This version has been released by Apple.
Changes for Version 3.2.2 (Video Animator)
This release fixes compatibility issues that affects certain Macs having multiple GPUs.
Added support for Multiple GPU rendering (usable only on Mac Pros).
Improvements:
1) You can now use multiple render devices together for rendering.
Advice: Don’t select both CPU and GPU for rendering at the same time. It is substantially slower than using the GPU alone.
On the 2013 Mac Pros, select both GPUs, but not the CPU for rendering. This will give you roughly twice the render speed compared to using a single GPU.
2) Added “Force OpenCL program rebuild” as OpenCL troubleshooting tool to Render device selector and Preferences
3) Added Sampling Level statistics to render logs and Render State window
Some feel this is a better way to measure render progress
4) Added changes to KeyFrame window to allow duplicate keyframes
can drag and drop a keyframe in keyframes window to create duplicate
can edit the duplicated keyframes in Triangle editor and change them – useful for keyframe animation
5) Rendering progress dialogs are no longer auto-hidden when you switch to another app
Bug Fixes ====================
1) Fix for render device selection not working correctly on some multiple GPU Macs
2) Fix for Triangle Editor changes made to a specific keyframe that are not showing up in frames window and not being properly saved
This app update has been released to the Mac App Store by Apple.
Changes for Version 3.2.0 (Video Animator)
This primarily bug fix release emphasizes getting perfect quality fractals from GPU rendering.
Summary:
The render performance using the 2013 Mac Pro’s twin GPUs at the same time varied between roughly 20x and 28x faster than using its very good 6 core Intel Xeon CPU (using the Fractal Architect 3D OpenCL CPU renderer).
When restricted to using a single GPU as the render device, the render performance varied between roughly 11x and 16x faster than using its CPU.
Render performance improvement varies from fractal to fractal. Continue reading Render Performance on 2013 Mac Pro
Important Update: Apple’s OS X Mavericks 10.9.2 update (released the last week of February 2014) fixes this problem for the 2011 ATI GPUs found in many 2011 Macs. Also the new 2013 Mac Pro was apparently never affected by this problem and works correctly on both 10.9.1 and 10.9.2.
Customers on 2011 and 2012 Macs that have ATI GPUs should update their Macs to 10.9.2.

Update:
The render performance using the Mac Pro’s twin GPUs at the same time varied between roughly 20x and 28x faster than using its very good 6 core Intel Xeon CPU.
When restricted to using a single GPU as the render device, the render performance varied between roughly 11x and 16x faster than using its CPU.

Flam4CUDA for Mac and Fractal Architect have supported fractal rendering on the GPU since 2009. Flam4CUDA for Mac (I am its author) was an open source precursor to Fractal Architect.
Fractal Architect 3D, FA 2, and Serendipity all use the powerful OpenCL platform to render on either a CPU or a GPU. On OS X Mavericks, all recent Mac GPUs from Nvidia, ATI, and Intel are supported.
The beauty of rendering on the GPU is quite simple: Speed !! (speed varies by GPU model)

Mavericks 10.9.1 has a change that breaks the cached OpenCL rendering code for users using the Intel Iris Graphics GPUs. This change does not affect Nvidia or ATI discrete GPUs. Intel CPU based rendering is unaffected.
News Update (Jan 15, 2014): All 3 apps have been updated for this issue.
All 3 apps have had an update sent to Apple which fixes the problem. Apple’s Christmas shutdown for all App reviewers will delay the mandatory review by Apple. So you may not see the free update on the Mac App Store until the New Year or so.
Workarounds until the Update is Released
