[44] [45] Activity Monitor appeared in Mac OS X v10.3, when it subsumed the functionality of the programs Process Viewer (a task manager) and CPU Monitor found in the previous version of OS X. [46] [47] In OS X 10.9, Activity Monitor was significantly revamped and gained a fifth tab for "energy" (in addition to CPU, memory, disk, and network). [48]
CPU activity of processes and threads. [2] Memory allocation and release, [3] garbage collection and memory leaks. [4] File reads, writes, locks. [5] Network activity and traffic. [6] This instrument works like Activity Monitor but also stores the data for future reference. Graphics and inner workings of OpenGL [7] and Metal. [8]
Here is a simplified view of the Mac OS X Tiger system startup on a PowerPC Mac (on an Intel Mac, EFI replaces Open Firmware and boot.efi replaces BootX): Open Firmware activates, initializes the hardware, and then loads BootX. BootX loads the kernel, spins the pinwheel cursor, and loads any needed kernel extensions (kexts). The kernel loads ...

The prehistory of Copland begins with an understanding of the Mac OS legacy, and its architectural problems to be solved. Launched in 1984, the Macintosh and its operating system were designed from the start as a single-user, single-tasking system, which allowed the hardware development to be greatly simplified.
Grand Central Dispatch (GCD or libdispatch) is a technology developed by Apple Inc. to optimize application support for systems with multi-core processors and other symmetric multiprocessing systems. [2]
