View Full Version : SL to ML, now nasty screen flicker

Aug 3, 2013, 10:18 AM
I have a 2.4Ghz Mac Mini that had been running beautifully under Snow Leopard.

The latest upgrade for a piece of software I use requires at least Lion, so I used it as the excuse to upgrade my OS.

It was a real shock how sluggish ML is from SL. But on top of that, I now have an extremely annoying flicker on my screen (an Acer 19-inch, I believe).

I looked online and I see lots of screen flicker messages, but few answers. Nvidia has a driver specifically for ML, but that didn't seem to help. I've upgraded the RAM to 8 gigs (the max). The sluggishness is nearly gone but the flicker remains.

Any other thoughts?
