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. P90x stretch full video free. 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

Mac is getting slowly as more stuff is running behind and the RAM is cluttering up. By using MacBooster, you can find out which apps are the main consumers. It helps you to optimize or even close those apps taking up the memory and free up inactive memory for a faster running Mac. It still does it. I end up with around 30MB of free RAM, a reasonable amount of active RAM, and a massive amount of inactive RAM after a few days, then my computer slows down a lot. I have to keep flushing the inactive RAM with a memory cleaning tool or else my computer slows to a crawl. Repairing the permissions is supposed to clean out the. There are times that when your Mac can slow down as more stuff is running in your system and your RAM is cluttering up. When you find Mac RAM is filling up due to increased workload on the OS X then the time for a Mac memory clean tool. By using MAC Memory Clean Apps, you can get free up inactive memory for other tasks. Sep 30, 2010 At this point, I have all my free memory taken up, and only have inactive memory left. Well, when I go to open up giant image A, it takes forever to load (10 to 20 minutes) and the computer slows to a crawl - even though there are no images or any other memory sucking programs open.

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!

“No matter what I do, my Mac is still slow”, an average tech-consultant hears this phrase multiple times a day. Give a person even the most powerful computer, and pretty soon it will be cluttered with apps, extensions, and things that are too much for it to handle. To reverse it, one has to go back and сlean up the mess, removing memory agents one by one. Prepare for a fight — every byte of memory is at stake. So let’s put your Mac on a diet and get it more free RAM to breathe freely.

First, remove desktop clutter. Get a combination of Setapp apps that clear away unneeded desktop files.

“Your system has run out of application memory”

How do you know your Mac is low on memory? Floating “rainbow wheels” aside, you may notice your Mac now takes ages to load. You’ll also see many browser applications crashing. You’ll be also thrown warning messages as “Your system has run out of application memory”. To help it, you should first visit the Activity monitor to see memory usage on Mac.

How to check RAM usage on Mac

Go to Applications and type in Activity Monitor in the search bar. This invokes a good old Activity Monitor that should tell how much free memory you’ve got left.

A shortcut to open Activity Monitor:

Press F4 and start typing Activity Monitor in the search bar.

I’ve attached a screenshot from my Mac and as you can see my memory usage almost reached full capacity. Here’s what it all means:

App memory: taken by apps and processes
Wired memory: reserved by apps, can’t be freed up
Compressed: inactive, can be used by other apps
Swap used: memory used by macOS
Cached files: memory you can really use

Notice the colored graph under Memory Pressure. If your graph is all but red and yellow, your Mac is really gasping for fresh memory. It seems counter-intuitive, but “available memory” your Activity Monitor is not that important after all. In fact, it’s a system intended behavior to use all memory resources when available. On the contrary, the Memory Pressure graph is much more telling, so grow a habit to check this graph in the Activity Monitor every now and then.

How to check CPU usage on Mac

Open the CPU tab in Activity Monitor to keep in check CPU-heavy processes. Normally an app would be using 0-4% of CPU. If it takes abnormally more than that, go inside that particular item in the list and press the Quit button.

How to free up memory on Mac

Tip # 1. Remove Login Items to lower Mac memory usage

Login items are programs that load automatically upon Mac startup. Some of them covertly add themselves to the list and this is no good. If you’re looking to free up RAM, they are the first candidates for deletion. Don’t worry, you’re not deleting the app itself, you just stop it from auto-launching every time.

So, to remove Login Items and at the same time reduce your memory usage of your Mac, you need to:

1. Open System Preferences and select Users & Groups.
2. Click your nickname on the left.
3. Select the Login Items tab.
4. Check programs you don’t want to load as your Mac starts.
5. Press the “–” sign below.

Now, you won’t see these apps pop up the moment you turn on your Mac. Although this method doesn’t require some superpowers of yours, some special Mac optimization and memory cleaner tools may do the job faster and ensure the smooth performance of your Mac. CleanMyMac X is an excellent example of such software. Here’s how to disable Login Items with CleanMyMac X:

1. Download it for free and go to the Optimization tab.
2. Check Login Items to see the list of apps that get opened when you start your Mac.
3. Click Remove.

As you’ve already come to the Optimization module of CleanMyMac, you can also fix hung apps and heavy memory consumers there. In this way, you’ll free up the solid amount of RAM on Mac — 100% free of charge.

Tip # 2. Free up disk space if Mac is low on memory

The available space on your Mac’s drive translates into virtual memory. This comes to save you when you’ve run out of physical RAM. So now your computer relies on your hard drive space to keep your apps going.

The classic geek rule of thumb holds it that you should keep at least 20% of disk space on your startup drive. Not only this potentially reduces your future spending on iCloud storage but it also keeps your Mac speedier.

What to delete to free up space:

• Large unused files, like movies
• Old downloads
• Rarely used applications
• System junk

But here’s a simpler solution to save your time — clean up your drive with CleanMyMac X— the app I’ve mentioned above. Many users recommend it as an excellent way to free up more space because it searches for large & old files, useless system files, Photo junk, mail attachments and shows everything you can safely delete. Interestingly, it finds about 74 GB of junk on an average computer.

Extra trick: How to free up RAM on Mac with CleanMyMac X

If you have downloaded CleanMyMac, you may also take advantage of its amazing feature — the ability to free up RAM in a few seconds. Try this next time you see “Your system has run out of application memory” message.

1. Go to the Maintenance tab on the left.
2. Click Free Up RAM.
3. Click Run.

As simple as that!

And you can do it even if you download a free version of the app.

Tip # 3. Clean up your Desktop

This tip always comes at the bottom of instructions and unfairly so as it is quite effective. Without even looking at your Desktop I would assume it’s cluttered with mountains of icons. Thing is, your macOS was designed in a way that it treats every Desktop icon as a little active window. The more icons, the heavier memory usage on Mac. So in order to release available memory resources, it’s recommended to keep your Desktop clean.

You don’t have to do it all by yourself. With apps like Declutter and Spotless, every desktop cleaning session will be scheduled in advance and executed automatically. Your only job is to define the rules on how your files should be organized.

Tip #4. Clear cache files

Another way to free up RAM on Mac is to clear it of cache files. Of course, it won’t save you gigabytes of space, but deleting cache regularly, you can help your Mac run faster and avoid system issues.

So, to remove cache files on your Mac, you need to:

1. Open Finder.
2. From the Go menu, select Go to Folder.
3. Type ~/Library/Caches in the field and press Go.
4. In the window that appears, you will see all your cache files.
5. Press Command+A to select all files or delete files one by one.
6. Enter your user name and password to confirm.

If you find some files still in the folder after you emptied it, maybe you have some windows open on your Mac. Just like that, you can save up some space on your Mac. Don’t forget to empty the bin afterward.

Tip # 5. Tune up Chrome’s Task Manager

Minitool partition wizard rus. Although Google Chrome is not the one to blame for massive memory usage, it can indeed affect your Mac's performance. If you use Chrome as your primary browser, you probably have many windows opened there. Chrome runs a lot of processes to ensure a fast browsing experience for you. So, it uses your RAM for storing your tabs, plugins, and extensions. Look at how many entries Google Chrome has in Activity Monitor:

The question then arises, 'Why does Chrome use so much RAM?' The thing is that each process is responsible for a separate plugin or extension of your browser. For example, when a tab unexpectedly falls, you need to refresh it to continue your work there. If one process were responsible for all tabs and extensions, you would need to restart the whole browser instead. Can you imagine how many times would you do that? That’s the proper answer to why Chrome uses so much RAM.

I’ve been using Chrome for some years only to discover (recently) that Chrome had a task manager of its own. You can use it to force quit memory-heavy processes in the browser. It’s a handy tool because it lets you see how a page weighs on CPU usage on a Mac.

1. Go to Chrome settings (dotted icon in the top right corner)
2. Click More tools -> Task Manager
   

To free up even more RAM, close the GPU process. The GPU Process, though helpful in theory to accelerate pages, eats up a considerable amount of memory. Click to end it to free up RAM on your Mac.

Tip # 6. Manage RAM usage with CleanMyMac X menu

CleanMyMac X has another useful and convenient feature for managing your Mac’s performance and memory usage. As you install CleanMyMac X and start it for the first time, it’s icon will appear in your menu bar. Click the icon to open the CleanMyMac X menu. Here you can find updates on the current condition of your Mac and perform quick tweaks to increase your Mac's speed. Whenever you feel like your Mac underperforms, open the CleanMyMac X menu to check how much RAM is available and free it up as well.

Tip # 7. Close Finder windows

Okay, suppose you’re still asking yourself, how do I clear RAM on my MacBook Pro/MacBook Air. The next trick is as magical (you’ll see for yourself) as it is time-saving. It’s no secret that each window in the Finder eats up RAM. But how many open windows are there? Some of them are collapsed or stacked in some blind spot on your screen. This Finder command merges all your windows into one. See how to do it:

Click on Finder > Window > Merge All Windows

Now you can manage Finder windows more effectively and free up memory on MacBook.

What else you can do to minimize memory usage on Mac

I’ve saved the easiest tips for the end, as long as these ones are self-explanatory.

• Replace AdBlock (very memory-demanding) with a lighter extension
• Keep fewer opened tabs in the browser
• Restart your Mac more often to free up RAM
• Close all hung-up print queues

That was my take on how to make your Mac a bit speedier to use. If you’re looking for more guidance, check simple ways to speed up your Mac.
