Quick question about cores


Recommended Posts

Alright so I wanna know with my Mac if I can make it use all my cores since I have two?

For example in Windows(Vista..lets say); I type in msconfig and go to boot advanced settings.. I can then change how my computers boots using both cores instead of by default one..

Is there a way I can do that with Mac??

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.

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.

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.

Here is an example of the first few seconds of the boot process on a Core 2 Duo:

The red graph is the first core, while the blue is the second. If you look closely, you can see that the second core starts being used from about 0.8 seconds and out.

Thank you

Thanks for the info; was not to sure, just read on some tweak site to make it to the number of my cores..

Ahh see I got confused then with the 1 greyed out.. I thought it was just using one..
