OSX 10.11(El Capitan)beta 2 / beta 3上的Xcode 6.4

我试图在El Capitan上运行 Xcode 6.4,我可以使用 this发布的说明进行运行.

但是,我正在寻找一种运行它的方法,无需任何外部程序,因为我以前用OSX 10.10(优胜美地)运行.

我发现this帖子指向this说明,但它不工作.这些是说明

1. Open this file /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/Exception.plist
2. Find lines with name xcode in them (07003)
3. Edit value HardDisabled from YES to NO

4. Save and reboot

   1.a) If you can’t save because file says it’s locked then enable
   rootless mode (sudo nvram boot-args=”kext-dev-mode=1 rootless 0″ or
   sudo nvram boot-args=”kext-dev-mode=1 rootless=0″) and reboot.

   1.b) If you still have problem,copy Exceptions.plist to Desktop (or
   wherever else) and edit it them.

   1.c) Save it and them remove
   Exceptions.plist in System (sudo rm -rf
   /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/Exceptions.plist)

   1.d) Copy file from Desktop (or wherever else) to
   /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources and
   reboot.

我无法使用上面的说明编辑Exceptions.plist文件,但经过很多尝试,我找到了编辑它的方式.
Here你可以找到编辑它的说明.

毕竟,我仍然收到消息

You can’t open the application “XCode.app” because it is not supported
on this type of Mac

解决方案1
我唯一没有做的是在更改后重新安装XCode 6.4.我重新安装它,它的工作原理！

Dave Wood提供了另一种解决方案,以避免重新安装XCode. This是帖子,他在他的答案中发布的脚本是here
