Unreal Engine 4 launch failed on Mac OSX

I installed Unreal Engine 4.12.5 for my Mac OSX Mavericks but whenever I click “launch” in the Epic Games Launcher does nothing.What should I do?

Hi Sohum Basu

Mac OSX Mavericks is below the minimum software requirements to run UE4. Please review the following documentation on Hardware and Software needed to run UE4:

Hardware & Software Specifications

Thanks,

This doesn’t help to see the minimum requirements. When you launch the software it forces an automatic update and then it never works again. It’s clearly the Epic Launcher update because UE4 used to work fine on the same machine.
