How to Clean Up Your Mac: 12 Quick and Easy Methods

Is your Mac not running as smoothly as it used to? You might be wondering if it’s time for a cleanup.

What you'll be reading

If your computer crashes when you’re using multiple apps, runs slower than usual, or shows “out of storage” alerts, it’s probably time to give your Mac some attention.

Don’t worry – keeping your Mac in top shape is easier than you might think. Let’s explore some simple ways to clean up your Mac and get it running like new again.

What Takes Up Space on Your Mac?

Have you ever wondered what’s filling up your Mac’s storage? Let’s take a look at the main space-hoggers, starting with the biggest culprits:

Large and old files often take up more space than you might think. These could be movies, big software installers, or old documents you’ve forgotten about.
System junk includes unnecessary files that your Mac keeps around, even though you don’t need them anymore.
App leftovers are bits and pieces of programs you’ve deleted that didn’t fully clean up after themselves.
Old backups can eat up a lot of space. These are copies of your data that you probably don’t need anymore.
Photo clutter like duplicate or similar images can add up quickly if you take a lot of pictures.
Your Trash bin might be holding onto files you thought you’d gotten rid of.
Finally, mail attachments can take up space without you realizing it.

How to Clean and Optimize Your Mac?

If you’ve never cleaned up your system before, your Mac has probably gathered a lot of unnecessary stuff over time. Let’s go through some simple steps to tidy up, starting with the most effective ones. For the best results, try to follow all these steps!

1. Update Your Software

Cleaning is just the start – keeping your software up-to-date is key for a smooth-running Mac. Here’s how to do it:

For your Mac:

The more apps you have, the slower your Mac might run. It’s important to get rid of apps you’re not using anymore. Here’s how:

Right-click on the app
Choose Move to Bin

But be careful! Just moving an app to the Trash doesn’t fully remove it. To completely clean up:

3. Get Rid of Large and Old Files

Keeping your hard drive clean isn’t just about being tidy – it’s necessary for your Mac to run well. Finding and removing large files can make a big difference.

Try to keep at least 15-20% of your hard drive free. Tests show that having more free space can make your Mac up to 35% faster, which is great if you work with big files like videos or graphics!

4. Empty Your Trash

Deleted files aren’t really gone until you empty the Trash. They’re just sitting there, taking up space. Here’s how to truly get rid of them:

Click and hold the Trash icon in the Dock
Choose Empty Bin

This will help free up space and might make your Mac faster.
