Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

EU4 editor crashes on startup (mac)


Im trying to run the EU4 Editor and it crashes as soon as I open a project. It doesn't matter what project whether it is a demo on the marketplace, a blank project or one of the templates. I am able to get up to the first tutorial window on startup before it freezes up and crashes.

I have installed Xcode, updated the engine to 4.1.1 and installed a fix found on the forum (https://answers.unrealengine.com/questions/13712/crash-hidinputinterface-macosx-109.html#answer-13800), however It still continues to crash.

Here are my Mac's specifications:
Processor Name: Intel Core i5
Processor Speed: 2.66 GHz
Memory: 12 GB
Video Card: ATI Radeon HD 4850 512 MB
OS Version: OS X 10.9.2

The only thing I can think of is maybe the fact my graphics card is 512MB not 1GB this could cause the editor to simply not run? Could this be the issue?

So, I installed UE4 on the windows (boot camp) side of the mac and it runs. Therefore my graphics card being 512MB shouldn't be the issue right? Does anyone know of some known reason why UE4 wont run on the mac?

Technically the ATi 4850 GPU is beneath the minimum requirements for UE4, as it is only an OpenGL 3.3 GPU. On Windows it will work, but the Mac OS X OpenGL drivers for the 4850 don't support some rendering features that are necessary for UE4 to run. The 4.2 release should add minimal support for these cards on OS X at the expense of some rendering effects we can't support.
