Leaves X11 Window behind
The developers of GIMP have, for the first time, released a native Mac version of the software. While the app has been available to Mac users for some time, previous versions required users to load it under the X11 Window environment, making it inconvenient. All releases as of v2.8.2 should have a DMG installer file available.
GIMP is a multiplatform, freeware alternative to apps like Adobe Photoshop. The software sports a customizable interface, and features such as perspective correction, extendable format support, and tablet, USB, and MIDI controller input. Aside from the Mac, editions are available for Windows, GNU/Linux, OpenSolaris, and FreeBSD.
