Esxi running macos For selur

And if you had created a debug output it would have shown, something similar to

MP4Box output: dyld: Library not loaded: @executable_path/lib/libx265.179.dylib
Referenced from: /Users/selur/workspace/Hybrid/Hybrid.app/Contents/MacOS/lib/libavcodec.58.dylib
Reason: image not found

I deleted libx265.179.dylib since I thought it was a left over from an old x265 compile.
-> will look into it
