Loading kext, running chown on se_SecurityMessages did not fix mount_smbfs for me on Big Sur 11.6. Always unknown error.

... as was pointed out elsewhere, I had thought this member was static but it is not, it is an instance member.

I typed a whole reply, and this website threw it away. Yes I know about showSystemUserInterface(), it's not appropriate for our app at all (does not apply to kiosk-style / guest user scenarios). Short version: we can't conform the Apple Human Interface Guidelines and offer the functionality of portrait mode because Apple has chosen to not allow us to disable portrait mode when we need to get 60 FPS. It's very confusing for the user to start a task and have a totally unrelated step that includes an out-of-app popup. I filed FB11317925.

In my case project min level is iOS 12 so that's not it

Ah, i've been given a hand by a friend: this appears to be referenced in this webkit bug in the most recent comment: "So now we are back at forcing the users to tap and hold to save, hope this will get resolved soon!" https://bugs.webkit.org/show_bug.cgi?id=231995

... and this same friend has found this: https://github.com/WebKit/WebKit/pull/13111 So I guess it is fixed, and we just need an iOS update to include the fix.....

Update: i'm not sure why, but changing the required iOS version on the framework from iOS 9 to iOS 12 solved the problem. The framework did indeed run on iOS 9 but we don't need it to anymore...

Apple we also need this - we want to bring our iPad app, that prints a lot, to Mac. This stop us from being able to do it.

I have the same problem, did anyone solve this?

Hi Quinn attached is what I have (from firebase crashlytics). com.solodigitalis.booth_issue_3f6587b4a13013a99d1d4bdb8dba1fc2_crash_session_9a2ffedd2e2641cc929f9b66345a8c49_DNE_0_v2_stacktrace.txt Please note that for some reason the thread numbers are stripped out: in the one i've uploaded the main thread (#1) is the one you'll see has libc++ involved, and the thread that has crashed on DispatchQueue.main.sync is AppleCameraDataDelegate.dataQueue. Does this help? Would using a semaphore + dispatch async work better than the dispatch sync?

... @DTS Engineer it doesn't make sense to me why a semaphore+dispatch_async would be better but maybe we should try it? we can't reproduce this ourselves, it's our biggest crash in the wild though
