It worked for me!! Packard Bell tk85. In 10.8.2 i have the same issue as other users: a strange noise from hard disk (or near it) and the shell screensaver didn´t shows. I've upgrade to 10.8.3 and the shell screensaver now works well, but the noise still sounds. BUT, if I put a MP3 playing at iTunes and quit the sound, the noise have disappear!! Sorry for my english, and hope this will help us to remove this annoying noise.
Hi everybody. I have follow this guide and it worked!! I'm on Packard Bell TK85 380SP. Only one thing, the vga connector. If I plug in with the laptop off and boot it after, the image shows on external screen but not on the internal display. If I plugin the VGA after ML boots up, the external display isn't recognized. Can I enable mirroring using the VGA??? Thanks!!!
