经过大量的研究，我发现这个问题没有完美的解决方案。我尝试重写NSApplication并将其设置为NSPrincipalClass，甚至实现了Sentry -没有成功。但是我找到了一种使用方法swizzling和FIRExceptionModel绕过AppKit的方法。

注意:首先，为了让Firebase Crashlytics在MacOS上工作，你需要在你的AppDelegate的didFinishLaunchingWithOptions中包含以下内容：

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults registerDefaults:@{@"NSApplicationCrashOnExceptions" : @"YES"}];

然后，您需要创建一个NSApplication类别并混合使用_crashOnException方法：

#import <objc/runtime.h>
#import "NSApplication+CrashReport.h"
#import <FIRCrashlytics.h>
@implementation NSApplication (CrashReport)
+(void)load {
    static dispatch_once_t once_token;
    dispatch_once(&once_token,  ^{
        SEL crashOnExceptionSelector = @selector(_crashOnException:); // Ignore 'Undeclared selector' warning.
        SEL crashOnExceptionReporterSelector = @selector(reported__crashOnException:);
        Method originalMethod = class_getInstanceMethod(self, crashOnExceptionSelector);
        Method extendedMethod = class_getInstanceMethod(self, crashOnExceptionReporterSelector);
        method_exchangeImplementations(originalMethod, extendedMethod);
- (void)reported__crashOnException:(NSException*)exception {
    NSArray<NSString*> *stacktrace = [exception callStackSymbols];
    [[FIRCrashlytics crashlytics]setCustomValue:stacktrace forKey:@"mac_os_stacktrace"];
    FIRExceptionModel *errorModel = [FIRExceptionModel exceptionModelWithName:exception.name reason:exception.reason];
    // The below stacktrace is hardcoded as an example, in an actual solution you should parse the stacktrace array entries.
    errorModel.stackTrace = @[
        [FIRStackFrame stackFrameWithSymbol:@"This stacktrace is fabricated as a proof of concept" file:@"Hello from Serge" line:2021],
        [FIRStackFrame stackFrameWithSymbol:@"__exceptionPreprocess" file:@"CoreFoundation" line:250],
        [FIRStackFrame stackFrameWithSymbol:@"objc_exception_throw" file:@"libobjc.A.dylib" line:48],
        [FIRStackFrame stackFrameWithSymbol:@"-[__NSCFCalendar rangeOfUnit:startDate:interval:forDate:]" file:@"CoreFoundation" line:453]
