Acorn, a Mac-only image editor has just reached version 3.0, almost at the same time with Adobe’s mid-cycle refresh that doesn’t contain any updates to its popular photo editing app.

New in Acorn: Layer styles, Live Gradients, Quickmask, plus 50 more, a trial version is available for download from the website and they’re having a time-limited special on the Mac App Store.

They’re not joking when they said “Built for Human”, for it has the most humane UI design for a complex software of a robotic nature.
