Mac users: Have you ever wondered what all that system memory stuff in the Activity Monitor was all about? Understanding the terminology – free, wired, active, and inactive RAM – can help you decide if your Mac has enough memory.
If the memory pressure is green you have enough memory (like the screenshot above). If the memory pressure is yellow it may be worth monitoring over a few days to see if it goes into the red. Checking your memory on older versions of Mac OS. On older versions of Mac OS the display looks more like this. How to free up memory on Mac. Knowing how to clear memory on Mac is important, especially if you have a Mac with limited resources. One option is using Activity Monitor: Open Activity Monitor on your Mac; Select an app using a lot of memory; Click the stop icon in the top bar; This is straightforward, but there's a better way. On Linux, I often use the free command to see the current amount of free and used memory in the system. For example: $ free total used free shared buffers cached Mem: 729 0 388 -/+ buffers/cache: 4284 Swap: 81264428 It does not seem to exist when I enter free in Mac OS X's Terminal. Download Memory Free 2 1.02 for Mac from our website for free. The program relates to System Tools. The bundle identifier for Memory Free 2 for Mac is memoryfreesn. The application is sometimes referred to as 'MemoryFree 2'. The actual developer of this free software for Mac is Child. This free program can be installed on Mac OS X 10.5 or later. Memory management in modern operating systems works similarly. In this case, a whiteboard is a physical memory which is shared by apps (teams). When apps request additional memory, and there is no more free space, the OS checks all memory pages. The OS tries to find ones that were not used recently and copies them to the disk.
A quick peek at Mac OS X’s Activity Monitor to see how your system is performing can generate more questions than answers. The same thing goes for free Dashboard widgets like iStat Pro. That’s because the operating system categorizes system memory (commonly referred to as RAM) in a number of different ways, rather than just “used” and “free.” There’s a bit more going on behind the scenes, so we’re left to decipher the following terms: free, wired, active, inactive, page ins, page outs, etc. If you’ve ever wondered what all of this means and how it affects the speed & overall performance of your Mac, read on!
A vocabulary overview
When a Mac’s system memory is being used, OS X doesn’t just lump it all together. It’s very neatly organized, as you will soon find out. One thing to mention beforehand, though, is that information stored in RAM sometimes gets temporarily moved to and from the hard drive when there isn’t enough RAM available. Of course, this slows a Mac down considerably, so it generally only occurs as a last resort when the system runs out of RAM. Now that we have that out of the way, let’s continue!
Free memory
As one might expect, this is the RAM that is sitting there with nothing to do. It is completely free for the system to use when needed.
Wired memory
Critical information stored in RAM by the system, its kernel, and some key application components. This stuff is basically frozen – it allocates its space and never moves to the hard drive or gets replaced with user-level data when RAM becomes scarce. An interesting thing to note about wired memory is that it scales based on how much total system memory is installed. For example, a Mac with 1GB of RAM may show 400MB of wired memory, while a Mac with 4GB of RAM may use 700MB. The more memory you have, the more your Mac wants to use it!
Active memory
Information currently in use or very recently used. If you’ve got Safari, GarageBand, iTunes, and Photoshop all going at the same time, your active memory is likely fairly high. Quit one or two of these applications and active memory will shrink. But not all of it will go straight back to free memory… some goes to the next category.
Inactive memory
One of the great things about Mac OS X’s memory management system is that it never stops working for you. Inactive memory is basically a handy storage space for convenient access to your most used tools. Let’s say you were working in iPhoto and decide to quit it. Some of the information that was stored in active memory by this application will be moved to inactive memory. This way, when you open iPhoto next time it will load up faster than before. Why? Because the computer is not reading everything from its slow hard drive again. I just ran a quick test myself to illustrate this point: After a system restart, I opened iPhoto and it took 3 Dock icon bounces to launch. I quit iPhoto, did some other stuff, and came back to it a few minutes later. This time it launched in 1 bounce.
Page ins
The amount of information moved from the hard drive to RAM since the last system startup. Every time you open an application or file, this number goes up.
Page outs
The amount of information moved from RAM to the hard drive since the last system startup. When RAM is running low or needs to be shuffled around to the hard drive to accommodate higher priority data, this number increases.
How do I know if I should upgrade my Mac’s RAM?
Now that we all better understand how our RAM is being used, it’s much easier to determine whether or not more system memory is needed. Most people look at the number next to free memory and think a low amount means they need more RAM. This isn’t always the case. As previously mentioned, active memory can get released to inactive memory when it’s no longer in use. And this is almost always a good thing, since it can increase speed and responsiveness. So low free memory is something to be happy about! Your RAM isn’t sitting there being wasted – Mac OS X is utilizing it for your benefit.
Instead, you should be concerned when free AND inactive memory are both very low on a regular basis. This situation means most of your RAM is going to wired & active memory because your running applications are demanding all of it right now. Wired & active memory hold precedence, therefore they can grab as much RAM as they need and can force free & inactive memory to give up their space.
Along the same lines, an even bigger indicator of a need for more RAM is if page outs are swelling up too. When your Mac has to keep writing information to the sluggish hard drive because it doesn’t have any fast system memory left to hold it, freezes and hangups will become common. If that’s the case, time for an upgrade!
Memory Cleaner Mac OS X First. Try These Three Ways to Free Inactive Memory on Mac OS X First, lets clarify what inactive memory is on Mac. Inactive memory is used by recently active and terminated applications. The system of your computer saves this memory in case you want to. Disk Drill: The best data recovery software for Mac OS X. Recover deleted or lost data from any storage device, iOS and Android. May 26, 2020 There is a fairly efficient Mac memory management tool that provides quick load of applications and good performance. MAC also cache things in free RAM of the system in order to quick load them from memory than hard disk for fast response. There are times that when your Mac can slow down as more stuff is.
Having computer issues like system crashes, failed booting or bad performance? This is possibly the case of faulty RAM or hardware incompatibility. To rule out the latter factor, you need to check the specification of your original RAM card and compare it with the one your purchased. More often than not, however, it is necessary to diagnose the RAM card for stability and performance issues. That’s why you’re suggested check out the best 4 free RAM test software for Mac and Windows 10/8/7 in this article.
Computer RAM Diagnostic Troubleshoot
The common symptoms of faulty RAM are beeping of PC, getting overheated unnecessarily and not working up to the desired performance marks. So, if you are facing some real issues, then you should look after them before they cause any problem or loss for you.
As we mentioned, there may be two reasons of this issue to occur. So, if your hardware system is up to the mark and if you think that there is no such issue with its compatibility, then possibly there is a fault in RAM memory card chip. You can consider some of the following points mentioned below:
- First of all, RAM memory cards are made with a perfection and quality by the tech companies. So, if you have purchased RAM from a low-level company, then there is a very high probability that RAM is a defective. Always purchase computer peripherals from named brands of this field like Samsung, Kingston, Corsair, etc.
- There is also a chance that your PC is loaded with outdated processing drivers and chipsets. So, kindly upgrade them to their latest version to use new RAM chip in your PC.
- There is also a probability that the CPU coolers of your PC is not working properly which results in the overheating. Please check the CPU coolers and if they are not working properly.
- Incompatibility of PC’s hardware with the RAM chip may also raise this issue. Because users just purchase RAM of higher memory without analyzing the hardware compatibility of their PC with it, that’s why this issue rises.
- Another very common issue is the lack of knowledge among the users. Sometimes, users insert the RAM chip in the wrong slot which results in this issue. Make sure to insert the RAM chip inside the slot which is reserved for it.
Pro tips: Special attention should be given to the above factors, otherwise data loss could happen once there is system error. If you have unluckily lost precious files, don’t hesitate to use Jihosoft File Recovery Software to recover lost files from Windows 10 or Mac.

System cleanup in one click
Forgotten city skyrim guide. Few things are more frustrating than your Mac telling you it has run out of memory when you're trying to be productive. It's more frustrating when you've ignored the problem for quite some time and your Mac's limitations simply won't let you put a solution on hold any longer.
- How to get rid of low memory notifications
Kellenberger grinder manual. Usually, a popup warning isn't the first sign that something is amiss. You may have noticed that your Mac isn't running as fast as it used to, with the fan louder than normal as if it's struggling to carry a heavy load up a hill.
Although Macs are wonderful computers, they have limitations. Thankfully, there is plenty you can do to resolve this problem and get your Mac operating smoothly again.
Reduce memory usage with Setapp
Instead of manually deleting files, get Setapp. It not only removes the clutter but also gives you full control over memory usage.
Your system has run out of application memory - Fix it
Mac memory usage is often occupied by apps, even browsers like Safari or Google Chrome. In the most dire circumstances, your Mac will toss a warning at you: 'your system has run out of application memory.'
Don't despair – it's solvable. The first thing to note is this is a natural issue; your Mac has a limited amount of RAM. Though more expensive Macs have more RAM, even they can butt against limitations when too many applications are running.
It may also be an app that is hogging all of your resources. This is especially true of older applications which haven't been optimized for modern computer architecture. Websites may also be a culprit.
Check RAM usage on Mac
To check your RAM use on any Mac, take the following steps:
- Open Activity Monitor from your list of applications
Note: You can do this is the Mac's control center, via the Finder in your Mac's dock, or by pressing command-space and typing 'Activity Monitor' in the Spotlight search field. - Toggle to the 'Memory' pane in the Activity Monitor window
As you see in the above screenshot, Activity Monitor shows you all of your processes, sub-processes, and how much memory each is taking up. The most pertinent portion of the window is the bottom, where it shows you the total memory usage, and how it's affecting your Mac.
A better way to monitor your Mac's memory use is with iStat Menus. After installing the app, it makes a home in your Mac's menu bar, and monitors just about everything, including memory, CPU, GPU, disks, and network usage.
You can choose which systems you'd like to monitor in the app itself. Only the items you're monitoring will have an icon in your menu bar. A simple click on the menu bar icon surfaces a drop-down menu of how your Mac is performing at the time, and hovering over each graphic brings up a larger menu, as you can see below.
How to check CPU usage on Mac
Checking CPU use on your Mac is similar to the steps above for checking memory use. For Activity Monitor, you'd make sure to highlight the 'CPU' section of the window. This will show you all the processes using your Mac's CPU at the time.
Similarly, iStat Menus has a 'CPU & GPU' toggle just above the memory section. Activating that will add a CPU and GPU monitor to your Mac menu bar, which has the same interactivity as the memory icon and menu shown above.
How to free up memory on Mac
Knowing how to clear memory on Mac is important, especially if you have a Mac with limited resources. One option is using Activity Monitor:
- Open Activity Monitor on your Mac
- Select an app using a lot of memory
- Click the 'x' icon on the top left of the screen
This is straightforward, but there's a better way. CleanMyMac X has an automated CPU and memory monitors built-in, which can give you a real-time view of memory usage in your Mac's menu bar. It also has a really quick and easy way to free up memory without digging through Activity Monitor and manually shutting down apps.
All you have to do is click the CleanMyMac X icon, select 'Free Up' in the memory pane, and the app takes care of the rest! Oftentimes, it doesn't even shut apps down.
This is a quick fix, but CleanMyMac X takes it a step further in the app itself. Under the app's 'Maintenance' section is an option to 'Free Up RAM,' which helps you clear RAM on Mac. Once you've got this option selected, simply select 'Run' at the bottom of the window, and CleanMyMac X will do a thorough scrubbing of your Mac's RAM, and clear unused files out of the way.
How to get rid of low memory notifications
Most apps are pretty good about how they use your Mac's resources. Having too many open or running in the background can severely limit what your Mac can handle, and is often why a Mac overheats or slows down.
Here are a few tips to reduce high memory usage manually if you're experiencing unique warnings or issues:
Fix 'kernel_task', a high CPU usage bug
You may have noticed through Activity Monitor something called kernel_task absorbing a large amount of processing power. One of the functions of kernel_task is to help manage CPU temperature; you may find that your Mac fan is loud and always on, even if the device isn't hot to the touch.
kernel_task usually performs this way when one or more applications are trying to use too much CPU. Unfortunately, one of the potential downsides is a Mac can overheat to such an extent that internal systems are damaged, sometimes irreparably.
Working through the following steps in this article is one way to avoid similar problems. If none of this work and kernel_task is still absorbing a high percentage of your CPU, then one or more of the following could be the cause:
- Cooling system inefficiency
- A failed or disconnected temperature sensor
- Another hardware issue, including a worn out batter
- Your System Management Controller needs a rest
If you're experiencing severe issues, Apple recommends a system management controller (SMC) reset. It's essentially a hard reset for your Mac, and should help your RAM and other hardware components start from scratch. Keep in mind you won't lose any data in this process.
Reduce memory usage in Finder
One common culprit for RAM issues is Finder, your Mac's file manager. If iStat Menus or Activity Monitor has highlighted Finder as using hundreds of MBs of RAM, there is an easy solution: change the default display for a new Finder window so it doesn't show All My Files.
- Click on the Finder icon in the Dock and click on the Finder menu, then select Preferences
- Click on General. Under 'New Finder windows show', click the dropdown menu and choose any option except All My Files
- Close Preferences, press Alt-Control, and click on the Finder icon in the Dock. Click Relaunch
Finder will now relaunch with new windows opening at the option you selected in step two.
Improve Chrome's Task Manager
Chrome is a popular browser, but it's a resources hog! Chrome uses a GPU Process as standard, which means it speeds up the loading of web pages, which can be great except at times when your computer is struggling with insufficient RAM.
Here's how:
- Open Chrome on your Mac
- On the right side of the Chrome window, select the three-dot menu
- Select 'More tools'
- Select 'Task Manager'
- Select a Chrome process you'd like to kill
- Select 'End Process' at the bottom right of the window
Here's another way to reduce Chrome's use of your Mac's memory:
- Open Chrome on your Mac
- On the right side of the Chrome window, select the three-dot menu
- Select 'settings'
- Scroll to the bottom of the page and select 'advanced'
- Scroll down to 'System,' and toggle 'Use hardware acceleration when available' off
This will affect how Chrome runs on your Mac, and your experience won't be as smooth. You can also remove unused or unwanted Chrome extensions to help it use less resources on your Mac.
Get CMM X to free up space
Install CleanMyMac X and streamline the entire process of memory management on Mac. Clever memory usage control done for you.
Clean up browsers
In every browser you use regularly, there are always going to be extensions and popups that take up space and use RAM. You can manage each one manually, or use a tool such as CleanMyMac X to identify and delete them.
In the CleanMyMac X app is a section titled 'Extensions,' which lists each extension you have for your browser or browsers. All you have to do is view the list of extensions, select the ones you no longer want, and remove them. It's really that simple!
Disable login items
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.
Memory Free For Mac Osx
One way to do this is through System Preferences:
- From your Mac menu bar, select 'System Preferences'
- Select 'Users & Groups'
- Select 'login items'
- Deselect items you no longer want active at login
Another way, one that is even quicker, is to employ CleanMyMac to identify and cleanup login items.
- Open CleanMyMac X
- Under 'Speed,' select 'Optimization'
- Select 'login items'
You can remove all login items, or select the ones you'd like to remove individually on the right side of the window.
Disable desktop widgets
Memory Free For Mac Os
Older Macs running a version of macOS older than Catalina can disable widgets. 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.
Go to: Mission Control > switch off the Dashboard
Declutter your desktop
Apple's built in decluttering tool is handy for many. All you have to do on your cluttered desktop is right-click, then select 'Use Stacks.' This places all of your desktop files into folders unique to their filetype, like 'screenshots' and 'images.'
Mac Os Free Memory Pack
A better way is to use Spotless, an app that gives you far more control over how your Mac is organized. It has several triggers for automated cleanup of files on your desktop, placing them wherever you see fit. It's particularly useful for power users who produce several files daily, but don't want to take the time to place each in a respective folder.
Memory Freer For Mac Os
You can also select many files on your Mac desktop, and tell Spotless to tidy them up. You always have full control!
Schedule regular cleanups
Constant use of your Mac, or leaving it on all the time, will slow it down over time. Shutting it down and restarting is a traditional way of 'cleaning up' a computer.
We also like CleanMyMac X's scheduled cleanup feature. Telling the app when you'd like to perform a thorough cleaning up of your Mac's system is a method many prefer to shutting down and restarting often. It has the upshot of removing files and folders you no longer use, and cleaning up tasks that are slowing your Mac down behind the scenes. A simple shutdown may not do this.
Keeping your Mac in tip-top shape is critical. While we'd all like to think computers are brilliant little devices that can handle anything, they need some care, too.
All of the apps mentioned in this article help with taking care of your Mac, and protecting your investment. Best of all they're each free as part of a seven day trial of Setapp. Give it a try today!
Memory Free For Mac Computers
Meantime, prepare for all the awesome things you can do with Setapp.
