新的版本的MacOS，官方已不建議用 crontab

cd ~/Library/LaunchAgents
vim net.alexchang.<YOUR_JOB>.plist

貼上以下的code再修改，下面的範例是每天(86400秒)執行一次，其他觸發條件建議看文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "[<http://www.apple.com/DTDs/PropertyList-1.0.dtd>](<http://www.apple.com/DTDs/PropertyList-1.0.dtd>)">
<plist version="1.0">
	<dict>
	<key>Label</key>
	<string>net.alexchang.<YOUR_JOB></string>
	<key>ProgramArguments</key>

	</array>
	<key>StartInterval</key>
