I have a 16" mac book pro. The bottom of the Photoshop image window is below my screen view. I cannot shrink my Photoshop window! I tried changing the Display what else can I do?
You cannot size the image window from any corner but the bottom right corner in Photoshop on a MAC
That was true for many years...but not anymore. Adobe started allowing window resize from any edge (not just any corner, but any edge) a couple of versions ago, on the Mac, to match Windows. On top of that, in OS X Lion, Apple itself now allows window resizing from any edge in any application. That said, even in Lion, I noticed that I had to move the Photoshop CS6 window edges away from the monitor edge before I would get the double-arrow resize pointer. Not sure if that's a bug. Here's a picture of what Photoshop window resizing looks like:
Also, if resetting workspaces doesn't work, you could try a complete Photoshop preferences reset. Start Photoshop CS6 and press Command+Option+Shift, and a reset dialog box should come up. Click OK.
