I now have a 4k monitor and the toolbars and tool icons are all way too small. I read some place that updates would take care of this but when I click on updates under the help heading, I get a window saying it can't perform updates because the firewall won't allow or can't connect to the internet, etc. I temporally disabled the firewall...didn't make any difference. Connects OK to internet...still won't connect to updates. I'm not even sure if an update will fix the problem of the tool bars and such being too small. My main objective is to increase the size of all the toolbars. Going into "this computer" and changing "appearances" for text and such, changes everything else in the computer but not in Photoshop cs6.
There is no update. In CS6 only Mac has High-DPI/ Retina support. the rest we can#t help you with. You have not provided any exact info and are throwing around generics.
