After installing DP1 of Yosemite on my Retina MacBook Pro, it seemed to be running pretty smoothly. Here's one feature that is imperative to my weekly workflow that it doesn't seem to properly support. I'm trying to delete pages from this PDF in preview: http://s3.amazonaws.com/NewarkNazMediaDrive/The%20Firehouse/Documents/Binders/FH%20ChartsMaster.pdf Typically, I just enable thumbnail view, select the pages I want deleted, hit DELETE on the keyboard, and I'm ready to add the new pages for the week. Does anybody have any ideas? I can boot to my Mavericks drive if I need to, but if I can do it in Yosemite, I'd rather.
