Using new materials freezes editor (OS X)
Every time I use a material I have never used before in a project, Unreal Editor will freeze for about 1 - 2 minutes. During this time, the editor is completely unresponsive and I have a spinning beachball cursor (I'm on a Mac). After a long time, it will finally unfreeze, and proceed to compile shaders.
This also applies to opening levels. If I open a level (like an included example level) that uses materials I've never used before in the project, the editor will freeze for about 2 minutes -- per material! I just finished loading a level (Starter Map in the StarterContent folder) that took 20 minutes to load!
Everything else seems very fast and responsive. It only freezes if I have never used the material anywhere in the project -- it will work fine even if I have used it in another level. Loading levels that I created, or that do not use new materials, is very fast. I'm also new to Unreal Engine, so I might be doing something wrong, but I've made sure to follow the instructions given in the tutorials.
I'm using Unreal Engine 4.7.2.

Would you mind providing me with your full system specifications?
Processor, Integrated Graphics, OS etc...
There are options within the Editor that can help improve your overall performance. In the Main viewport there is a dropdown that says 'Settings' which will contain the location of the 'Engine Scalability' settings.
Editing both of these settings will hopefully improve your performance. Let me know if this helped or if you need further assistance. This issue seems to be hardware related.
