Possible to make desktop icons bigger than max?
Go to Macintosh in the Finder. Once there be sure to display contents in icon view. Now while in Finder go to the View Menu and near the bottom select &quot;Show view options&quot;. This brings up the panel shown below.

Move the top slider to the right for larger icons.  You may have to move the grid slider to increase spacing as well. You can experiment with these two sliders to get the default view you want.
