3. Manage Startup and Background Processes

Apps that run at startup consume CPU and memory, slowing down boot times. Turning off unnecessary background applications can speed up your Mac.

How to disable startup apps:

Go to System Settings > General > Login Items.
Review the apps listed and remove unnecessary ones by clicking the “-” button.

4. Clear System Junk and Cache Files

Temporary files, cache data, and system junk accumulate over time, reducing available storage and slowing down performance.

How to manually clear junk files:

Open System Settings > General > Storage.
Review recommendations and delete unnecessary files.
Remove unused apps, old downloads, and log files.

Open System Settings > Battery.
Enable Low Power Mode to reduce power consumption during high workloads.

Lower display brightness for better power efficiency.
Enable Optimize Video Streaming while on Battery.

6. Keep Your Mac Cool

Overheating can throttle CPU performance, causing your Mac to slow down. Keeping your Mac cool prevents system slowdowns and enhances efficiency.

Cooling tips:

Use your Mac on a hard, flat surface to improve airflow.
Avoid blocking air vents, especially when performing intensive tasks.
Consider using a cooling pad for additional airflow.

7. Quit Unused Applications

Leaving apps open in the background consumes system resources and reduces performance.

How to close apps efficiently:

8. Disable FileVault Encryption (If Not Needed)

FileVault encrypts your disk, improving security, but it can also slow down older Macs. If you don’t need full-disk encryption, disabling FileVault may improve performance.

To disable FileVault:

Open System Settings > Privacy & Security.
Scroll to FileVault and click Turn Off.

Only disable FileVault if you are comfortable with reduced encryption security.

Use Stacks (Right-click on the desktop > Use Stacks) to organize files automatically.

Reducing the number of desktop icons speeds up system responsiveness.

10. Run Regular System Maintenance

Routine maintenance prevents system slowdowns and keeps macOS Sequoia running smoothly.

Essential maintenance tasks:

Reindex Spotlight to improve search performance.

You can rebuild the Spotlight index using the Terminal command:
sudo mdutil -i on /

Flush DNS cache for better internet connectivity.

Type using the Terminal command:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

Clear system logs to free up storage.

To clear system logs on your Mac, navigate to the /Library/Logs folder using Finder, select the log files you want to remove, and move them to the Trash. Emptying the Trash will permanently delete the logs, and macOS will automatically recreate any necessary log files.

Reset network settings to fix connectivity issues.

To reset network settings on your Mac, go to System Settings > Network, select Wi-Fi, click Advanced, remove all saved Wi-Fi networks, and then click Done.

Repair disk permissions using Disk Utility.

To repair your permissions using the Disk Utility:

Choose Go > Utilities.
Double-click Disk Utility.
Select the volume in the left pane for which you want to repair permissions.
Click the First Aid tab.
Select the volume to which you want to install the Adobe application, and then click Repair Disk Permissions.

Performing these tasks bi-weekly enhances overall system performance.

11. Close Unused Browser Tabs

Web browsers consume a significant amount of RAM, especially with multiple tabs open. Managing tabs efficiently can improve speed.

Best practices for managing browser tabs:

Close tabs you no longer need.
Use tab suspender extensions to pause inactive tabs.
Bookmark frequently visited websites instead of keeping them open.
