1. Click on the Apple Menu and select About This Mac.
2. Go to the Storage tab and click Manage.

Here, you’ll find several options to free up space:

• Store in iCloud: Move files and photos to iCloud to free up local disk space. Only recently used files remain on your Mac, while older files are stored in the cloud.
• Optimize Storage: Automatically removes downloaded iTunes movies and TV shows that you’ve already watched.
• Empty Trash Automatically: Automatically deletes items from the Trash after 30 days.

These features make it easy to manage storage without manually sifting through files.

b) Delete Large and Unnecessary Files

For a more manual approach, identify and delete large files that you no longer need:

1. Open Finder and click All My Files or use the search bar in Finder to filter files by size.
2. Sort files by size and review the largest files on your Mac. You can then delete, move to an external hard drive, or upload them to iCloud.

For more control over large files, third-party apps like DaisyDisk or CleanMyMac X can provide a visual map of your storage and help you safely remove large or redundant files.

c) Clean Up System Junk

Over time, your Mac accumulates system junk such as cache files, logs, and temporary files that are no longer needed. You can manually clean these up or use specialized software to streamline the process.

• CleanMyMac X is a popular app that scans your system for outdated cache files, old log files, broken app data, and more. It allows you to remove these files with a single click.
• You can also manually clean your Mac’s cache by navigating to ~/Library/Caches in Finder, but be cautious not to delete important system or application files.

d) Manage and Clear Downloads

Many people forget that their Downloads folder can become a significant source of clutter. Files downloaded from the internet, such as installers, documents, and media files, can quickly pile up and take up space.

1. Open Finder and click Downloads.
2. Sort the folder by date or size and delete any files that you no longer need. Consider moving important files to more organized folders for long-term storage.

3. Improving System Performance Through App Management

Applications, particularly those running in the background, can consume a significant amount of your Mac’s resources, causing it to slow down. Optimizing how you manage and use applications can improve overall performance.

a) Close Unused Applications

Even if you’re not using an app, it may still be running in the background and consuming RAM and CPU resources. To check which apps are active:

1. Use the Activity Monitor, found in Applications > Utilities.
2. In Activity Monitor, you can see all running applications and their CPU and memory usage. Close unnecessary apps by selecting them and clicking the X button at the top of the window.

Alternatively, you can use the keyboard shortcut Cmd + Q to close an app or Cmd + W to close individual app windows without quitting the app completely.

b) Use Lighter Alternatives to Resource-Intensive Apps

Some apps, especially creative software like Photoshop, video editors, and even web browsers with many tabs open, can hog resources. Consider lighter alternatives for routine tasks:

• Use Preview for basic image edits instead of a full-fledged image editor.
• Opt for lightweight browsers like Safari (which is optimized for macOS) instead of more resource-hungry options like Chrome.

Choosing lighter apps for less intensive tasks can free up valuable system resources, improving overall performance.

c) Uninstall Unused Applications

Many people have applications installed on their Mac that they rarely or never use. These apps take up disk space and may run background processes that slow down your system. To uninstall apps:

1. Open Finder and go to Applications.
2. Drag the app you no longer need to the Trash, or right-click and choose Move to Trash.

For a more thorough uninstallation that removes all associated files, you can use an app like AppCleaner, which finds and deletes any leftover files from uninstalled applications.

d) Disable Resource-Heavy Browser Extensions

If your web browsing experience feels sluggish, your browser extensions might be the culprit. Too many extensions can slow down browsing, consume memory, and even affect overall Mac performance.

To manage browser extensions in Safari:

1. Open Safari, then go to Safari > Settings (or Preferences) and click on the Extensions tab.
2. Disable or remove any extensions you no longer use.

For Chrome or Firefox, you can manage extensions by going to the browser’s settings and navigating to the Extensions section.
