Shared libraries
Power Macintosh programs use special files called shared libraries. These files
help Power Macintosh 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 a Power Macintosh program 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 increasing available 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.
