I ran into the same issue on all three beta builds:
26A5388g
26A5378n
26A5378j
I added a guard as a workaround. My app has been live for about two weeks, and since releasing the new version, the crashes have stopped.
Hopefully Apple can fix this issue soon.
Guard code:
@implementation TBRemoteViewCrashGuard
+ (void)install {
if (![self shouldInstall]) {
return;
}
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
[self swizzleContainingWindowWillOrderOnScreen];
});
}
#pragma mark - Private
/// 仅在 macOS 27 上生效（Beta 系统存在此 Bug）
+ (BOOL)shouldInstall {
NSOperatingSystemVersion version = [[NSProcessInfo processInfo] operatingSystemVersion];
// macOS 27.x — 待 Apple 正式版确认修复后可收窄条件或移除
return version.majorVersion == 27;
}
+ (void)swizzleContainingWindowWillOrderOnScreen {
Class cls = NSClassFromString(@"NSRemoteView");
if (!cls) {
return;
}
SEL originalSel = NSSelectorFromString(@"containingWindowWillOrderOnScreen:");
Method originalMethod = class_getInstanceMethod(cls, originalSel);
if (!originalMethod) {
return;
}
// 用 block 包裹原实现，加 @try/@catch 防止断言崩溃
IMP originalIMP = method_getImplementation(originalMethod);
IMP guardedIMP = imp_implementationWithBlock(^(id self, NSWindow *window) {
@try {
((void(*)(id, SEL, NSWindow *))originalIMP)(self, originalSel, window);
} @catch (NSException *exception) {
// 仅吞掉 NSRemoteView 的断言异常，其它异常继续抛出
if ([exception.name isEqualToString:NSInternalInconsistencyException]
&& [exception.reason containsString:@"NSRemoteView"]) {
TBLogInfo(@"[RemoteViewCrashGuard] Suppressed NSRemoteView assertion: %@", exception.reason);
} else {
@throw;
}
}
});
method_setImplementation(originalMethod, guardedIMP);
TBLogInfo(@"[RemoteViewCrashGuard] Installed for macOS %ld.x", (long)[[NSProcessInfo processInfo] operatingSystemVersion].majorVersion);
}
@end
