This is where junk piles up little by little, resulting in a total mess. For a complete Mac clean up, make sure to also ditch any unnecessary widgets or apps. Wait, but you think you might need them one day? One of the reasons your Macbook Pro is running slow is insufficient free space on your hard drive. You need to periodically clean up your Mac computer from unneeded stuff and junk files to keep its speed like a brand new and 'just out of the box.' In our previous blog post, we gave seven reasons why you are losing hard drive space. CCleaner for Mac! Clean up your Mac and keep your browsing behaviour private with CCleaner, the world's favourite computer cleaning tool. Junk is often invisible, but it can take an enormous amount of space. Cleaning a Mac by yourself is a tiresome and laborious task. So, here's a tip: Try CleanMyMac for free and get temporary files, system and user cache, app leftovers, and much more removed from your Mac. It's so quick and easy, you'll be surprised.
So, your Mac is running out of storage. You try to figure out what's taking up your disk space by clicking the Apple logo on the top-left of the screen, selecting About This Mac, and hitting the Storage tab.
To your surprise, you see a yellow bar representing 'System' that seems to occupy way more space than you think it should. In the example above, it only shows 207 GB, but take a look at this Apple discussion — some Mac users report that System Storage takes an astonishing 250 GB.
Worse yet, you have no idea what's included in 'System' storage, because clicking the 'Manage' button brings you to this System Information window… and the 'System' row is greyed out.

How do I regain more storage space?
Questions like these may easily get to your head. Although my Mac now has a good amount of disk space available, I'm always wary of files that are taking up more space than they should.
I have no idea why 'System' is greyed out while 'Documents,' 'System Junk,' 'Trash,' etc. allow you to review the files based on size and type. My hunch is that Apple does this on purpose to prevent users from deleting system files that could lead to serious issues.
What Files Are Included in System Storage on Mac?
During my research, I found many people report that Apple counts iTunes backup files and app caches (e.g. Adobe video cache files) in the System category.
Since it's greyed out and we are unable to click on that category for deeper analysis, we'll have to use a third-party app to assist.
CleanMyMac X is perfect for this kind of analysis. Since I tested the app in our best Mac cleaner review, it immediately came to my head when I saw 'System' was greyed out in Storage. Note that CleanMyMac isn't freeware, but the new 'Space Lens' feature is free to use and it allows you to scan your Macintosh HD, and then show you an in-depth overview of what's taking up disk space on your Mac.
Step 1:Download CleanMyMac and install the app on your Mac. Open it, under 'Space Lens' module, first click the yellow 'Grant Access' button to allow the app to access your Mac files and then select 'Scan' to get started.
Step 2: Soon it'll show you a folder/file tree and you can hover your cursor over each block (i.e. a folder). There you can find more details. In this case, I clicked 'System' folder to continue.
Step 3: The file breakdown below indicates that some Library and iOS Support files are the culprits.
The interesting part is that the System file size shown in CleanMyMac is much smaller than the size shown in System Information. This puzzles me and makes me believe that Apple definitely has counted some other files (not real system files) in the System category.
What are they? I have no clue, honestly. But as reported by other Mac users who experienced the same issue, they said Apple also considers app caches and iTunes backup files as System files.
Out of curiosity, I ran CleanMyMac again for a quick scan. That app found 13.92 GB in iTunes Junk. Further review revealed that the junk files are old iOS device backups, software updates, broken downloads, etc.
But even after adding this amount to the original system files returned by CleanMyMac X, the total size is still a bit less than what's returned in System Information.
If cleaning the System Storage is still not enough to bring your Mac available disk space to a normal level (i.e. 20% or more), see below.
What Else Can I Do to Reclaim More Disk Space?
There are tons of ways out there. Here are a few of my favorites that should help you get back a decent amount of space quickly.
1. Sort all files by size and delete old large files.
Open Finder, go to Recents and look at the Size column. Click on it to sort all recent files by file size (from large to small). You'll have a clear overview of what items are eating up a large amount of space, e.g. From 1 GB to 10 GB, and from 100 MB to 1 GB.
On my MacBook Pro, I found a few large videos that could be transferred to an external drive.
Note: If the Size column doesn't show up, click on the Settings icon and select Arrange By > Size.
2. Remove duplicate files.
Don't forget those duplicates and similar files! They can stack up without you being aware of it. Finding them is sometimes time-consuming. That's what Gemini 2 is designed for. Simply select a few frequently used folders (e.g. Documents, Downloads, etc.) in the main zone of Gemini.
It then scans them and returns all the duplicate files that might be worth removing. Of course, it's always a good practice to review them before doing so. You can also read more from our detailed Gemini review here.
Wrapping It Up
Ever since Apple introduced the Optimized Storage feature, Mac users got the option of saving space by storing content in the cloud. Apple also has several new tools that make it easy to find and remove unneeded files.
That bar under the Storage tab is beautiful. It does allow you to get a quick overview of what's taking up the most space on our hard drive. However, it still lacks insights into the 'System' category as it's greyed out.
Hopefully, the guides above have helped you figure out the reasons you've got so much 'System' data, and most importantly you've reclaimed some disk space — especially for new MacBooks pre-installed with flash storage — every gigabyte is precious!
Just like any day-to-day item, your Mac needs a good cleaning once in a while. Getting rid of all the unnecessary files will help your Mac return to its factory excellence and speed up to match your needs. However, you might find yourself clueless as to where to start your Mac clean up: what can be deleted and what should be left on drive? Don't worry. You might be a little bit lost right now but, as usual, we have some bulletproof tips and tools to help you clean your Mac and speed it up.

If your Mac is out of storage space or starts running slow, you're up for a cleaning game. And you don't have to do it alone. We've prepared the smartest memory-boosting hacks and practices to speed of your Mac safely. Time for an easy Mac cleanup!
Clean up your Mac's Desktop
This might seem like an obvious step to take, but you'd be surprised how many Mac users believe the Desktop is the perfect place to store files and docs, handy and always on tap. However, that's a rookie mistake. Fortunately, you can fix it. That's why you should clean your Mac starting from the Desktop before you go any deeper. Be honest, can you even see your desktop background clearly now or is it obscured because of the icon-riddled mess?
The fact is, that the Finder treats any folder or file on your desktop as a window. A couple of items on the desktop cause no problem, but if the clutter persists, your Finder will soon slow down and get on your nerves. So better sort it all out to separate folders and let us quickly take you to number two.
Free up your Mac's hard drive
When it comes to storage, there are items you know about (like your photos and videos) and many hidden entities (like cache files, logs, and app junk). These deep-seated junk files may start off small, but over time they will begin to weigh your Mac down.
Tip: According to one test conducted by MacWorld, nearly full hard drives perform 17.5% slower than the cleaner ones. That's why it's so important to refresh your hard drive every now and then. Your system will convert the newly-released free space into virtual memory to ensure your apps are running smoothly. Otherwise, if you're low on space, your Mac will slow down.
How To Clean Up My Mac
One folder you should regularly clean up for a faster Mac is the Downloads folder. This is where junk piles up little by little, resulting in a total mess. For a complete Mac clean up, make sure to also ditch any unnecessary widgets or apps. Wait, but you think you might need them one day? Truth is, if you haven't used them so far, you won't use them in the future. So gather all your courage and hit Delete.
If your Mac is still running slow, then it could be due to old hardware. A new SSD or more RAM is the easiest way to boost your hardware performance without having to spend too much.
How do I know what to delete?
What's really annoying is that some massive folders on your Mac remain invisible. Each app or website visit leaves behind its own archive of data, which keeps growing over time. To hack this, you can use CleanMyMac X app by MacPaw. It uncovers large redundant files you can delete. And this application is notarized by Apple.
You can delete:
broken downloads
Juegos de mac gratis. remains of old apps
outdated cache

Download Free VersionTake control of startup and login items
When your Mac boots up, the macOS will launch various startup items. Some you do need, but nearly half of them can be safely switched off. Otherwise, they'll sit in the background using up your system resources and slowing your Mac down.
To remove startup and login items manually, go to System Preferences > Users & Groups and click on your username. Next up, click on 'Login Items' and select all the apps you don't need running at startup. Then click the '-' button below and you're done. By disabling the startup programs, you'll have a speedier Mac next time you boot up.
Repair disk permissions
Disk permissions act like doorkeepers preventing third-party apps from meddling with your system. But disk permissions can get broken, which limits your Mac ability to find the right files.
If you're on El Capitan or older OS X versions, you can repair disk permissions using the following command in the Terminal window:
sudo /usr/libexec/repair_packages --verify --standard-pkgs /
It will now check the validity of your disk permissions. If you get anything saying 'permissions differ', then you can fix it with this command:
sudo /usr/libexec/repair_packages --repair --standard-pkgs -- volume /
How Do I Clean Up My Mac
If you are a mere mortal, uneasy with using Terminal, a Mac cleaning utility like CleanMyMac X, can do a better, risk-free job. A single click in Maintenance > Repair Disk Permissions solves it without fuss. With your disk permissions fixed and verified you can enjoy a smoother overall Mac experience.
The free version of this tool is available for download here.
Once you've finished to clean up your Mac, make sure to reboot your machine for a fresh start.
Delete System Junk and browser cache
System Junk can account for significant amount of disk space. It's a broad term that describes temporary files created by your OS itself and all your apps. Since we mostly use our Macs to go online, the internet-related junk takes up the most space.
How to clean up your browser cache:
For Safari, click Develop in the top menu
Then, click Empty caches
For Chrome, click the 'hamburger' icon in the top right corner
Then click More tools > Clear browsing data
Find hidden files on your drive
You probably know that a lot of files are purposely made invisible on your Mac. Not necessarily with bad intentions. Such files could be crucial system components and thus protected from accidental deletion. Quite often, however, you'll encounter remains of old apps, invisible adware, and extensions.
There is a shortcut key combination to reveal the unseen files.
Go to your Documents, or any other directory
Click Shift +Command + Period key
Do you see any grayed out files? Check what these files are and delete them if they look suspicious.
Remove old backups (and Time Machine backups)
There are several layers of backups built in your macOS. Local Time Machine snapshots, iOS, and iCloud backups, etc. If we're talking about a clean Mac, that's free from old baggage, you should look into removing them too.
Here is how to remove local Time Machine backups (a.k.a snapshots)
Click Launchpad and type in Time Machine
Your backups will be broken by locations, like Desktop. You can use arrows to the right to navigate between past states of that location.
Now, click on the gear icon in the menu above.
Select 'Delete All Backups' in the menu.
Delete the iCloud backups stored on your Mac
Open System Preferences > iCloud.
Click Manage.. at the bottom the pane.
Look through the list of iCloud backups in the sidebar.
iCloud photos will probably occupy the most space. If you're ready to say goodbye to them, click Delete.Build the map of your storage
Any computer is ultimately a tree of folders. What if you could draw the map of all folders you have on your Mac and see how large these folders are?
Apparently, there is an ultra simple way to do it. Some applications like Daisy Disk or CleanMyMac will build such 'folder tree' for you and it's really fascinating to look at.
For example, this is the Space Lens tool from CleanMyMac X:
Download Free VersionThe blue bubbles stand represent my folders big and small. You can dive into each folder exploring your drive in a completely new way, much more informative than using the Finder. You can find your long lost folders and locate your biggest space wasters.
To use this tool, download the app (see the button above)
Click the Space Lens tab in the sidebar
