Graphics display was facilitated by the use of an expansion card with its own memory plugged into an ISA slot. The first IBM PC to use the SMA was the IBM PCjr, released in 1984. 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.
A classic motherboard with on-board integrated graphics processors, a discrete graphics card can be installed at a PCI slot. GPU switching is a mechanism used on computers with multiple graphic controllers. This mechanism allows the user to either maximize the graphic performance or prolong battery life by switching between the graphic cards.
This included a subset of configurable settings called "convenience settings" as well as other settings that adapted according to the programs and devices installed on the Lisa Office System. The original control panels in the earliest versions of the classic Mac OS were all combined into one small Desk Accessory .

It was launched on May 13, 1991, to succeed System 6 with virtual memory , personal file sharing , QuickTime , TrueType fonts, the Force Quit dialog, and an improved user interface.
The Mac Pro Server includes an unlimited [8] Mac OS X Server license and an Intel Xeon 2.8 GHz quad-core processor, with 8 GB of DDR3 RAM. [114] In mid-2012, the Mac Pro Server was upgraded to an Intel Xeon 3.2 GHz quad-core processor. The Mac Pro Server was discontinued on October 22, 2013, with the introduction of the cylindrical Mac Pro.
Apple's System 7 Tune-up addon added a "minimum" memory size and a "preferred" size—if the preferred amount of memory was not available, the program could launch in the minimum space, possibly with reduced functionality. This was incorporated into the standard OS starting with System 7.1, but still did not address the root problem. [8]
HSA defines a special case of memory sharing, where the MMU of the CPU and the IOMMU of the GPU have an identical pageable virtual address space.. In computer hardware, shared memory refers to a (typically large) block of random access memory (RAM) that can be accessed by several different central processing units (CPUs) in a multiprocessor computer system.
Apple M2 is a series of ARM-based system on a chip (SoC) designed by Apple Inc., launched 2022 to 2023.It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, the iPad Pro and iPad Air tablets, and the Vision Pro mixed reality headset.
