Apple Photos app corrupts images

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.

What's the point of it? It is well known in the industry they ignore bugreports.

Also, this bug doesn't affect the majority of users, so it won't ever be fixed.

I worked on the Photos team a decade ago — some of what you're saying I can vouch for. If it is a rare occurrence, that lowers the priority of the bug. Data corruption though? That moves it to the top.

I'll tell you a secret though that kind of pisses me off. If you have shipped with a bug, that automatically lowers the perceived priority as well. You know, as opposed to introducing a new bug in a new release. "We've already lived with that old bug…" seems to be the mind set. Oh well.

To be sure though, if you saw the number of bugs that queue up for a popular app like Photos, you'd know that fixing all of them is not going to be possible — some kind of system of prioritization is required.
