13 Ways to Speed Up macOS Catalina on Mac
Fix 1: Close System Consuming Process: Keep Eye on it
Mac is full of assets, few are useful and some are just eating the power and slowing down the Mac for no reason. However, there is a way through which you can find the resource-hungry process and shut them down to speed up Catalina. Open the Application folder > Utilities > Activity Monitor or directly make a spotlight search for Activity Monitor.
The Activity Monitor is mainly divided into CPU, Memory, Disk, Energy, and Network. But our primary goal is to speed up macOS Catalina or any Mac, so click on the CPU tab. The CPU tab will show, which processes or software is eating most of the memory. There also multiple factors are used to show memory usage by applications, so check under % CPU, which app is consuming processor of Mac.
Click on the process to select and close it by clicking on X which is on the upper-left side of the screen.
Fix 2: Remove Startup Programs
Startup programs are responsible for the slow performance of Mac, right when you press the Power button to boot the system. And if the system starts slowly, it will definitely take time to launch applications like Chrome, Safari or anything. How to speed up MacBook after macOS Catalina Update? The answer is, remove startup programs- once you do so, the Mac will start fast and eventually, other applications would perform better.
- System Preferences > Users & Groups > Select User > Login Items
Now select the programs that you don’t need during startup and click (-).

- Also, replace the Genie effect with Scale effect.
Now, all the unhelpful visual effects will not appear on your Mac.
Fix 4: Delete Browser Extensions
Before removing extra extensions from different browsers, I would like to suggest you delete the browser if it is unused. There are people who keep Google Chrome, Firefox and they have Safari by default. Therefore, if you are not using any one of them, delete the third-party browsers to speed up Mac. In addition, do you know how many extensions are installed on your Mac’s browser? These add-ons continuously grab a bigger part of MacBook’s processor and slow down. If you feel any of the extension is useless, then remove it from the browser.

Step #1: Go to “System Preferences”.
Step #2: Click “Spotlight”.
Step #3: Select the “Privacy” tab.
Step #4: Drag/Put the Hard Drive into the Privacy tab from Finder.

Fix 6: Manage Desktop Applications
Reducing desktop cluttering could really boost up Mac’s performance and speed up macOS. And so with macOS 10.15 Catalina update, Apple has introduced a new feature called Desktop Stacks to manage the desktop applications, folders, and files. Or if you don’t have macOS Catalina, then merely delete the applications/files or move them to other location.
Fix 7: Clear Cache on Mac
I assumed you are aware of the word Cache. Cache is usually meant to speed up the processes, but if the cache files exceed then it gradually decreases the performance of the system. There are three types of cache, System Cache, Browser Cache, and User Cache. We do not recommend to delete App Cache as it may corrupt the application.
How to Clear User Cache on Mac
Step #1: Launch “Finder”.
Step #2: Click on “Go” and choose “Go to Folder”.
Step #3: Enter the path, ~/Library/Caches and proceed.

Once you have empty all the folders, type the /Library/Caches path by following the same above steps and clean these folders too.
Make sure to Empty Trash after clearing the cache files.
How to Clear Browser Cache on Mac
Browser cache could really free up junk files. Most of the junk files are stored in the Browser as all the time we are lurking on the browser. But clearing browser cache has one downside, it will also remove history and other information for privacy factor.
- Launch Safari > Preferences > Advanced tab > Check the Show Develop menu in menu bar > Go to Develop Menu > Empty Caches.
- Menu > Settings > Advanced > Clear Browsing Data.
- Delete the data as per your convenience and click Clear Data.
- Menu > Privacy & Security > Cached web content > Clear Now.

Though just dragging and dropping the application to Trash isn’t enough to free up space on Mac. Here’s the complete guide to delete the app in macOS.
Free Up RAM
RAM plays a very important role in the performance of the macOS or any device. Once you free up RAM using Terminal app on Mac, it may be restored with the same speed. So when any particular app starts to freeze or gets stuck in between then you should clean up RAM.
