IOAVServiceCopyEDID() is a private API of macOS; ideally, maybe we should avoid using it. But this is the most straightforward way to get the EDID of an external monitor on Apple Silicon. --- dlls/winemac.drv/cocoa_display.m | 88 +++++++++++++++++++++++++++++++- dlls/winemac.drv/display.c | 4 +- dlls/winemac.drv/macdrv_cocoa.h | 4 +- 3 files changed, 92 insertions(+), 4 deletions(-)

Neither IOAVServiceCopyEDID() nor "IODisplayEDID" is available for Apple Silicon MacBook's built-in screen, let's try to generate EDID data based on display parameters from Core Graphics APIs. This isn't perfect since some parameters are missing, but at least it satisfies some Unreal games. --- dlls/winemac.drv/cocoa_display.m | 195 +++++++++++++++++++++++++++++++ 1 file changed, 195 insertions(+)

You should be able to call `IOObjectRelease(service)` right after `IOAVServiceCreateWithService` (regardless of whether IOAVServiceCreateWithService succeeds or not), then you avoid having to call `IOObjectRelease(service)` later in the function.
Same with `avservice` also.

Maybe also a good idea to call `CFDataGetLength()` here and ensure the CFData is large enough that the `edid_ptr` accesses below won't be reading past the buffer size.

Could `edid` just point to the calloc-ed buffer, and have `*prop = edid` at the end, that way you avoid the memset and memcpy?
Overall looks good, I tested the 3 code paths.
