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"

Unreal Version 4.21.2 Won't Launch on my macbook


I am on MacOS Version 10.12.6 and when I got to launch Unreal Engine it will just close my Epic Games launcher and do nothing. When I go to use Unreal frontend to launch I get this error on the picture attached to the question. I figured a reinstall would fix this problem but it did not. I am the Audio guy for my team and I would really not like to Update this mac as it has stable versions of other Plugins for DAWs.

If there are anyways known for repairing library files for MacOS please let me know! Thanks!

I think a download of the MacOS library files should fix this issue

In the first screenshot it says that you are missing the MacOSX SDK. Try to intsall that first.
