In reference to installation CDs or binaries, Universal refers to its ability to run on both PowerPC and Intel-based Macs. PowerPC binaries can only be run on Intel Macs via emulation, which can be quite slow.

What is a PowerPC Mac?

Hi, PowerPC mac is a mac computer that has a powerPC processor. Note PowerPC = Power Performance Computing(Not Personal Computer!)


Can you use a Intel app on PowerPC Mac?

Yes and no. You can run Windows software on a PowerPC Mac using software such as VirtualPC for Mac or Q. A powerful Mac is required to do this as emulating a completely different CPU with a completely different architecture is VERY CPU taxing. However, running an Intel app on a PowerPC Mac is impossible. The code inside of the program is written for the Intel chipset and not PowerPC. If you find a "Universal" porgam, that means that there are two sets of code in that program, PPC and Intel.


What is the significance of the universal symbol of Appl's Mac application program?

When you see the Universal symbol on Mac applications, that means they're made to run on both Intel- and PowerPC-based Mac computers. Simply install them as usual. They'll automatically run at peak performance for your Mac's architecture. And, it bears repeating, if your Mac is powered by an Intel processor, that performance will be nothing less than astounding - up to 4X what is possible on PowerPC-based machines.
