I have heard you blame this on Apple for years now Chris, and I don't buy it. This is an increasing problem with Adobe PS CC and CC 2014 to the point that it's making our work flow impossible. You keep blaming Apple, and yet I can take a tif file I created in PS that won't display a preview image, open it in GIMP, or in Apple's preview thing and when I save I get an icon. When I do it in PS I get a white square. It's Adobe. It's not Apple.
I've been putting up with this since CS6, and now I'm on CC 2014, and it persists. It's total nonsense. It's ONLY Photoshop, and it's 100% reproducible 100% of the time.
