He says the checksums are different but he doesn’t provide a diff to show how different. It could just be a single flipped bit or something. And that could happen in his own RAM/disk/CPU/router so seems premature to immediately blame Apple.

"I’ve not seen any file corruption when importing to Darktable, so I am convinced this is a problem with the Photos app."

Yes this argument is a bit unconvincing for me. Not saying Apple photos doesn't corrupt his files, but this is not real proper investigating either.

It seems to be an import pipeline bug.

Photos does a lot of extra work on import (merging RAW+JPEG pairs, generating previews, database indexing, optional deletion), so my guess is a concurrency bug where a buffer gets reused or a file handle is closed before the copy finishes.

Rare, nondeterministic corruption fits the profile.

He switched out his laptop.

Yeah, I would have been interested in the diff too.

That said, the article does mention replacing basically all the hardware and still encountering the issue. FWIW, my personal experience with Apple software so far is that the usage expected for Average Joe is well tested and polished. But stepping outside of that, it's "Here be dragons" territory very quickly.

Earlier quoted context omitted.

I always wonder about the motivation behind these polished, high-quality programs on the App Store which are not open source, and also don't collect (much) data, neither have ads in them.

It’s open source, else I wouldn’t recommended it https://github.com/LANDrop/LANDrop I used it along with another called Localsend, but the later one gave me a bit of headache and crashed while transferring some large files last time I used it, but still great as an alternative too, and it’s open source as well. Edit: Actually, you are correct, it seems they did close it! Try localsend instead.

Love LocalSend. Can be a bit finicky but for quick transfers between systems I love it. Use it so my work laptop, Linux gaming PC, and iPhone can easily pass staff around.

Here you go!

I ran both files through xxd then diffed them. I've literally changed every piece of hardware (at no small cost). "premature to immediately blame Apple" seems a bit off.
