple, and Barnes & Noble—and the developers are quick to update the application when new e-readers are released.

Most e-readers automatically place you in their little ecosystems, with built-in book syncing, managing, and purchasing set-ups. Calibre steps in and gives the readers control over their libraries in a few ways. First, it manages your collection of e-books in a library that is sortable by author, series, format, and publisher, as well as other metadata. It’s also searchable by tags and comments. If your books are missing their covers or any metadata, Calibre will download the information from the Internet. The application can sync the library with your device when you connect to your computer. If syncing is too wired for your tastes, store your books on Calibre’s Web server and download them from any device with a browser and Internet connection.

Macos Calibri

The other half of Calibre’s powers are devoted to formatting content for your device. Converting common file types into the format supported by your e-reader is easy, and Calibre supports a large variety of both input and output formats. Want to read an HTML document on your Nook? Convert it with Calibre. Since reading isn’t a books-only activity, you can configure the application to format news in the best format for you device. It can even deliver full-length news articles from RSS feeds and publications like the New York Times, The Economist, and Macworld. Currently, Calibre is compatible with over 300 news outlets.

A final, unsung use for Calibre is as a desktop e-book reader. So far, mobile devices have monopolized the booming e-book market, with Apple going so far as to only make its iBookstore available to iOS devices. Calibre will open any e-book file in a clean, distraction-free window on your computer for an enjoyable reading experience outside of a mobile device.

The interface looks bright and user-friendly, but it can take some time to learn all of the many functions and menus. It’s understandable given the variety of tools this program is packing.
