Solving the GLFW First Responder Problem on Mac OS X

If you are running OpenGL in the XCode and getting this error message on program start-up.When you run your OpenGL program you find that you will need to resize or move the window before rendering will begin. If this is the case you are in the right place, this articles will show you how to solve it.
Error Message:
Setting <GLFWContentView: 0x10283a620> as the first responder for window <GLFWWindow: 0x1007396e0>, but it is in a different window ((null))! This would eventually crash when the view is freed. The first responder will be set to nil.
GLFW v3.2.1 causes this problem. You have probably installed glfw from brew and it has installed this version because it uses the current stable release. In my previous article, I actually show you have to install glfw using brew. But it turns out that this is not as stable as it makes out on a Mac.
So to solve the problem you need to install the master branch of GLFW, which involved downloading the source and building from scratch, which is a good thing for your system. Here are the steps to do this:
Uninstall glfw 3.2.1
($brew uninstall glfw)
Download glfw-master from https://github.com/glfw/glfw and unzip
In the root of the folder structure:
Run:
$ cmake
$ make
Output:
$ make

This should have built the library and installed it in the directories above.
Then in your Xcode library
Add Libraries:
libglfw3.a (from /usr/local/lib folder)
You also need:
CoreVideo.framework
IOKit.framework
Cocoa.framework
OpenGL.framework
Then the project should build
