I have constant problem with sudden crahing of my MacBook Pro [15 inch, mid 2010] following the installation of OS 10.8 and updating to OS 10.8.2. The usual progrmas like Skype does not recognize the Built-in iSight for Video chats. The messages which used to work with Built-in iSight Video stipped working. The message says that video als do not work with this computer. Switching between MS Office 2011 in one window to another working with internet search engin stops every time.
I thought that the best solution for me is to go back to the OS 10.7, which worked flowlessly and never crashed in its life time. Is there abetter solution? If no, how can I uninstall OS 10.8.2 and reinstall OS 10.7. I have Time Machine Back up of my Mac.
