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
It is easy to workaround this issue. Using the Mac Finder, we will trash the cached OpenCL programs. Here are the steps for each app:
Fractal Architect 3D
- Open the Mac Finder.
- Using the Finder menu, click on this menu item: Go > Go to Folder …
- Enter: ~/Library/Containers/com.centcom.Fractal-Architect3D/Data/Library/Caches
- Move the folder com.centcom.Fractal-Architect3D to the Trash.
- Restart the application.
Fractal Architect 2
- Open the Mac Finder.
- Using the Finder menu, click on this menu item: Go > Go to Folder …
- Enter: ~/Library/Containers
- Move the folder com.centcom.Fractal-Architect2 to the Trash.
- Restart the application.
Serendipity
- Open the Mac Finder.
- Using the Finder menu, click on this menu item: Go > Go to Folder …
- Enter: ~/Library/Containers
- Move the folder com.centcom.Serendipity to the Trash.
- Restart the application.

I tried to move the folder: com.centcom.Fractal-Architect3D to the Trash but Fractal Architect 3D keeps crashing at opening the program. I was able to use this programm only twice and I paid 50 euro for it. I will ask apple for a refund of my money because, nothing, really nothing helps to get this program running. I am using Yosemite 10.10.2 for software.

With Fractal Architect 4, there is a free builtin GPU rendering trial, so you can see whether GPU rendering is compatible with your Mac before purchasing the GPU rendering option.
When FA 3D was released, we had no idea that Apple would not fix their OpenCL drivers.
