Additionally, increasing the RAM (memory) capacity can improve multitasking capabilities and overall system performance.

3. Manage Startup Items

When your Mac starts up, it loads various applications and processes, some of which may not be necessary or used frequently. Navigate to System Preferences > Users & Groups > Login Items and review the list of startup applications. Remove unnecessary items by selecting them and clicking the “-” button. This will reduce the burden on your Mac during startup and accelerate its boot time.

4. Disable Visual Effects

macOS comes with several visual effects that, while aesthetically pleasing, can consume system resources. Disabling or minimizing these effects can enhance the speed and responsiveness of your Mac. Open System Preferences > Dock and uncheck “Animate opening applications” and “Automatically hide and show the Dock.” Similarly, in System Preferences > Accessibility > Display, reduce motion by selecting “Reduce motion” and disable “Transparency.”

5. Optimize Energy Settings

Adjusting your Mac’s energy settings can also contribute to its overall speed. Open System Preferences > Energy Saver and ensure that the “Put hard disks to sleep when possible” option is selected. Additionally, lower the display sleep time to conserve energy and prevent unnecessary strain on system resources.

6. Update macOS and Applications

Keeping your operating system and applications up to date is crucial for optimal performance. Regularly check for software updates in the App Store and install the latest versions of macOS and your installed apps. Developers often release updates to improve performance, fix bugs, and enhance compatibility with newer technologies.

7. Use Lightweight Applications

Replace resource-intensive applications with lightweight alternatives whenever possible. Look for apps that have lower system requirements or specialized versions designed for older hardware. For instance, consider using lightweight web browsers like Safari or Firefox instead of memory-hungry alternatives.

8. Disable unnecessary startup services

Some applications and services may launch automatically when your Mac starts up, consuming valuable system resources. To disable unnecessary startup services, go to System Preferences > Users & Groups > Login Items and uncheck the applications that you don’t need to start automatically. This will reduce the burden on your system during startup and improve its performance.

9. Clear browser cache and extensions

Web browsers often accumulate a significant amount of cache, cookies, and extensions over time, which can slow down browsing speed. Clear the cache regularly and remove unused or unnecessary browser extensions. Additionally, consider using an ad blocker or a lightweight browser extension to further optimize your browsing experience.

10. Reset SMC and NVRAM

The System Management Controller (SMC) and Non-Volatile Random-Access Memory (NVRAM) store various settings related to hardware and system configuration. Resetting these can help resolve performance issues. To reset the SMC, shut down your Mac, press and hold the power button for 10 seconds, then release and start your Mac. To reset the NVRAM, shut down your Mac, press the power button, and immediately hold down Command + Option + P + R until you hear the startup sound for the second time.

11. Limit the number of open applications

Running multiple applications simultaneously can strain your Mac’s resources, especially if it has limited RAM. Try to limit the number of open applications and close any unnecessary ones. If you frequently use resource-intensive applications, consider closing or quitting other apps to free up more system resources for the ones you need.

12. Use a lightweight antivirus

While it’s important to have antivirus software installed, some security suites can be resource-intensive and slow down your Mac. Opt for lightweight antivirus solutions that offer effective protection without heavily impacting system performance. Perform regular scans to ensure your Mac is protected from malware and viruses.

13. Disable automatic iCloud syncing

If you have enabled automatic iCloud syncing for various apps and services, it can consume system resources and impact performance. Open System Preferences > Apple ID > iCloud and review the list of apps and services that are set to sync automatically. Disable syncing for any unnecessary items or those that you can manually sync when needed.

14. Consider a clean installation

If your Mac is still running slow despite these optimizations, consider performing a clean installation of macOS. Back up your important files and perform a fresh installation of the operating system. This will remove any accumulated system clutter and give your Mac a clean slate, potentially improving its speed and performance.

15. Enable “Optimize Storage”

macOS includes a feature called “Optimize Storage” that helps manage storage space efficiently. Go to Apple menu > About This Mac > Storage > Manage. Enable “Optimize Storage” to let your Mac automatically remove unnecessary files, such as local copies of iCloud Drive files, app installers, and email attachments. This can free up valuable disk space and improve overall system performance.

16. Use Activity Monitor

Activity Monitor is a built-in utility that allows you to monitor and manage system resources. Open Activity Monitor from the Utilities folder within the Applications folder, or use Spotlight to search for it. Identify resource-hungry processes or applications that consume a significant amount of CPU or memory. Consider closing or quitting these applications to free up system resources and speed up your Mac.

17. Create a new user account

Sometimes, performance issues on a Mac can be attributed to a user account with corrupted settings or configurations. Creating a new user account can help isolate and resolve such issues. Create a new user account in System Preferences > Users & Groups. Log in to the new account and observe if the performance improves. If it does, you can migrate your files and settings to the new account or continue using it.

18. Reduce desktop clutter

Having a cluttered desktop with numerous files, folders, and shortcuts can slow down your Mac’s performance. macOS treats each desktop icon as a separate window, consuming system resources. Clean up your desktop by organizing files into folders or moving them to a different location. Alternatively, use the “Stacks” feature in macOS to automatically organize files on the desktop neatly.

19. Disable unnecessary visual effects in Dock

The Dock in macOS includes several visual effects, such as magnification and animations, which can impact performance. To disable these effects, go to System Preferences > Dock. Uncheck the options like “Magnification” and “Animate opening applications.” Disabling these effects can make your Mac feel more responsive, particularly when interacting with the Dock.
