When programs perform tasks on OS X and other platforms, chunks of memory are allocated for their needs, but these should be relinquished when the task is done. If not, then a memory leak may occur, where progressively more memory is reserved (sometimes at a rapid rate), until the system cannot allocate anymore and is strained for resources. When this happens, the entire system may run slow, pause, or hang and require a forced restart. Unfortunately there is little you can do as an end-user to prevent a memory leak, but with quick identification you can knock out a program that is causing one, before it starts affecting the entire system.
Memory management has always been a meticulous frustration for programmers to both implement and track in their code, and Apple has taken great efforts to centralize this and keep less on the shoulders of developers. However, underneath all of Apple’s code there is still the requirement for memory management somewhere, so if a bug exists, then some nuance handling of code can still result in a memory leak.

“Your system has run out of application memory.” This message appears and the entire system becomes unresponsive. The window includes the option to force quit apps, but gives a beachball when I attempt to do so. Can’t open activity monitor to identify a potential memory leak at this point. Requires a forced reboot. Nov 27, 2018 So I have to wait however long it is for a dev to answer my JIRA report. However in the FS Support Group, I'm apparantly not alone with the rampant memory leak issue. According to some other users I spoke to, they also are experiencing high memory usage on both Mac and Windows 10.
Mar 03, 2013 Thanks for the useful info. My app mainly uses DirectX and I am guessing the main leaky part is there. It is a huge stack and I do not think I can find leaks by getting memory usage snapshots in different points. I need a tool to tell me the allocated but not released memory. Oct 27, 2014 The updated Mail app appears to be the culprit of the memory leak that is triggered whenever multiple files are dragged into an email to be added as attachments. Over 100 hundred users have. Jan 10, 2018 Ah, yes, the dreaded “Your system has run out of application memory” error in MacOS X. It’s not a problem that comes up too often because being built on a Unix foundation, Mac OS X actually has decades of memory management evolution under the hood, but sometimes you can get a program that gets bigger and bigger in memory and causes problems.
If any process begins to climb up the list without stopping, then keep an eye on it. This is generally normal behavior, especially as you use your system; however, if this continues to where the process is at the top of the list, with its Memory footprint continuing to climb, then this may be fair indication that a memory leak is occurring.
This type of judgement can be difficult, but if memory management does get out of hand to the point where it may destabilize the system, then you will see a few tell-tale signs:
Unused programs closing
If you have some programs open but are not using them, then OS X may shut them down to free up resources for the ones you are using. This feature is called Sudden Termination, and can be hard-coded into programs by developers. When this is used, the only indication it has happened is the program will disappear from the Dock. This may repeat if you re-open the program and then change to another so the opened one is put in the background.

The force-quit window may show up, claiming you are out of memory and showing applications being paused.
This feature being used does not mean you have a memory leak, but indicates your Mac is low on memory and is making accommodations. If you see this, then it is a good time to open Activity Monitor and see what programs are using the most memory.

Out of Memory errors
If this happens, you will see a system warning display that mentions a program or the system is out of memory. This usually means the system’s virtual memory (the management system that collects all hardware capabilities and presents them as usable memory space for programs) is pushed to its limit and can no longer organize hardware capabilities to accommodate the tasks you are running.

The Force-Quit window suddenly appearing
When the system is dangerously low on resources, OS X will display the force-quit window, which may state the system is out of memory, and which also may show applications in a paused state. This is a last ditch effort by OS X to keep the system running in the face of this memory error, and means you may have only a short time before the memory leak overtakes the system and causes an entire system freeze.
How To Find A Memory Leak
Red processes in Activity Monitor or the Force-Quit window
Memory Leak Definition
In the force-quit window, any paused processes or those not responding will be displayed in red; however, this will not tell you what processes may be causing the issue at hand. To do this, return to the Activity Monitor utility, where you can list the processes by memory usage, and determine which are taking up your system’s memory. You can then select these processes and force-quit them to clear the problem. Note that if you are seeing a number of “Safari Web Content” processes that are showing problems, first try force-quitting Safari itself before acting on these individually. This should close all of the Web Content processes that are running within Safari.
A series of paused processes in Activity Monitor that are using a huge amount of memory (notice Mail at the top of the list, using 52GB of memory) suggest a massive memory leak, as opposed to another error like an application hang.

Overall, memory leaks are as old as computer programming itself, and while there are massive improvements to the way memory is handled, and while such bugs should be at a minimum, they are inherent to computers and may happen for numerous reasons. To tackle them when they happen in OS X, the above procedures will work, but there is ultimately no way to prevent them. Your best bet for prevention is to simply keep your software up to date, and notify developers if you have experienced what you think is a memory leak, so a patch can help prevent it from being an issue in the future.
