Mac OS X "Has Mountain Lion been feeling faster for you compared to Lion on the same machine? It's probably not just you: Mountain Lion appears to include improved graphics drivers and low-level graphics subsystem improvements. According to our testing, these improvements result in an approximate performance increase of up to 10 percent. Those improvements can make your current hardware feel faster despite the fact that your CPU can't magically crunch numbers any faster. The changes also lay the foundation for Apple to update OS X's OpenGL support in a more timely manner, which could potentially lead to better graphics performance in the future."

6) "make" doesn't work anymore. She is using XCode for a major codebase (OpenCV) and even reinstalling hasn't solved this

In order to slim down OS X and Xcode itself there have been a few changes that caused this problem of yours. Command line tools are no longer bundled by default, but available as an optional download you can trigger from Xcode itself (and they did a good thing let me tell you... no longer having to download 3GB or so of extra stuff at each iOS SDK point release).


1.) Install Xcode 4.4 from the App Store (free).

2.) Open Xcode, and in XCode's Preferences > Downloads you can install command line tools.

3.) Make it system-wide clear where these tools are: sudo xcode-select -switch /Applications/

4.) Accept the command line build utils license: sudo xcodebuild -license

(scroll down and the you have to type accept or agree or something ;) )
