On macOS，Install the input method has always been a nightmare，To open the system input method directory，We should drag input into this directory，The process also enter a password，Full manual bad enough，After we had to reboot the system to recognize，Not really a headache。
Later, we gradually realized the problem，Pocketed input method is also provided macOS standard installation package pkg。
