Hello,
I have a table with data in it. When someone clicks the remove button, I get the selection array and remove all the objects in it. If there is an empty selection, I am told index out of bounds, naturally, because there are no items in the array. Can I just leave this error? Or should I make a catch for it?

A truly Mac-like rule to follow is: don't enable the button if it won't work.

If the REMOVE button will cause an error message, then I should not be able to operate it.

I would suggest enabling/disabling the button when the selection changes.
