Hello Kirk
This is my first post, I've been using PM on Windows for a couple of years and found it virtualy faultless. Last week i moved my entire workflow to Mac, the speed of rendering thumbnails has taken a massive hit.
Big folders with 1200 cr2's virtualy freezes the system forcing me to restart, I have diabled the HQ thumbnails and set the default sort to 'file name' this helps a little. Even with this setup it will take over 10min to render the standard thumbnails. PM use to fly one a 3 year old Pentium 4 without hyper threading, this is a major head ache, making PM almost unuseable, if i preview an image it will undo the rendering of thumbnails. Copying brings up the same issue. The folders in qustion are on a 7200 rpm USB HD, same story with the internal HD. Very depressing with loads of big weddings in the next months!
