Mac users from yesteryear will remember the rounded screen corners in Mac OS X. At the corners of the Menubar, for example, Mac OS X featured slightly rounded corners (which started on the original Mac back in 1984).
Since OS X Leopard, the corners are no longer rounded, they’re squared off at right angles.
Here’s the one trick pony app for your Mac that brings back those rounded corners of yesteryear. It’s called Displapature, and this is what it does to your Mac’s screen corners.
That’s it. Voila! Rounded corners.
Select which of the Mac’s four corners you want to round, select the radii, and take yourself back to days of yesteryear when the Mac’s screen was, well, rounded.
That’s about as close to a pure one trick pony app as you can get and it’s free.
