'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.

'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:
- Open System Preferences and select Users & Groups.
- Click your nickname on the left.
- Select the Login Items tab.
- Check programs you don't want to load as your Mac starts.
- 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:
- Download it for free and go to the Optimization tab.
- Check Login Items to see the list of apps that get opened when you start your Mac.
- 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:
Mac Os Download
- 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.
- Go to the Maintenance tab on the left.
- Click Free Up RAM.
- 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.
Wellout mac os. 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:
- Open Finder.
- From the Go menu, select Go to Folder.
- Type ~/Library/Caches in the field and press Go.
- In the window that appears, you will see all your cache files.
- Press Command+A to select all files or delete files one by one.
- 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
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.
- Go to Chrome settings (dotted icon in the top right corner)
- 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. Hyngan mac os. 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. New free casino slot games. 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.

How to remove WARNING! MAC OS Is Infected from Mac?
What is WARNING! MAC OS Is Infected?
'WARNING! MAC OS Is Infected' is a fake error similar to Apple Security Alert, Apple Support Center - Attention!!, Apple Warning Alert, and many others. This error is displayed by a malicious website that users often visit inadvertently - they are redirected by various potentially unwanted programs (PUPs). These programs also deliver various 'malvertising' ads (pop-ups, banners, coupons, etc.), record information (mostly, about web browsing habits), and misuse system resources.
This error states that the system has been infected and that the malware must be removed and system repaired immediately. Users are advised that they must not hesitate to call Apple technical support via the telephone number ('1-844-658-5859') provided. Certified technicians then supposedly guide users through the malware removal process. Bear in mind, however, that 'WARNING! MAC OS Is Infected' is a scam. This error is fake and has nothing to do with Apple. In fact, cyber criminals claim to be certified technicians and attempt to monetize their services that are not needed. In addition, these people often trick users into granting remote access to their computers. Once connected, cyber criminals stealthily install malware and/or change system settings. Then they claim to detect additional errors and offer further help for an additional fee. Therefore, we strongly advise you to ignore 'WARNING! MAC OS Is Infected' and to never call the aforementioned telephone number. This error can be removed by closing the web browsing or rebooting the system. Be aware that some malicious websites and PUPs mine cryptocurrency or run other unwanted processes in the background. They misuse system resources without users' consent, thereby significantly diminishing overall computer performance. Potentially unwanted programs are also known to gather various information that might contain personal details. This data is sold to third parties. Furthermore, PUPs often deliver malicious ads using various tools that enable placement of third party graphical content on any site. Therefore, the ads usually conceal underlying content, thereby diminishing the browsing experience. Malicious ads may also lead to rogue websites and/or execute scripts that download and install malware. Therefore, even accidental clicks can result in high-risk computer infections. For these reasons, we advise you to uninstall all potentially unwanted programs immediately.

Damage | Internet browsing tracking (potential privacy issues), displaying of unwanted ads, redirects to shady websites, loss of private information. |
Malware Removal (Mac) | To eliminate possible malware infections, scan your Mac with legitimate antivirus software. Our security researchers recommend using Combo Cleaner. |
As mentioned above, 'WARNING! MAC OS Is Infected' shares many similarities with dozens of other fake errors. Each and each one claims that the system is damaged , however, these false claims are merely attempts to extort money from unsuspecting users. Potentially unwanted programs are also very similar. By offering various 'useful features', PUPs trick users into believing that these programs are legitimate and useful, however, that all potentially unwanted programs only generate revenue for the developers. Therefore, only very few give real value for regular users. Most merely promote rogue websites (unwanted redirects), deliver malicious ads, gather information, and misuse system resources. These programs pose a direct threat to your privacy and Internet browsing safety.
How did potentially unwanted programs install on my computer?
Research shows that some PUPs have official download websites, however, most are distributed using a deceptive marketing method called 'bundling', and via the aforementioned malicious ads. Therefore, users often install PUPs inadvertently or PUPs stealthily infiltrate their systems without permission. Bundling is stealth installation of third party software together with regular apps. Developers hide bundled programs within the 'Custom/Advanced' settings or other sections of the download/installation processes. Many users are careless during download and installation - they rush and skip steps. In addition, many users click various ads. This behavior often leads to inadvertent installation of potentially unwanted programs.

How to avoid installation of potentially unwanted applications?
The key to computer safety is caution. Therefore, pay close attention when downloading/installing software and browsing the Internet in general. If possible, select the 'Custom/Advanced' settings, carefully analyze each window of the download/installation dialogues, and decline offers to download/install third party programs. Bear in mind that third party download/installation tools are monetized by promoting dubious programs (the 'bundling' method). Therefore, we recommend that you avoid using such tools - your software should be downloaded from official sources only, using a direct download link. Most malicious ads appear legitimate, as developers invest a great deal of time and money into their design, however, these ads are distinguishable for their redirects - most lead to survey, adult dating, pornography, and other similar sites. Therefore, if you encounter this type of ad or website, immediately remove all suspicious apps and browser plug-ins.
