Apple Personal Diagnostics returns a low-memory alert when the APD application does not have enough memory to run or is running low on memory. For example, if you've created a report that requires more memory than is currently available. To allocate more memory to the APD application, you can do one or more of the following:
If you are using System 7, or System 6 with MultiFinder:
* Quit other applications that may be running at the same time as APD
* If you have sufficient RAM installed in your system, quit the APD application, open the Apple Personal Diagnostics Get Info box and increase the "preferred" application memory size to 1500K. (The application memory size is initially set to 1200K.)
* Close any open report.
* Reduce the size of any installed RAM disk and the system RAM cache.
If you are using System 6 with Finder rather than MultiFinder:
* Close any open report.
* Reduce the size of any installed RAM disk and the system Disk cache.
