How to properly build for Mac (.app and Retina compatibility ?)

Hi everyone,

I’m packaging a project for Mac using Unreal Engine 5.5, and I’m facing two persistent issues:

  1. The game looks blurry on Retina displays
  • Despite setting r.ScreenPercentage=100 and adding NSHighResolutionCapable in the Additional Plist Data, the game still runs at a lower logical resolution (not matching Retina sharpness).
  • when I manually change the Info.plist, the game can’t be open (crash when open)
  • I also tried adding bUseDesktopResolutionForFullscreen=True and setting resolution in DefaultGameUserSettings.ini, but it doesn’t fix the issue.

Is there a definitive way to get true Retina rendering in a packaged UE5.5 Mac build?

  1. Extra folders appear next to the .app When packaging the game, I get a .app file plus extra folders like Resources/, FileOpenOrder/, and sometimes loose files. I was expecting a clean .app bundle with everything inside.

Is there a way to package the game so that everything is contained inside the .app only? Or is this normal behavior in UE5.5 on Mac?

Any help or insight would be much appreciated!

Thanks in advance!

For those wondering : I applied “SCALABILITY 1” or 2, or whatever in the console to have my build display good retina resolution
