I use Photoshop CC2015 on a MacPro (6core, 64Gb memory) with an internal SSD. The TIFF images usually end up around 2-4GB in size. It takes a while to save the images. The progress bar reaches 95-97% very quickly and then the last 3-5% takes a while. Anyone experienced this problem?
The Mac currently runs OS10.11, I had this same issue with earlier releases as well.
