SUCCESS! Work fine with this fixes below like you can find in #15506
layout (binding = 0) buffer A {A_TYPE data_a[];} a[];
layout (binding = 0) buffer D {D_TYPE data_d[];} d[];
// Workaround for MoltenVK Bug, see #15498
// layout (binding = 0) readonly buffer A {A_TYPE data_a[];} a[];
// layout (binding = 0) writeonly buffer D {D_TYPE data_d[];} d[];
layout (binding = 0) buffer A {A_TYPE data_a[];} a[];
layout (binding = 0) buffer D {D_TYPE data_d[];} d[];
