I’m currently using 12.11.0.26 which works fine when packaging in other versions of UE but gives me the sdk error in 5.1, really strange that 5.1 would require an older sdk than previous versions of UE4
Ok worked out I don’t have the right version of xcode installed for 5.1, I need 13.4.1 as the minimum but my old af mac won’t support it so guess i need to buy a new mac that supports the Monterey OS so I can install the right version of xcode
