I know that Snow Leopard comes with power management software but it's limited at best when compared to APC's "Powerchute" for Windows. APC doesn't support MAC OS X in terms of detailed management. I researched and bought an APC Back-UPS XS 1500 for my Mac Pro as it was the best hardware wise for the price, yet I'd like to have more control. Is there any third party software that allows for greater management?
