Guides/Gridlines too thin/difficult to see on Retina display
Not sure if really a 'bug', but since upgrading to Apple Retina iMacs, everyone in my office is having trouble seeing gridlines, margins, and guides in the interface. The lines are just extremely thin on Retina displays. I have excellent vision and I find them difficult to see. Other employees with glasses are really struggling. We could really use something in the preferences to slightly increase the thickness of guides.
It's a major accessibility issue for me as my vision declines. My kingdom for a stroke width option for ruler guides. Without it I'll have to find alternative software pretty soon.
This fixes the problem:

I have the same problem. I use InDesign both on an iMac with a standard 2560x1440 display and a Retina iMac set to Best for Display (looks like 2560x1440). The guides on the standard iMac are twice as thick as they are on the Retina iMac which would suggest that InDesign is ignoring the HiDPI scaling and drawing the guides at native resolution (i.e. 5K) on the Retina iMac. I would consider this to be a bug.

I can't see them at all. Thought they were missing.
