Checking the specs it seems like 3456x2234 is the native resolution of you mac book:
https://support.apple.com/kb/SP858?locale=en_US#:~:text=3456%2Dby%2D2234%20native%20resolution
Which means you may actually be using dome DPI scaling to get a different resolution.
I don't know how that's configured on macOS exactly, but do you have DPI scaling enabled?

Those specs you quote are for the macbook pro (which is what the OP is using). The specs for my M2 air are here:
https://www.apple.com/uk/macbook-air-m2/specs/
and confirms 2560x1664 native resolution.
I don't have DPI scaling enabled as far as I am aware. The only option in settings seems to be some vague "Larger Text", "Default", or "More Space" which scales everything up or down. I tried all of them when I initially saw the problem and got the segfault that the OP initially reported on all of those settings.

So if I comment out the line here
https://github.com/SFML/SFML/blob/82b48a7520a2eb83576ec16d68ff9ea6d3d5d5bd/src/SFML/Window/OSX/cg_sf_conversion.mm#L94
then the modes which come back from
getFullscreenModes()
look more like what I'd expect for my Macbook Air M2:
Mode #0: 2560x1664 - 32 bpp
Mode #1: 2560x1600 - 32 bpp
Mode #2: 2048x1332 - 32 bpp
Mode #3: 2048x1280 - 32 bpp
Mode #4: 1920x1200 - 32 bpp
So the issue is possibly related to whether pixels or points are returned from
CGDisplayModeGetWidth()
etc ?
Edit: I've just been looking at this thread
https://stackoverflow.com/questions/42024942/cgdisplaymodegetwidth-height-sometimes-returns-pixels-sometimes-points
I wonder whether the comment "
The scaling factor for all modes is not the same. Some are 1:1, some are 2:1. A mode of size 1680x1050 points does not imply a pixel size of 3360x2100
" is relevant?

As this appears to be a bug, shall I summarise this in a github issue?
