Macs look great and are generally very easy to use. But there is one huge usability issue though. Let’s consider this message when you empty the trash:
Do you have any idea what is going to happen if you hit enter or space ?
The Cancel button is circled in blue, meaning that it is the currently focused button. It can changed with tab and activate with space.
The Empty Tash button is completely blue, meaning that it is the default button. It will be activated if you hit enter, wherever your active button is.
I know it. But every time I see such a message, I need to pause and think. Then we wonder why people always use their mouse rather than the keyboard shortcuts…
