I've re-installed OSX 10.6.8 on a mid-2011 mini for the 3rd time in 18 months. I have not yet installed NFG's package, this time.
When I "Quick Look" (highlight in Finder & press the Space Bar) a file I get these results:
Print files (photos, pdfs, etc.) display fine.
Audio & video file either display an icon (usually the video files) and nothing else, or look like they are playing (icon shows & progress bar moves) but no audio.
If I open these audio or video files in a player (ie, iTunes or VLC player) they play as expected.
I've been chasing this problem ever since I installed Snow Leopard on this 2011 mini 18 months ago.
This time I've not installed any add-ons (menu bar enhancements, etc.) to see if it might be one of these causing the trouble. But the problem seems to be Snow Leopard and the 2011 mini.
On another partition on this mini I installed Mountain Lion (10.8). The Quick Look issue I've been having does not happen in 10.8.
Has anyone else experienced this issue with this combination?
Thanks,
