Like other computers, Macs are also prone to slowdowns, meaning that they become sluggish over time. Working on a slow device can be quite annoying. More than a hundred reasons are responsible for your computer’s poor performance. However, frequent system optimization is the solution to improve your system’s productivity, whether it’s a Windows or a macOS device. 

In this article, we will discuss some of the common tips to use MacBook computers and improve their performance. But first, let’s take a look at some of the reasons that make your Mac slow. 

What Causes Mac Slow Downs?

Background processes drain memory

macOS does not actively inform you when the background apps and programs consume a considerable CPU and other resources. Some of these processes may become corrupt or infected and start behaving strangely, making your system slow. 

High-Resolution visuals & graphics

You might have noticed that your MacBook’s system performs poorly when you try to run a graphics-heavy task, which is perfectly fine. But if your Mac is not allowing you to do a simple job or running a lighter app, you might need to adjust the visual effects. 

Outdated apps or programs

This is probably the most common reason behind the slow-performing computer. When applications and programs become outdated, they start performing differently, which is sometimes annoying. Deleting these apps might help resurrect the system resources. 

So, tweaking the software applications and hardware components can help improve the Mac functionality. However, there are some sure-shot ways that can help you boost your computer’s overall health. 

Ideas to Improve macOS Performance


Clean up redundant files & documents

The cleaner your system is, the better it will perform. File clutter starts accumulating on your system taking up disk space and resulting in unresponsive applications, sudden shutdowns, excess heating, and more. 

Removing redundant data, junk files, temporary system files, or duplicate files can help alleviate MacBook performance issues. To delete a file, select the item and hold down Command + Delete keys or simply drag the item and drop it to the bin in the Dock. 

If you delete your files using either of these ways, do not forget to empty the Trash bin. To remove deleted items permanently from the Trash bin, click the Trash icon in the Dock and click the Empty button available in the upper-right section of the Finder window. 

Move data to iCloud or an external HDD

One major reason behind Mac slow down can be tons of volumes of data which is consuming a lot of space on the hard drive. If you are storing important files on your computer which you cannot delete, moving them to external storage media is a great way to make space to speed up your MacBook.

When we store huge amounts of data on our system, the performance starts to degrade as the files consume a considerable amount of system resources. You can also think about moving your data to an iCloud drive to free up your computer hard drive. 

The major benefit of storing data to the iCloud drive is that you can access this data on any Apple device right from anywhere. Moreover, iCloud offers 5GB of free space on signup, so you will not require to spend hugely on buying the storage space. 

Disable login items 

Whether you are using Windows PC, MacBook, Android phone, or the latest iPhone, there are apps that start automatically each time you switch on your device. These applications are called login items that get activated when you log in to your system, regardless of the operating system you use. 

To deactivate login items, click the Apple menu, go to System Preferences, and then click Users & Groups. Click on your profile name and tap the Login Items option. Highlight the apps and programs that you want to disable, and click on the – sign. Next, click the Apple menu and select Restart.

If your system starts working, you can add the required login items one at a time. If this workaround doesn’t seem to provide a solution to your problem, you can try alternate resolutions to speed up your Mac. 

Detect & delete resource-heavy apps

When your professional tasks demand working with resource-heavy apps such as graphic design applications or gaming platforms, you might experience slow system performance. If so, you will have to pick the apps that are consuming lots of storage and need to kill them. 

But how can you detect which application is consuming how much storage? Well, you can use Activity Monitor to check the current resource consumption by each individual app. Go to the Activity Monitor and click Memory to check details on Memory Pressure, Physical Memory, Memory Used, Cached Files, Swap Used, etc. 

The Memory Pressure option under the Memory pane can help you detect how much RAM your system is using. The graphical representation (green, red, and yellow) explains whether your system is utilizing the memory resources efficiently or it needs more RAM.
