REBOL 2.7.7 SDK for OS X Intel
The 2.7.7 SDK for Mac OS X Intel has been released.
How does it work? It's successfully built and runs AltME, a fairly large REBOL/View commercial application that uses many functions, including networking and graphics. So far, so good.
I should note that OS X SDK is a product we intend to sell (rather than give it away) and it helps fund REBOL development projects. If you're using it for company projects or products, it's quite affordable! If you're doing work for non-profit organizations or informal groups and you will help promote REBOL in some real way, send us a feedback to let us know, and we may be able to help you.
