Cannot package on Mac – UE requires older Xcode but macOS refuses to launch it

Hi everyone,

I’m trying to package my project for macOS, but I’ve run into a version compatibility issue.

My setup:

  • Unreal Engine: UE5

  • macOS: Tahoe

  • Xcode installed: 26.2

When I try to package the project, UE throws errors saying that the compatible SDK is 15–16.4.

So I downloaded Xcode 16.2, but macOS refuses to open it and shows this message:

“In order to use Xcode you need to update to the latest version. The version of Xcode installed on this Mac is not compatible with macOS Tahoe.”

So I’m stuck between:

  • New Xcode that UE doesn’t support

  • Older Xcode that macOS won’t run

Has anyone encountered this situation?

Is there any workaround besides downgrading macOS or using another machine?

Thanks!
