It would be better to have a custom dialog - but from a signal handler? Yep. A dialog would be preferable.
Mr Ash suggests kqueue and GCD based handlers which can (though I have not tested this) run arbitrary code post signal. https://mikeash.com/pyblog/friday-qa-2011-04-01-signal-handling.html However PLCrashReporter uses a straight ahead signal handler: https://github.com/plausiblelabs/plcrashreporter/blob/e6d1ac18d758e8e0197f32f927bb6b31b8559f95/Source/PLCrashReporter.m The PLCrashReporter repo does contain GTMSignalHandler (part of the google toolbox) which is kqueue based but this is not utilised. Perhaps you could utilise the kqueue based handlers, show your UI and then call the PLCrashReporter signal handler (which in turn calls your signal handler with containing exit(-1). > > > Throwing up any sort of UI in the callback will be unreliable due to the > normal re-entrant code caveats - I think the Adium code does this anyway. > > Where did you find that? https://www.plcrashreporter.org/documentation/api/v1.2/async_safety.html http://landonf.bikemonkey.org/code/objc/Reliable_Crash_Reporting.20110912.html > > Well, I guess a crash is a crash.
