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.

There's a corrupted photo at the top of the article and the non corrupt version at the bottom, is that not enough?

Apple corrupted images on my iPhone where I can’t import them to my PC via photos, but I can backup the whole phone.

They finally recognized there is an issue, but there is no fix, as of a few weeks ago :(

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.

This is also my guess. It's really a bummer, and I'd report it to Apple but since it's nondeterministic I have no idea how to provide repro steps.

Earlier quoted context omitted.

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.

You figured out how to teleport people through local send?

No, it isn’t. The OP isn’t questioning whether the file changed, but asking what changed to the file, not what changed visibly.

The visible effect shown could be due to a change as small as a single bit flip. It also could be that large parts of the file got overwritten, or that it partially got zeroed. The exact kind of damage can help pinpoint the cause of the problem.

> Turns out “delete after import” was a huge mistake.

That's a mistake no mater what application you're importing to, else we'll be graced with another blog post, "Darktable app Corrupts Photos".

What's the purpose of RAW+jpg though? Seems rather redundant?
