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 at winehq.org
Reporter: bshanks at 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.
