I have a (non retina) 27" iMac and the text is too small to use easily. I'm 64. I could use it at a pinch but why bother with the neck and back problems squinting a lot close to the screen causes? Yes I can just see it but I work at arms length from the screen and for this it is too small to use without discomfort. I have a 7 other image editing apps and can use them all without this problem. Until this is changed I'll carry on using Ps, Lr, Photmatix, DPP (what I actually use DPP! mad or what?) Aurora (small but not as small), Helicon Focus, PTGui Pro, Imageprint, nor do I have a problem with the MacOS, so really this is the only app I have text size issues with. Point being , sure it may be usable by those with great eyesight etc but it is not the norm to expect the rest of us to be able to use it (without discomfort) so I understand there may be technical reasons why you're struggling to improve this area, but it does need improving
