使用 010 Editor 模板 MachO.bt 去分析 Mach-O 文件格式，提示一个错误 Hit an unknown or unsupported load command : [-2147483608]，如下图：
对比出错的地方，仔细查看模板文件的代码，找到了是因为 LC_MAIN 这个 loadcommand 的错误信息，需要修改两个地方，第 331 行的
MAIN = 0x28 修改成 MAIN = 0x28 | REQ_DYLD，然后在 838 行 switch 语句的 default 上面添加以下代码。
|
1 2 3 4 |
case MAIN: uint64 entryoff; /* file (__TEXT) offset of main() */ uint64 stacksize;/* if not zero, initial stack size */ break; |
保存模板文件之后再运行，就发现解析正常了，效果如下图：
修改后的 MachO.bt 如下：
