Icon size

[Anonymous]

Using AC 19 on Mac El Cap on 27 Inch Imac, display at 2560 x 1440.

I am finding the Icons, Toolbars and Palettes just too tiny and hard work to select.

How do I increase toolbar and palette size without changing the screen resolution. This resolution is ideal and fine for drawing.

In W7 I used the 125-150% accessibility settings and it worked well.

Cant see a similar setting on Mac El Cap and so looked for similar within AC - surely this must be possible ?

Any help gratefully received
