Hi,

 

Today I went from 10.6.8 to 10.8.2 (Mac Pro 2009, Apple LED 24), and everything was fine except for one thing: The display is now constantly flickering!

 

(I've been using a Mini Display extention cord since I got my Mac Pro without any problems.)

 

When I connect the display directly to the Mac, everything is fine. But as soon as I insert the extention between the Mac and the display, the flickering begins.

 

As the extention worked right up to the second I installed 10.8.2, it must be a software issue.

 

Has anyone else experienced this?..

 

Thanks.
