Q: Mountain Lion doesn't display Finder preview icons for .ARW files? (RAW pictures taken with SONY cameras)
This is something that I find rather ridiculous, and have a hard time believing no-one at Apple has addressed yet.
Basically the problem is that neither Mountain Lion nor Lion show Finder thumbnail preview images for pictures that are taken with SONY digital cameras.

This is something that Snow Leopard, as well as multiple earlier iterations of OS X used to do without any problem. The professional photographer community who uses SONY professional DSLR cameras is up in arms about this. And we've all been crossing our fingers that perhaps the Mac OS X 10.7.1, 10.7.2, 10.7.3, 10.7.4, or possibly the 10.8 update would fix this issue for us.
Several of us have filed bug reports over the past year or two. See this thread: https://discussions.apple.com/thread/3213982?tstart=0
This is a flaw in Apple's operating system. Especially considering that there are supposedly 200+ "new features" which were just released in Mountain Lion.
Those of us who work with SONY cameras every day would probably have paid the $19.99 upgrade price for just one "feature". And not even a new one. An old one. The ability to see our pictures in the Finder. Pretty basic stuff.
Hopefully someone fixes this for us with the release of Mac OS X 10.8.1
Please. And thank you.
Mac Pro, OS X Mountain Lion
