ScreenCaptureAccess.preflight returns incorrect value for Intel based 64bit Mac

[Pranav2612000]

The function ScreenCaptureAccess.preflight [ Ref ] returns incorrectly for Intel based 64 bit Macs.

On further inspection, the reason for this is that the external method CGPreflightScreenCaptureAccess returns a value which is not 1 ( even if the permissions have been given ).
From my research, I've found that it returns a number whose lowest 8 bits are 0. So something like the following should work

That's what I'm doing in my fork here

This is working good enough for me. What do you think about this approach? Does it make sense? I'm open to submitting a PR, or if you have a better solution in mind, I'll love to implement it.

The correct way to work with external booleans is always to compare them against NO / 0. So rather, you should use != 0

[Pranav2612000]

Yup @madsmtm . That was what I tried first, but I observed that CGPreflightScreenCaptureAccess returns a non zero value ( the last 8 bits of which are 0 ) if screen capture permissions are not present. So the function would always return true, which is not the correct behaviour.

Is it possible that it's something to do with Boolean being 1 byte by int32 being 4 bytes? Because the last 8 bits of the returned value are always 0000 0000 or 0000 0001

Oh... Actually, you're right, the issue is that the definition in Rust is using boolean_t instead of bool :/

[Pranav2612000]

Yup. Thank you @madsmtm
What do you think the next steps should be here? Happy to submit a PR

[madsmtm]

Can't answer that, not a maintainer here, sorry
