Using application programs designed for the PowerPC microprocessor
Your Macintosh is compatible with most application programs intended for
use with Macintosh computers. But certain programs are designed especially
for use with computers that have the PowerPC microprocessor. (These
programs are sometimes called “native” applications.) You’ll find that these
programs take best advantage of your computer’s speed.
Special memory requirements
Some native applications may be slightly larger than other programs and may
take up more memory. If you find that you are running out of memory when
you use one of these programs, you can use space on your computer’s hard
disk as additional memory. For instructions on how to use hard disk space
as memory, see the “Memory” topic of Macintosh Guide, available in the
Guide (h) menu.
You can also add more memory to your computer, as described in “Expanding
Memory” in Chapter 3.
Using older Macintosh programs
If you experience problems using an older Macintosh program, it may be
incompatible with your Macintosh. You may be able to use your older
program if you change the Modern Memory Manager setting in your
Memory control panel. For detailed instructions on using older programs
with your Macintosh, see the “Working with Programs” topic of Macintosh
Guide, available in the Guide (h) menu.
