Hi all,


after the Montain Lion upgrade (10.8.2) on MacBook Pro retina I'm not able to use USB key and externals HD.

They are not present on the desktop and on the finder sidebar.

Also the input devices (mouse and keyboard) responds late if I don't use them for some time (10/15 sec)...


I don't want to make a clean installation...

Any suggestions?


Thank you very much!
