Optimizing your Macintosh system configuration
If you are starting Cabri Geometry II on a Macintosh for the first time, you may need to make some
adjustments to make Cabri Geometry II compatible with your Macintosh computer system
configuration.
Graphics intensive programs require a large amount of memory to operate. The amount of memory
required directly relates to the size of your monitor and to the number of colors chosen to
represent graphical elements. Cabri Geometry II may require more memory than other applications
due to its interactive nature. Cabri Geometry II can assist you in optimizing your system.
If you see a warning message from the Finder , you need to make some adjustments to your system
configuration. This message indicates the amount of memory needed to run Cabri Geometry II
efficiently on your computer with your current configuration.
Click the OK button to proceed (Cabri Geometry II does not start). Then close any applications or
windows that are currently open. This frees the memory that these applications are using.
To change the amount of memory allocated to Cabri Geometry II, first make sure the Cabri II icon is
selected. Then, from the Finder , select Get Info in the File menu. Once the Get Info window appears,
decrease the application memory size to a value that is compatible with your computer.
If you are using System 7, an optional method is to use Virtual Memory to increase the amount of
memory available to applications. See your Macintosh User's manual for more information.
The previous dialog box indicates the amount of available memory on your computer. You may
also select About this Macintosh in the Apple menu for the same information.
Changing your Macintosh system configuration using Cabri II
If you open Cabri Geometry II and the memory allocation on your Macintosh is not optimal, the
following dialog box appears. We recommend that you allow Cabri Geometry II to select optimal
parameters for your system automatically or that you select them using the Manual button.
You may wish to quit and modify the settings yourself if you are familiar with the memory and
monitor control panels.
If you select the Automatic button, Cabri Geometry II computes the optimal settings for your
computer and then quits. The number of colors may change in the process of optimizing your
configuration. Double-click on the Cabri Geometry II icon for the changes to be applied to Cabri
Geometry II.
If you select the Manual button, Cabri Geometry II continues to the optimization dialog box (see
example on the next page) that allows you to optimize your configuration as you want. Read the
items in the Current Settings field first, and then manipulate the other fields as described below the
example. (You can also access the following dialog box by pressing the
the software.)
