Whether you're attracted to open source software for its philosophy or its low price tag, you can find a capable and free image editor for doing everything from retouching digital photos to creating original sketches and vector illustrations.
These five mature open source image editors are fit for serious use.of 04
The trend of open source software is growing on Mac, and there’s no shortage of quality apps. You might be familiar with some common ones, like VLC, Firefox, LibreOffice, Handbrake, and more.GIMPWhat We Like
*
Powerful software that doesn't crash.
*
Easily handles Photoshop-level image editing tasks.
*
Compatible with RAW images.What We Don't Like
*
Not intuitive to beginners.
*
It is overkill for someone with simple editing needs.
*
User documentation is difficult to understand.
GIMP is the most widely used of the full-featured image editors — sometimes referred to as Photoshop alternatives — available in the open source community. The GIMP interface may seem disorienting at first, especially if you’ve used Photoshop because each tool palette floats independently on the desktop.
Look closely, and you'll find a powerful and comprehensive range of image-editing features in GIMP, including photo adjustment, painting and drawing tools, and built-in plugins that include blur, distortions, lens effects, and many more options.
GIMP can be customized to more closely resemble Photoshop in several ways:
*Photoshop plug-inscan run in GIMP using another plug-in called PSPI.
*GIMP emulates Photoshop brushesand layer styles.
*The Photoshop interface layout can be emulated by downloading a modified version of GIMP called Gimphoto, which is based on an older version of GIMP.
Advanced users can automate GIMP actions using its built-in Script-Fu macro language or by installing support for Perl or Tcl programming languages.of 04Paint.NET v3.36What We Like
*
Easy to learn and use.
*
Supports layers, transparency, and plug-ins.
*
Handles most graphics and image editing needs.What We Don't Like
*
Not powerful enough to replace Photoshop.
*
Open-source version is more than 10 years old.
Remember MS Paint? Microsoft included its simple paint program with Windows all the way back to the original release of Windows 1.0. For many, the memories of using Paint are not good ones.
In 2004, the Paint.NET project aimed to create a better alternative to Paint. The software has evolved so much that it now stands alone as a feature-rich image editor.
Paint.NET supports some advanced image editing features, such as layers, color curves, and filter effects, plus the usual array of drawing tools and brushes.
Note that the version linked here, 3.36, is not the latest version of Paint.NET, but the last version of this software released primarily under an open source license. Although newer versions of Paint.NET are still free, the project is no longer open source.of 04InkscapeWhat We Like
*
Generates pro-level vector graphics comparable to Adobe Illustrator.
*
Powerful text capabilities.
*
Compatible with many file formats.What We Don't Like
*
Handles CMYK color awkwardly.
*
Processing is on the slow side.
Inkscape is an open source editor for vector graphic illustrations, comparable to Adobe Illustrator. Vector graphics are not based on a grid of pixels like the bitmap graphics used in GIMP and Photoshop. Instead, vector graphics consist of lines and polygons arranged into shapes.
Vector graphics are often used to design logos and models. They can be scaled and rendered at different resolutions with no loss of quality.
Inkscape supports the Scalable Vector Graphics standard as well as a comprehensive set of tools for transformations, complex paths, and high-resolution rendering.of 04KritaWhat We Like
*
Great tool for digital painting.
*
Outstanding brush collection.
*
Animation tool kit.What We Don't Like
*
No support for pressure sensitivity.
*
Isn't as feature-packed as GIMP or Photoshop.
Swedish for the word 'crayon,' Krita is bundled with the KOffice productivity suite for most desktop Linux distributions. Krita can be used for basic photo editing, but its primary strength is creating and editing original artwork such as paintings and illustrations.
Supporting both bitmap and vector images, Krita sports an especially rich set of painting tools that simulate color blends and brush pressures particularly well-suited to illustrative artwork.

Here’s a list of some less popular open-source Mac apps you should try. You may be surprised by how useful they can be.1. IINA
IINA is a modern audio and video player for Mac. It has an entirely new design and supports Force Touch, the Touch Bar, and picture-in-picture. When you open a video, it automatically adds other videos in that folder to a playlist. If you’re listening to an audiobook or podcast, then IINA lets you quickly navigate between MP3 chapters.

One of the best features of Cyberduck is the integration with Cryptomator. It works by creating a vault directory in the cloud storage and encrypts files and folders with AES-256 cipher keys. Anything you put inside this vault will encrypt transparently.
That means no hidden backdoors from third parties, and greater privacy when using cloud services. The app is easy to use. All you have to do is create a new vault and enter a name and passphrase to secure it.

Most Mac users know that Cmd + W key closes a window or tab, while the Cmd + Q quits the entire app. The problem is that since those keys are near each other, it’s easy to quit an app by mistake.
This app adds a delay to Cmd + Q to prevent accidental closures. When you press Cmd + Q, a countdown overlay will appear above the current window. This puts the quit action on hold until the countdown completes. You can increase the delay from one second to, say, five seconds with this Terminal command (the time is in milliseconds):

It also lets you split the window into two halves, so you can keep one window for reference while you work in another. If you work with a lot of text, this is a handy app to have.

KeePass is a popular password manager for Windows. Unfortunately, it’s not available for macOS. One Mac alternative is KeePassX, but it rarely gets updated. KeePassXC is a community fork of KeePassX and the best way to use this tool on your Mac.
KeePassXC uses the KDBX password database format. That means you can share your database with KeePass without worrying about compatibility issues. It also natively integrates with any browser.

You can organize passwords into different groups, plus it has a password generator that allows you to generate long and secure passwords. By default, the app will lock after 30 seconds, but you can increase that duration. When you copy a password, the clipboard will clear itself after 10 seconds for security.

Longtime Mac users have likely seen an annoying error message that a particular file, process, or port is in use. For example, you can’t unmount a disk because some unspecified files are in use. This type of error is difficult to troubleshoot.
The lsof Terminal command lists all open files, processes, directories, devices, and more on your device. But using this command is tough. That’s where this app can pitch in.
Sloth offers a GUI built on top of lsof with additional useful features. You can filter the output, kill a file’s owner process, display file info, and more. This makes it easier to inspect what apps are using which files and sockets.

Apple’s keyboard (aside from MacBook Pro models with the Touch Bar) has a row of function keys at the top. These keys perform dual functions; as well as shortcuts like changing your screen brightness and volume, they can also act as standard function keys. The Fn modifier key adjusts this behavior.
Fluor lets you change the behavior of the function keys on a per-app basis. It detects the active app and changes the behavior of the keys in the background. In the app, the circle icon represents the default option. The sun icon is for the key’s shortcut, whereas the Fn button acts as standard function keys (F1, F2, etc.).

Karabiner-Elements lets you remap the entire keyboard. You can remap a single function key or make complex modifications. If you switch between Windows and macOS often, this app will help you create a consistent experience.
Some rules are available for download, so you get a feel for the capabilities of this app. I use it to assign complex modifier keys to a single function key and media keys to different functions. The app also lets you set up profiles or create rules for input devices.
