Mac D2GFX_UpdateScaleFactor: void __cdecl (void)
The Mac body has no argument reads (no [EBP+n], no ECX/EDX use before they are written). It copies the pending scale global into the current-scale global and calls renderer slot +0x60 with it, then a plain RET. The caller ViewDraw2 0x0007cae5 calls it bare and then calls D2GFX_GetScaleFactor. Matches the Windows twin 0x004f65c0 (void (void)).
