Running UE4 on a Mac?

I am getting a new laptop soon specifically for development with UE4 and I was curious about how well the engine performs on Mac? Is there any noticeable differences in performance, features, or support between the Windows and Mac version of the engine?

The specs for the Mac laptop are equivalent to the following:

Intel Core i7 4800MQ (2.70GHz)
NVIDIA GeForce GTX 880M 8GB
128GB SSD
1TB HDD
16GB Memory

They have found that performance on Mac is not as good as Windows, on the same hardware. But that’s something they’re working to improve. That hardware should be fine
