Using Power Macintosh application programs
Your Macintosh is compatible with most application programs intended for use with Macintosh computers. But certain programs are designed especially for Power Macintosh computers. (These are sometimes called “native” applications.) You’ll find that these programs take best advantage of your computer’s speed.
Special memory requirements
Some Power Macintosh programs 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 your Power Macintosh 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.
Shared libraries
Power Macintosh programs use special files called shared libraries. These files help the programs to run more efficiently, and can be used by more than one Power Macintosh program simultaneously. Any necessary shared libraries are installed automatically in the System Folder when you install Power Macintosh programs.
If one of these programs requires a shared library and there is not enough memory available for the shared library, you’ll see a message that the program could not be opened because of insufficient system memory. If this happens, see the “Memory” topic of Macintosh Guide, available in the Guide (h) menu, for instructions on turning on virtual memory.
If a required shared library is missing, you’ll see a message that the program could not be opened because the shared library could not be found. If this happens, follow the directions that came with your program to reinstall the program. If the shared library is still missing, contact the program’s manufacturer for assistance.
