我已经尝试过对monoDevelop.app内容文件夹的许可，并且也适用于所有子文件夹。
答案 0 :(得分：18)
我也遇到了这个问题。尝试删除MonoDevelop数据（这种方式对我有用）。
打开终端并运行：
rm -rf ~/Library/Preferences/MonoDevelop-Unity-5.0
答案 1 :(得分：8)
更新（2018年2月）：
自2018年起，Unity Technologies一直推荐 Visual Studio for Mac 作为Mac用户的首选编辑器。在所有这些红旗和警报告诉你逃离门之前，请注意VS / Mac是Xamarin Studio（由微软收购）的分支，而后者又是MonoDevelop的分支。
由于它是一个分支，VS / Mac只是MonoDevelop的更新，更积极地维护，并且更少崩溃，内存泄漏和其他生产力下降。在我过去一个月的使用中，VS / Mac一直非常稳定，它的内存占用也非常稳定，据我所知，没有明显的膨胀。
最后，VS / Mac有三个版本：社区，专业版和企业版。
您可以从http://visualstudio.com下载VS / Mac 下载和安装就像安装MonoDevelop或Xamarin一样简单。
只需进入Unity首选项，选择VS / Mac作为外部代码编辑器，就可以了。
试一试。
Unity已发布补丁以解决MonoDevelop崩溃问题。以下版本的Unity存在补丁：
如果您使用的是未列出的版本，则可能需要更改Unity版本，回滚Mac OS X或使用Xamarin解决方法。
以下是Unity补丁的URL：
https://unity3d.com/unity/qa/patch-releases
以下是Unity论坛链接以获取更多信息：
https://forum.unity.com/threads/unity-and-macos-10-13-high-sierra.474527/
答案 2 :(得分：2)
我已经为此付出了丰厚的回报，完全了解有一些解决方法。我只是喜欢使用默认的集成MonoDevelop，我希望这可以解决。 Unity is already aware of the issue with MonoDevelop + High Sierra, but no solutions have been offered.
对于那些寻找解决方法的人，可以下载MonoDevelop + Xamarin Studio straight from here，这对我来说没有崩溃。
答案 3 :(得分：0)
如果您仍在寻找答案，那么这里是有关Unity不再支持该问题的解决方案的信息：http://www.hireunitydeveloper.com/unity-monodevelop-not-opening/
答案 4 :(得分：0)
如果您使用多个监视器，则造成MonoDevelop崩溃的一个原因是在上一个会话期间在辅助监视器中打开了IDE。 在这种情况下，您不需要删除所有首选项，而是编辑MonoDevelopProperties.xml并删除WorkbenchMemento节点内的“ bounds”属性：
<Property key="bounds" value="-37, 162, 1920, 1020" />
答案 5 :(得分：0)
如果您使用两个或多个监视器，请尝试将Unity IDE移至另一个监视器，然后启动MonoDevelop。 由于某些原因，如果您在另一台显示器上关闭了MonoDevelop主窗口，然后尝试在另一台显示器上再次启动它，则会崩溃。
