Inkscape for Mac allows you to create vector-based drawings using advanced features like path editors and object sculpting. This open-source product is not native to modern Macs and requires X11 to be installed on your system. On a more positive note, the app comes with documentation that is very detailed and easy to follow.
Detailed documentation: We were impressed by the detailed documentation for Inkscape for Mac. It walks you through every feature along with practical examples and screenshots to help you learn more effortlessly.
A large array of features: The software lets you create vector drawings using a grid that you can snap objects to and various object creation tools like polygons, circles, squares, etc. You can also sculpt objects and create paths that your objects should follow.
Multiple format support: The software's default format is SVG, which is very robust and has advanced capabilities like creating animated images. Other supported formats include JPEG, PNG, BMP, TIFF, EPS, Postscript, etc.
X11 required: Since the software was built a long time ago, it requires additional software called X11 that no longer ships with OS X. The software is free of charge and can be downloaded separately by opening the X11 app on your Mac.
Outdated interface: If you're already used to drawing tools like Illustrator or Photoshop, you will find the app a bit odd since various features are not where you expect them to be. For example, the layers are located on the status bar and are presented in a dropdown menu. To make matters even worse, you cannot rearrange your toolbars.
Unintuitive shortcuts: Inkscape for Mac comes with keyboard shortcuts that employ the Control button as the main trigger and will go against the muscle memory of everyone who is used to Mac keyboard shortcuts. Fortunately you can change the shortcuts from the app's preferences.
Despite its age, Inkscape for Mac still functions well and lets you produce usable content once you get comfortable with the interface and the available features. While products like Adobe Illustrator are much more professional and powerful, you don't have to pay a dime for this open-source offering, and the included guide can get you up to speed rather quickly.
