In Mac OS 10.4 Tiger, Apple had a nice detail in the GUI, rounded corners on the screen. The rounds were small, but simulated the rounded corners of older CRT monitors on modern LCD displays. To me, though, the rounded corners meshed well with the precise radiuses that adorn the corners of Apple hardware. Apple got rid of this detail in Mac OS 10.5 Leopard and left a hard 90Âº corner with no artificial radius.
Tonight I came across a small application by Many Tricks (you may know them from their popular application launcher Butler) called Displaperture that adds radiused corners back to Leopard. An added bonus, you even get control over the size of the radius, and you can scale it from barely visible to impractically intrusive.
Considering that every Apple device sold today runs a LCD display, using this application may seem like a step backward. However, the effect looks GREAT on the new Macbook screen with it’s borderless black bezel. Setting a tight radius on the corners of the screen gives the bezel a consistant and polished look. Below you can see a picture of the effect on my Macbook Pro. It’s not for everyone, but it’s great to see such a simple free tool to set the effect.
