To avoid this or address the issue as it arises, it is recommended to run Mac optimization apps such as CleanMyMac to free up space by eliminating junk and cached data from the computer. If the startup disk doesn't have sufficient space to create new swap files.How does this relate to app memory failure? Well, this usually happens under two circumstances: To maintain control of these pages, the processor and its memory management unit (MMU) maintain a page table. This allows macOS to step beyond the limitations of physical RAM by creating a logical address space (or вЂvirtualвЂ™ address space) for each process and divide it up into uniformly sized chunks of memory called pages. There is a twist with macOS, though: the space allocated to apps and their processes can be higher than the available physical memory, which is where вЂvirtualвЂ™ memory comes in вЂ“ and is the reason why it is called as such. It includes three subcategories: app memory, wired memory, and compressed memory.ДЄpp memory defines the total amount of RAM used by the applications and their processes, while the wired memory is the amount of memory that cannot be compressed or paged out to the startup drive.

The memory used category displays the total amount of memory currently in use by application and system processes.

Upon launching Activity Monitor, users will be presented with a memory pressure graph (or pie chart in OS X Mountain Lion and earlier), and next to that graph there is a breakdown of the available memory resources in three categories: memory used, cached files, and swap used. This space is defined by Apple as the virtual memory of the application and is one of the key characteristics of the application as a process: all its threads will share the same virtual memory space.ДЄctivity Monitor, or even third party apps such as iStat Menus, provides users a great overview of the current status of memory usage. Ideally, the memory space where the application operates is isolated from other applications, providing more stability and security. The more limited the hardware, the bigger the effect of this memory pressure. When an app is launched, its code, data, and processes are loaded into the physical memory of the Mac, in doing so increasing the memory pressure on the hardware resources of the computer. We are aware of the extra cost that comes with installing optional physical memory to reach the hardware limits, but it's the best investment that can be made because that's one of the secrets to extending the lifespan of that Mac.

When on a limited budget, maxing out the RAM is best postponed for a secondary upgrade cycle, if applicable. At the moment of purchase it is best to max out the amount of physical memory the machine supports, but that obviously pushes up the final price.

So what happened exactly? Does this mean the Mac doesn't live up to Apple's promise of delivering the best computing experience, with software and hardware working together in perfect harmony? Well, hereвЂ™s everything you need to know about application memoryвЂ¦ macOS and Memory ManagementД®very Mac is equipped with limited hardware resources, which in this case is the RAM. macOS then suggests quitting applications you're not using to avoid problems with the computer. The symptoms are an unresponsive Mac, high memory pressure, and a dialog box appearing with a вЂњYour system has run out of application memoryвЂќ message.

Isn't Inactive memory a waste of resources?Д«y the sheer number of 'inactive memory' questions, you can focus on the part of OS X's memory management that is most puzzling to people and hence gathers the most questions here looking for explanations.Running out of application memory is the last thing you want when using a Mac, but it may happen in some cases, usually when you aren't expecting it вЂ“ at least, according to Murphy's law.

Trouble Understanding Inactive Memory in MacOSX.

Can I force my Mac to make better use of the inactive memory?.

What does it mean if I have lots of 'Inactive' memory at the end of a work day?.

You'll probably have to do the synthesis of how OS X compares to the other two OS as I haven't seen that answered here to date.ДЇocus on the virtual-memory and os-x tags for the best results in your searching: If that is too low level for your paper, we have easily 10 or more good questions covering more of a non-programmer's view of OS X memory management. Since that kernel was developed by Carnegie Mellon University, you can find dozens of papers describing it quite easily.

Apple documents the lowest levels of the Mach Kernel and the virtual memory subsystem fairly well on the web as part of it's developer documentation.
