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"

Editor Crashes On Launch On OSX 10.13

Every time I try to launch 4.14.3 (it's the latest I can use since my graphics card doesn't support the Metal) the splash screen doesn't even have time to show up before I get this crash:

This happens on every version of UE4 except on 4.0-4.5. From 4.6 onward this crash happens.

One thing I would like to note is that this never happened before I upgraded to Mac OS X High Sierra. I have completely deleted everything that has to do with UE4 on my Mac and done a clean install of the launcher and the editor but to no avail.

I realize this is an older version, but it's the latest version I can use. Plus, all of my projects are on 4.14.

Here are my system specs: Mac OSX High Sierra 10.13 (17A405) MacBook Pro (15-inch, Late 2011) 2.5 GHz Intel Core i7 AMD Radeon HD 6770M 1 GB/Intel HD Graphics 3000 512 MB

Product Version: UE 4.14

Exactly the same thing happens to me, please what do we have to do? Also I'm unable to use more recent versions since my video card does not support metal.

System specs: Mac OSX High Sierra 10.13, Mac Pro (Mid 2012), 2 x 2,4 GHz 6-Core Intel Xeon, 2 x ATI Radeon HD 5770 1 GB

did you find a solution

I even tried to download Unreal source code and recompile it myself: it goes beyond my skills, I had no luck. Too bad cause I largely prefer Unreal over other Game Engines, but looks like Epic decided for us what hardware to use. Wierd because my MBP early 2011 (upgraded with an SSD) is still a decent dev machine.
