Machoview 2.4 M1 Version

MachOView is a visual Mach-O file browser. It provides a complete solution for exploring and in-place editing Intel and ARM binaries.

旧版本代码编译之后打开文件可能会报下面的错误：

NSWindow drag regions should only be invalidated on the Main Thread!'

这个是由于进行状态更新的逻辑没有在主线程执行，通过下面的代码修复即可：

//----------------------------------------------------------------------------
- (void)handleThreadStateChanged:(NSNotification *)notification
{
  if ([notification object] == dataController)
  {
    NSString * threadState = [[notification userInfo] objectForKey:MVStatusUserInfoKey];
    if ([threadState isEqualToString:MVStatusTaskStarted] == YES)
    {
      if (OSAtomicIncrement32(&amp;threadCount) == 1)
      {
        [progressIndicator setUsesThreadedAnimation:YES];
        [progressIndicator startAnimation:nil];
//        [stopButton setHidden:NO];
          dispatch_async(dispatch_get_main_queue(), ^{
              [stopButton setHidden:NO];
          });
       }
    }
    else if ([threadState isEqualToString:MVStatusTaskTerminated] == YES)
    {
      if (OSAtomicDecrement32(&amp;threadCount) == 0)
      {
        [progressIndicator stopAnimation:nil]; 
        [statusText setStringValue:@""];
          dispatch_async(dispatch_get_main_queue(), ^{
              [stopButton setHidden:YES];
          });
//        [stopButton setHidden:YES];
      }
    }
  }
}
