Bug ID: 51557
           Summary: GetSystemFirmwareTable fails to return SMBIOS on Apple
                    Silicon Macs
           Product: Wine
           Version: 6.14
          Hardware: aarch64
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs@winehq.org
          Reporter: bshanks@codeweavers.com
The macOS implementation of GetSystemFirmwareTable() retrieves the system's
actual SMBIOS table using IOKit. This fails on Apple Silicon/ARM64 Macs, since
they don't have an SMBIOS table.
This breaks any applications that depend on getting an SMBIOS table (like the
Rockstar Games Launcher) or that look for the
HKLM/Hardware/Description/System/BIOS registry keys.
I think the fix will be to use the SMBIOS table creation functions used by
Linux currently, with strings and data (serial number, UUID, etc) coming from
IOKit if possible.
