Just tried creating a material in 4.19 and everything I do causes a bunch of errors …
Edit: This is really annoying, everything else works fine & compared to older versions runs quicker. Any ideas ?
Do you use launcher or github version of the ue4? I’m asking, because I had similar issues in one of the earlier github engine versions (master branch of 4.12 or 4.13, I don’t remember). Maybe, there was some issues with compilation
UE4 not Github.
do you mean launcher? github hosts the source code of UE4
The error shows something about Metal Lib, I’m guessing the Metal gaming Framework. Coding with Xcode a similar problem just requires the latest update. Thing is my iMac is late 2012, I may not have the latest libraries really not sure, there are no current updates to download. Also my graphics card is really old so may not support it anyway.
Having the same issue
Installed 4.19.2 from launcher

MBP late 2013 on high sierra
