The preprocessor directives should be more reliable especially on older machines.
See other parts of the code which are handled that way and adopt for your case.

Here and in other chunks you can join the if() conditions into one and avoid the duplication of the old code.

This should use a SDK guard, like:
#if ((TARGET_OS_IPHONE && __IPHONE_OS_VERSION_MAX_ALLOWED >= 100000) ||
(TARGET_OS_OSX && __MAC_OS_X_VERSION_MAX_ALLOWED >= 101500))
(You can check https://epir.at/2019/10/30/api-availability-and-target-conditionals/ where
I provided a more details about these)

This should be extended for other OSes too, the API is not just deprecated on iOS.

The preprocessor guard is meant to void the @available condition.
Also something appears not yet to achieve what you want, as on MacOS 13.4 I still get the deprication warning:
libavdevice/avfoundation.m:776:29: warning: 'devicesWithMediaType:' is deprecated: first deprecated in macOS 10.15 - Use AVCaptureDeviceDiscoverySession instead. [-Wdeprecated-declarations]
return [AVCaptureDevice devicesWithMediaType:mediaType];

why not #else... #endif ?
