The Mac takes full advantage of both cores in the background.
I use MenuMeters on my system and it shows both being utilized at the same time. What you can do is install the Processor Preference Pane
Instructions Here...This will let you see both Cores as well as the utilization.
Thank you

By the way, just to clear something up....the msconfig changes in Windows are so you can DISABLE a core during boot, not enable all during boot. By default, all cores are used during bootup.
Thanks for the info; was not to sure, just read on some tweak site to make it to the number of my cores..

The whole premise is flawed.
The default is not 1. The default is grayed out, as in nothing picked, as in automatic. It is a debugging feature designed to reduce the number of processors. Manually setting it to the number you have won't make your system any faster. On the default settings, both cores will start almost immediately after you boot. Anyone who claims otherwise can show me screenshots of their boot progress in xperf, and I will eat my words.
Ahh see I got confused then with the 1 greyed out.. I thought it was just using one..
