I have installed Mac OS X mountain Lion on my laptop. Initial reviews was really good and did not wait too long to install it. It seems working fine however we still need to wait for the Facebook share function. The twitter works fine for me and it is amazing. I am gonna start using Safari probably after installing Mountain Lion.
In this morning I realise that some of the libraries are not active like gcc, make etc. Also some command line options are not working. SVN, MAKE commands were not functioning. Later find out that it was my mistake need to upgrade Xcode to 4.4 version to make everything work properly. So I have installed the new version of Xcode. But still the command line properties were not working properly.
Then I checked the command line tools in Xcode. Open Xcode latest version and Go to preferences -> Download tab. The command line tools was not installed we have to do it manually check it and install it. That resolved all the issues and The Mountain Lion functions well for me
