UE4.5 demos broken on OSX Yosemite
I updated my iMac from OSX 10.9.5 to 10.10 (final) and most of the the UE4.5 demos are broken and unusable. They worked flawlessly on OSX 10.9.5.
Take a look at Matinee on OSX 10.10:
The characters are all messed up and some shaders are not correctly represented.
Here is the ContentExamples Animation sample scene:
Seems like animated characters are the most affected.
Is this a known problem?
This should be fixed by the full 4.5.1 update which includes the required workaround for an Apple/Nvidia OpenGL driver bug introduced in 10.10.0.

There's a bug in NVIDIA driver in Yosemite that causes this. Apple and NVIDIA are working on this, but in a meantime we prepared a workaround, which you can download from here: https://s3.amazonaws.com/unrealengine/qfe/QFE-FromCL-2326468-Shelve-2331902_Mac.zip (92 MB) Just unpack the zip file and run the patch installer. It will also be included in UE 4.5.1.
