[Question] Boundaries for compatible macOS versions?

[mara004]

Hi @bblanchon,

I'd like to ask what the macOS compatibility boundaries are for the PDFium binaries? I would need this information to set the correct wheel tags for pypdfium2 on PyPI. As 'mac_deployment_target = "10.11.0"' is defined in 05-configure.sh, I am currently assuming macOS 10.11 as minimum supported version for both the arm and x64 binaries. I have also enabled compatibility with macOS 11.x using a second platform tag. Is this correct?

[mara004]

According to Wikipedia, macOS 11 is the first version to support ARM, so I restricted that tag to 11 only. And what about macOS 12? Are the PDFium binaries be compatible with that, too?

Hi @mara004,

I assume that your assumptions are correct, but I don't have definite answers to your questions. These questions should be addressed to the Chromium team; I'm just building a packaging the library.

Best regards, Benoit

Okay, thanks anyway.

Maybe @TcT2k would know better, he wrote the first macOS build.

I don't know any better, but would also think min 10.11 for x86 und 11 for arm should be correct. As far as I know the minimum hasn't changed in pdfium. But I haven't used it for a while. But pdfium isn't very SDK dependent (doesn't use any Cocoa stuff) so as long as it compiles with the specified macOS SDK it should also run.

@TcT2k Thanks. Do you know anything regarding compatibility with macOS 12? I have now tagged support for it on the off chance, but don't know whether it works.

[TcT2k]

I can't think of anything that wouldn't work with MacOS 12

[mara004]

Okay, nice. Maybe I'll hear from a macOS 12 user at some point.
