1. How to use macOS Catalina’s integrated memory optimization feature and Speed Up macOS Catalina

Step 1

From High Sierra, we’ve seen how the operating system integrates a feature designed to help us manage space on the macOS hard drive, and it’s a storage optimization feature that focuses on specific areas, such as:

  • Icloud
  • Trash
  • Total disk space
  • System Element Administration

To access this feature and see how it works in action, we need to click on the Apple logo and choose “About This Mac”:

Step 2

It will appear in the next window, where we have to click on the Storage tab. There we have to press the “Manage” button.

Step 3

In the main space optimization window, we will find segmented as follows:

Recommendation section:

This section is divided into 4 different variants and is one of the most used, as most of the storage here is centralized, where you can use the following:

  • Store in iCloud. We can use our Apple ID’s free 5GB to save items such as messages, photos, music, and more in the cloud. So they don’t stay directly on the hard drive and use more memory. But, this will need you to buy a paid plan.
  • Storage Optimization. In this section, we can customize that iTunes, TV, and others that we’ve already seen and therefore took place have been removed from the system, and with this activation, we’ll only see attached mail files.
  • The “Automatic Garbage Cleanup” section allows us to activate the automatic removal function of each object that takes 30 or more days, so of course, it happened to you and me when we forgot to remove the garbage.
  • The “Reduce clutter” section allows you to access the presentation of files in the system to see their size and determine whether they are essential for storage.

Step 4

In the main optimization item in macOS Catalina, but other sections like how we can navigate through them to see the contents of each:

Step 5

From this point of administration, we can free up space, thereby speeding up your macOS Catalina. We select files or applications that are virtually unused and pressing the “Delete” button at the bottom:

Step 6

This action will show the following warning:

This is the most used method because default macOS Catalina offers it for cleaning tasks and system improvement. This will certainly help you Speed Up macOS Catalina.

2. How to clean macOS Catalina on the hard drive to Speed Up macOS Catalina

The process of how to Speed Up macOS Catalina is to clean up files or applications not used in the system, optimize reading and writing processes, and improve internal processes. To do this, we can use two methods, the first – to delete files manually with Finder and then remove the basket.

However, many operating system files are secure, so the Finder method is not always adequate. That’s why we often have to resort to third-party apps, and it’s better than using one of the most famous apps, such as CleanMyMac, which you’ll find here:

Speed Up macOS Catalina: Using Cleanmymac app

This app is compatible with Catalina macOS, and its function is to intelligently and deep-reading the hard drive to show how space is used. It works for hidden files.

Step 1

After installing the app, we’ll see the following:

Step 2

There we go to Smart Analysis, and we can click the Analysis button to run the utility. It will require access to some files and click Grant Access.

Step 3

Once the analysis process is complete, we can access the details to check which items have been selected as debris and better control them.

Step 4

Finally, we can click “Clear” to erase these items in a few seconds and speed up macOS Catalina.

3. How to manage MacOS Catalina apps and Speed Up macOS Catalina

macOS Catalina includes a feature for detailed analysis of hardware resource consumption, such as processor, memory, drive, network, and energy, in real-time, each of which plays an essential role in the system’s performance. In general, so access to this utility and process verification will never be abandoned. This is one of the finest methods to Speed Up macOS Catalina.

Step 1

To open the activity monitor, we can use one of the following methods:

  • Using the Spotlight and searching Activity Monitor
  • Use the keys ⇧ ⌘ U, and then select the utility
  • Go/Utilities/Activity Monitor

Step 2

When the default column is shown, we’ll see the processor, where we can click on this column to sort the CPU’s resource consumption from high to low:

Step 3

The same process can be applied to other sections (memory, energy, drive, and network). Then you select the unnecessary processes that are consuming high CPU % and stop them by clicking Stop.

Step 4

It must be remembered that at the bottom of each section, we have access to a graph on which to visualize each process in specific detail.

Once you are done with this method, you will certainly experience an accelerated speed. This is an important method to Speed Up macOS Catalina.

To remove one or more apps during launch, we have to select it and click on the icon at the bottom, which will remove that app from the macOS Catalina auto-load:

6. Optimize the use of iCloud macOS Catalina

We mentioned earlier that iCloud is a bet in the Apple cloud, and it gives us 5GB for free so we can place different elements of the system, but not on the hard drive.

Step 1

To customize this option, go to System Settings and see the following in macOS Catalina:

Step 2

Click on the Entry button and then enter Apple ID and the corresponding password. Now browse to iCloud section.

Step 3

Edit items to load into the cloud as needed:

7. Reset SMC and PRAM / NVRAM in MacOS Catalina

SMC RAM and memory are combined to improve system performance, so if we reset SMC memory, we help fix various battery and fan problems. By resetting the NVRAM module, we’ll help you set up the boot drive, screen resolution, and battery life to optimize better and experienced improvements and Speed Up macOS Catalina.


If we want to reset the NVRAM, we’ll need to restart the operating system and press the Command and R-Option keys in the process. When we release the keys, we’ll free that memory.

P + P + R + ⌥

Reset SMC

On the contrary, if we want to reset the SMC, we must first turn off the hardware and leave it off for 15-20 seconds, then press the Shift button q Command q Option q Power for 10 seconds.

⇧ + ⌘ + ⌥ + ON

Spotlight Management

Spotlight is an automatic macOS Catalina search system, which uses indexing technology to get the best results. Therefore, if Spotlight is configured to index all pieces of hardware, it will take longer than usual to re-identify, which will affect normal resource usage and hurt system performance.

To make sure of this, we go to System Settings and click on the Spotlight category, and in the window, we move to the Privacy tab.

You can now select folders that you don’t want to add to the macOS Catalina indexing process, which helps improve the system’s response time.
