本文介绍了一种在macOS上运行Python多进程程序时遇到的错误，并提供了详细的解决方案。通过设置环境变量OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES来避免程序崩溃。

python multiprocessing程序运行时，报错：

objc[2483]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called.
objc[2483]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
