Re: new proc failed with errno: 0x56 Message when trying to Download Sims 4
Your issue is that you have Catalina installed on an unsupported Mac. Your Mac only supports up to 10.13.6 High Sierra and is not Metal compatible.
You will not be able to currently run the game on your Mac for two reasons:
- The current version of the game requires a Metal compatible Mac which yours isn't. Please read this FAQ on the Legacy Edition for Mac. It will not run on your Mac.
- The Legacy Edition for the game still has a 32-bit executable file which runs when you launch the game. Catalina does not support 32-bit so it will not launch on your Mac.
To play the game you must wipe and reinstall a compatible version of macOS on your Mac. It may be necessary to reverse whatever hack has been applied to your Mac to enable this.
