Former hobbyist/user of Carrara on MacOS. Great program, a lot easier to get started with than Blender (!). Am discovering many things that Blender can do that Carrara never could, but there remain plenty of features that it had that are not available in Blender. Alas, Carrara hasn't been updated or supported in like 12+ years and no longer runs properly under the current MacOS, so I had no choice but to find another modeling app.
