"About This Computer" Mac OS 9.1 window showing the memory consumption of each open application and the system software itself. Historically, the classic Mac OS used a form of memory management that has fallen out of favor in modern systems. Criticism of this approach was one of the key areas addressed by the change to Mac OS X.
Video memory was shared with the first 128 KiB of RAM. The exact size of the video memory could be reconfigured by software to meet the needs of the current program. An early hybrid system was the Commodore Amiga which could run as a shared memory system, but would load executable code preferentially into non-shared "fast RAM" if it was available.

Either the processor or the video/sound engine could access the memory, but not both, resulting in up to a 10% loss in performance; the DMA circuit also performed necessary maintenance on the RAM which would otherwise add overhead, a trick previously used in the Apple II. Precise timing information was relayed to the 68000 by interrupts. The ...
