So the issues you are seeing is because you are using the scfb driver 
which is a software only driver.  So it would be expected to see really 
poor performance of 3d applications, as well as others which require 
hardware acceleration failing to start.

i am not sure about the status of DRM on apple hardware but there might 
be someone on this or the freebsd-x11@ list who can let you know if 
hardware acceleration is supported.
