(Mac) Unreal Engine 4 freezing when applying materials/textures
My system info:
2010 Macbook Pro 2.66 GHz Intel Core i7 8 GB RAM NVIDIA GeForce GT 330M with 512 MB VRAM Running OS 10.10.2 (Yosemite)
After a bumpy start (a few crashes when trying to install Unreal Engine 4) I recently installed Unreal Engine. Though I wouldn't describe performance as spritely, it has so far functioned well enough for the very limited tasks I've attempted. I have been able to do everything required in the first 9 video tutorials of the initial "Basics" series. But in lesson 10, a new material is applied to the floor. Whenever I try to do this, the engine totally freezes up and all I can do is force quit. This has happened five times in a row now, so I suspect it's hopeless.
I understand well that my computer is beneath the recommended [minimum] system specs, but I keep reading anecdotes of others using Unreal Engine 4 on similar or even less powerful Macs to varying degrees of success. Is my problem rooted in Unreal Engine, or am I simply asking too much of my computer?

This almost certainly isn't a crash - we have a crash-reporter GUI that pops when it crashes - the Editor is just busy & not being very informative.
Let us check the project logs to see what it was doing when you forced it to quit by uploading the logs from: /Users/[your-username]/Library/Logs/UnrealEngine/[your-project]
You can hold the Alt/Option key while clicking on Finder's 'Go' main menu item to reveal a quick link to the Library folder if you can't find it.
I suspect it may just be compiling shaders & textures which can leave the Editor unresponsive for some time. You'll see ShaderCompileWorker instances in Activity Monitor.app if it is shader related & if it is texture compression then UE4 will consume all the CPU & memory it can get its hands on. Both processes just take some time.
There will be an update in 4.7.4 which should dramatically improve texture compression performance on OS X, which should hopefully make a huge difference to you in these situations.
