I am almost done coding my webapp-game. It runs on all modern browsers. However, I want to establish some minimum requirements for it.
Thus, I need a slow Mac. However, I don't have access to a slow Mac that has a modern browser (IE 9+, Safari 5+, Opera 11+, Chrome, Firefox 4+).
Using the tool mentioned in this question, I can simulate a slow Internet connection. I can use up plenty of memory easily. However, I have no clue how to simulate a slow CPU without resorting to underclocking.
Is there any way I can make my Mac's CPU slower temporarily without underclocking?
