### Do I have an Intel or PowerPC Mac?

PowerPC (PPC) Macs are Apple's older line of machines with Motorola chips. Macs purchased since 2006 are almost all Intel. To find out for sure:

* Click on the Apple menu in the top left corner of your screen.
* Select "About this Mac."
* It should have a line that starts with "Processor." If somewhere in that line it says "Intel," then you have an Intel Mac. Otherwise, you have a PPC Mac.

For more information, see the [Apple Transition Timeline](http://en.wikipedia.org/wiki/Apple%E2%80%93Intel_transition#Timeline) or the [exhaustive list of Macintosh models](http://en.wikipedia.org/wiki/Timeline_of_Macintosh_models#2000s) on Wikipedia.
