The GIMP is one of those programs that's either loved or hated by Mac users. Loved by many because it provides the power and functionality of Photoshop for free but hated by others because they find it difficult and awkward to use compared to Photoshop. I've already looked at one way of making The GIMP feel more like using Photoshop but what about if you just want something GIMP-like but simpler?
SeaShore has been developed as a simpler, easier to use photo editor based on GIMP. It's still free to use and features gradients, textures and anti-aliasing for both text and brush strokes. It also supports multiple layers, alpha channel editing and uses the same native file format as GIMP. And due to Cocoa, it sports a much slicker OS X friendly user interface that definitely looks better than The GIMP for Mac.
The downside of this however is that its not as powerful as GIMP and lacks certain advanced editing features. In fact, even basic features such as Color Balance and Levels are missing from SeaShore. Stability can also occasionally be an issue as the SeaShore forum illustrates but it usually manages to carry out most functions without any problems.
SeaShore feels a lot less intimidating than GIMP though and both the slick Cocoa interface and simple functionality will make it popular with anyone who has struggled with GIMP.
