Allocate more memory mac os x
Login items, browser extensions, and preference panes, such as Flash, are another common source of memory usage. Most of us have several installed that we rarely use, but which hog memory and reduce performance. Another way, one that is even quicker, is to employ CleanMyMac to identify and cleanup login items. Not all login items can be removed on their own.
How to take control of your Mac's memory usage
Those that can't have an "i" in place of the checkbox. Click on it to find out why it can't be removed. One common reason is being required by the application that installed it — the only way to remove it would be to uninstall the application. If you don't use the application, click on the Uninstaller tool in CleanMyMac. Check the box next to the name of the app and click Uninstall.
The app, its associated files, and the login item will be removed. Desktop widgets can provide a useful shortcut to apps you need to access fairly often. But they can take up processing memory that is slowing your whole Mac down. One way to close them completely is in System Preferences. Your desktop is meant to be a way to find important files and documents you are currently working on.
And apps you need often. And anything else that you maybe happen to need one day. Pretty soon, a desktop can look like a suitcase you've packed for every possible eventuality.

A complete mess! And impossible to find what you really need. Plus, a messy desktop can absorb valuable processing power. Either spend time manually sorting files into folders, and vowing to keep it tidy. Or use an app - such as Declutter or Spotless - to quickly arrange folders and declutter your desktop. Most startup disk drives contain a whole load of things people don't need anymore. Another problem is Adobe Flash - an application that is largely useless online due to security flaws and weaknesses.
Most videos on the web today don't need Flash. Consider that every time you use your Mac it slows down a little bit. You use more files, install more apps, and take up more storage. While going through the cleaning process described above isn't an everyday routine, try to schedule it monthly and stick to it. Your Mac will thank you for it. It is also worth fully shutting down your Mac more often.
It will perform better. Speed up and stop overheating as much when it is allowed to shut down instead of going to sleep. CPU use can have a serious impact on the health of your Mac. Not only can it slowdown and start to overheat, but if problems persist it can cause a critical failure.
Keep your Mac free of clutter and healthy. Remove folders and apps you don't need, and keep an eye on startup items, browser extensions, your desktop, widgets, and anything else that is shown as a CPU hog in Activity Monitor. Your Mac will perform at its best for far longer with regular care and cleanups.
How to reduce memory usage on your Mac
I'm not particularly technical, so it would be preferable if answers are understandable, thanks. With System 7, the Mac system software was finally made bit clean, but there were still the problem of dirty ROMs. The problem was that the decision to use bit or bit addressing has to be made very early in the boot process, when the ROM routines initialized the Memory Manager to set up a basic Mac environment where NuBus ROMs and disk drivers are loaded and executed.
Older ROMs did not have any bit Memory Manager support and so was not possible to boot into bit mode. Surprisingly, the first solution to this flaw was published by software utility company Connectix , whose product MODE32 reinitialized the Memory Manager and repeated early parts of the Mac boot process, allowing the system to boot into bit mode and enabling the use of all the RAM in the machine. Apple licensed the software from Connectix later in and distributed it for free. It was quite a while before applications were updated to remove all bit dependencies, and System 7 provided a way to switch back to bit mode if application incompatibilities were found.
At first, it would seem natural that objects would be implemented via handles, to gain the advantage of being relocatable. These languages, as they were originally designed, used pointers for objects, which would lead to fragmentation issues. A solution, implemented by the THINK later Symantec compilers , was to use Handles internally for objects, but use a pointer syntax to access them. This seemed a good idea at first, but soon deep problems emerged, since programmers could not tell whether they were dealing with a relocatable or fixed block, and so had no way to know whether to take on the task of locking objects or not.
Needless to say this led to huge numbers of bugs and problems with these early object implementations. Later compilers did not attempt to do this, but used real pointers, often implementing their own memory allocation schemes to work around the Mac OS memory model. While the Mac OS memory model, with all its inherent problems, remained this way right through to Mac OS 9 , due to severe application compatibility constraints, the increasing availability of cheap RAM meant that by and large most users could upgrade their way out of a corner.
The memory wasn't used efficiently, but it was abundant enough that the issue never became critical. This is ironic given that the purpose of the original design was to maximise the use of very limited amounts of memory.
OVERWHELMED BY TECH?
Mac OS X finally did away with the whole scheme, implementing a modern sparse virtual memory scheme. A subset of the older memory model APIs still exist for compatibility as part of Carbon , but map to the modern memory manager a threadsafe malloc implementation underneath.
