Running out of storage is a common problem for many Mac users, especially if your device is a bit older. In this post, I’ll share the simple steps I use to check storage and free up space to keep my Mac running smoothly. Let’s dive in!

Before We Begin

Besides unnecessary data and unused applications, duplicate files can also eat up valuable storage on your Mac. Using MacKeeper, you can effortlessly locate and remove these redundant files. MacKeeper even identifies photos that may look similar but aren’t exact duplicates, allowing you to free up more space with ease.

How to Manage Storage Space on Mac with MacKeeper

1. Uninstall Unnecessary Applications

    Uninstalling unnecessary applications is an effective way to free up valuable storage space on your Mac. Over time, you may accumulate apps you no longer use or need. Removing these can not only declutter your system but also improve its overall performance.

    You can use MacKeeper to uninstall unwanted apps on your Mac. Here’s how:

    1. Download and install MacKeeper on your Mac.
    2. After installation, launch MacKeeper and click the Smart Uninstaller in the left-hand menu.

    2. Clear Cache and Temporary Files

    Cache and temporary files are often generated by apps and browsers to speed up tasks but can accumulate over time, unnecessarily hogging disk space. Regularly removing them can maintain your system’s health and efficiency.

    MacKeeper offers an easier way to remove cache and junk files from your Mac. You don’t have to find the files manually, preventing accidental deletion of important files. Here’s how to use MacKeeper to clear cache on your Mac:

    1. Download and install MacKeeper on your Mac.

    3. Manage Startup Items

    Startup items are applications, services, or tasks that automatically launch when you boot up your Mac. While some of these are essential for system performance, others can drain your system resources, leading to a slower startup time.

    An easy way to remove login items on your Mac is using MacKeeper. Follow these steps to get rid of unnecessary login items on your Mac:

    1. Download MacKeeper and install it on your Mac.
    2. Open Login Items under Performance in MacKeeper.

    4. Find and Delete Duplicate Files

    Duplicate files are sneaky storage hogs that can accumulate over time. These could be multiple copies of the same photo, document, or even applications. Not only do they consume valuable disk space, but they can also make your file system messy and confusing.

    You can use MacKeeper’s Duplicates Finder to find and delete duplicates on your Mac. Follow these steps to delete duplicates on your Mac using MacKeeper:

    1. Download and install MacKeeper on your Mac.
    2. Open MacKeeper on your Mac and click Duplicates Finder in the left sidebar.

    Check Mac’s Used and Available Space

    Now that you know how to check and manage storage space on your Mac, you may want to learn more about making the most of your system resources. Here are a few tips to get you started:

    Frequently Asked Questions

    What is taking up so much space on my Mac?

    Various files and applications can take up space on your Mac. Common culprits include system files, apps, documents, media files like photos and videos, and temporary files such as cache and logs. You can check what’s taking up space by going to About This Mac and then the Storage tab.

    How much space should the system take up on Mac?

    The system storage on a Mac can vary depending on the macOS version and installed updates, but it generally occupies around 8-15GB. If you notice system storage taking up significantly more space, it might include temporary files, caches, or system backups that could be safely cleaned to free up space.

    What should I delete from my Mac?

    To free up space on your Mac, consider deleting unused apps, old documents, duplicate files, and temporary files like cache and logs. Emptying the Bin can also reclaim storage. Always be cautious when removing system files; consult expert advice or use trusted software to assist with the cleanup.

    How much free space should I have on my Mac hard drive?

    It’s generally recommended to keep at least 10-15% of your Mac’s hard drive free for optimal performance. Lack of free space can slow down system processes and hinder software updates. You can check your available storage by going to About This Mac > More Info > Storage tab.

    What do I do when my Mac storage is full?

    When your Mac storage is full, start by emptying the Bin and deleting unnecessary files like old documents and unused apps. You can also clear cache and temporary files. Consider using built-in macOS tools to optimize space, or move files to external drives or cloud storage.
