On Mac, if you have an app open and you try to launch it again, the Mac just switches to the open app. You can force it to open a new instance by passing the option "-n" to the launcher. In a terminal, run

open -n /Applications/MonoDevelop.app

还请注意，MonoDevelop可以打开多个解决方案.为此，只需取消选中打开"对话框中的关闭当前解决方案"复选框，或者在欢迎页面"中单击最近打开的项目之一时按住控制键即可.

Note also that MonoDevelop is capable of opening multiple solutions. To do this, simply uncheck the "close current solution" checkbox in the "Open" dialog, or hold down the control key when clicking on one of the recently opened projects in the Welcome Page.
