How to Make Your Slow Mac Run Faster

run mac fast

As you have had a MacBook Air, MacBook Pro, iMac, or Mac mini for years, you must experience your Mac running slow and freezing. There are credible reasons why your Mac is not running as fast as expected. These may include age factor; a full hard drive; you’re operating with an outdated macOS; too many apps launching during your Mac’s startup; too much background activity; your hardware being old; your desktop being like a file dump, your browser junk-filled, numerous outdated cache files, too many large and old files, duplicate files, and so on.

Ways to Make Your Mac Run Faster

Many things have been done to help a slowly running Mac to run faster. All the methods below you can have a try and decide which one will help you most.

Age Factor

Macs become slower the more they are used and as they age. Not to worry though, there are things you can put in place to help motivate your Mac to work faster.

Full Hard Drive

It could also be that your hard drive is getting full. Nothing makes Mac slow down more than a full hard drive. If you free up its space, as well as clean up all cache and junk files, then surely its speed will be improved. To clean up your Mac fast, Mac Cleaner is the best app to help you make your Mac clean and fast in one click.

Outdated MacOS

Another reasonable cause of your Mac running slow could be that your Mac’s operating system is outdated. Updating it would solve that problem. Apple releases a new OS X every year. But you can be certain that there are newer versions of the operating system than the one you are currently using. So, what you need to do is to switch to a new macOS version.

If recently your MacBook is running slow after the macOS Mojave update, disk permissions may be broken. You can repair them with Mac Cleaner. Download it and go to the Maintenance tab, click “Repair Disk Permissions”.

Slow Startup

What slows down your Mac’s startup is simply a load of things booting in the background. Sadly, they don’t stop even after the macOS is up and running. What you need to do is reduce the number of items that would be launching during startup. Go to your “System Preferences > Users & Groups”, click on your username; click on “Login Items”; click on the application that doesn’t need launching during startup; click the “-” that appears on the left-hand side, below the list – this will remove the app from the list. This will go a long way in increasing your Mac’s startup speed.

There is another way to manage your startup items with Mac Cleaner. First, download and install it on your Mac. Then click “Optimization”  > “Login Items”. You can selectively disable the apps you don’t want to automatically launch every time you log in to your Mac.

Background Activity

When there are too many background activities, it will slow down the Mac system so that even simple tasks become difficult to perform. To fix this, put an end to unnecessary activities with the Activity Monitor. Quit apps you are not currently using because it will go a long way in speeding up your system. First, open your applications folder, and then open the utility folder. You will see the Activity Monitor there, and open it. Peruse it to check the apps and processes loading on your Mac. You’ll be able to understand why your Mac is running slow in this way. Stop any unwanted app by clicking the gray “x” icon at the top left corner of the window. Be careful and only remove what you know.

Desktop Is A File Dump

If I ask to borrow your Mac right now and I start it up, what would I find on the desktop? Sometimes the desktop may be so cluttered with applications, documents, and folders. What most people don’t know is that this is a very effective way of slowing down a Mac. If you want to improve the performance of your Mac, you can try these ways: reduce the applications you pack on your desktop; organize your files into distinct folders and then move them to another location in the folder; uninstall unwanted apps and send them to trash bins. But don’t forget to empty the Trash bins, as too many files in the trash bins take up space as well as affect the system performance.

Junk-filled Browser

If there are too many opened tabs and extensions on your browser, your Mac will definitely be slow. What I’m saying is: if your browser is hanging, it is because it is overloaded. And if the browser is overloaded, then the system will be overloaded. To fix it, you need to close the tabs and remove the browser cache or extensions. The extensions often come as disguised software. Perhaps you just download something and then what you will see are pop-ups and ads here and there. They are good but they put a burden on your browsers and system. Moreover, they subtly eat up your data and memory. To remove extensions, click the three-dot icon on the top right corner; click More tools > Extensions. An overview of all the add-ons you installed will appear. Just go ahead and delete them if you are sure you do not need them anymore. If you still need them, you can just disable them. If you want to remove all extensions of Safari, Chrome, Firefox, and other apps, Mac Cleaner provides a powerful way to scan all extensions on your MacBook and help you remove them in seconds.

Outdated Cache Files

Research, it is discovered that cache files make up for about 70% of junk on your Mac. To manually clean up cache files on Mac, open “Finder” and click on “Go to Folder” in the Go menu; then locate the cache folder. Open it and delete the files in it. Then go to the Trash bin and empty the Trash. If it seems a little complicated, you can try Mac Cleaner, which is very easy to clear cache files on Mac. Importantly, it won’t cause any problems to your MacBook after you wipe out cache files with Mac Cleaner.

Large & Old Files

When there are piles of large and old files on your Mac, it will take up much space and slow down your Mac. In order to prevent your Mac from a reduction in its performance, getting rid of large and old files will be a necessary way to free up your Mac. Mostly you can find the large and old files in the Downloads folder and Trash. You can just move the files to the Trash and empty the Trash. But if you want to search all the large and old files on your hard drive, Mac Cleaner is the best way to find them in seconds over your Mac. In the scanning result, you can select the files you don’t need anymore and remove them permanently in one click.

Duplicate Files

Sometimes you download the same pictures or files to your Mac twice, and you will save two same files on your MacBook, but there is no need to keep them on the hard disk. Duplicate files will occupy double or more space on your Mac hard drive but they are hard to be found out because duplicate files are among different folders. In this case, in order to search for all duplicate files on Mac, you can get the help of the Duplicate File Finder, which is designed to look for duplicate files easily and fast. And you can just delete the duplicate files to keep the best one on your Mac. It will save you time and help you save space on your Mac.

Old Hardware

Unfortunately, while aging software can be amended, the same cannot be said for hardware. When Mac becomes too old, its speed drops so low it’s frustrating and there is little you can do about it! If you’ve updated your operating system, freed up space on your Mac, cleared up background activities, and managed your startup items and your Mac is still sluggish in performance, then you might want to consider upgrading your hardware. That can involve buying a larger RAM for your Mac. For instance, if you are currently using 4GB RAM, you should get a larger one with 8GB RAM.

Optimize Mac

If your Mac is still running slow, you can also try to free up RAM on Mac, flush the DNS cache, run Maintenance scripts, and rebuild launch services. All these can be done with Mac Cleaner, and you don’t need to find out a detailed guide about how to do it.


Faced with a slow Mac, all you need to do is to free up more space and memory for your Mac. So you will clear cache files and junk files on Mac, uninstall unused apps on Mac, remove large and old files, delete duplicate files on Mac, and so on. To fix your Mac running slow, MacDeed Mac Cleaner will be the best Mac app that you can make your Mac faster in a quick way.
