If you, like me, ran into issues after installing Mountain Lion, here is the list of fixes.

Dropbox

Dropbox “copy public link” option disappeared from the menu. This is easily fixed by getting the patched version of dropbox

Virtual Box

You’ll need to download version 4.1.18 and re-installed it.

Git

Git gives “command not found” message. Steps to fix:

1. open your ~/.bash_profile
2. add this line to the file:

export PATH=$PATH:/usr/local/git/bin/

3. Save & close the file and type on the terminal:
$ source ~/.bash_profile
