A fully loaded startup disk is something that will take place from time to time if you are a Mac user. In this case, you will notice a message about the error. After deleting some data from your computer, your hard drive will have some free space. However, the ways of resolving this issue are not limited. Simple cleaning of a Mac hard drive can be done in any other similar way. In this article, I will discuss the top methods how to clean a mac hard drive and get some free disc space.
During the working process, a hard drive, in any case, does not have to get beyond its 80% capacity. If you get some notifications about the full startup disk, you need to conduct some activities not to get delays and unsatisfactory work of a Mac. Otherwise, you will experience slowness and errors. Having this in mind, you need to clean up the Mac hard drive to bring it some free space without probable errors generated by the full disk.
Notably, you can also use an application like MacFly Pro. This app will help you get as much free space as possible and get rid of irrelevant stuff like corrupted cache or any duplicate files. It can boost up the quality of your Mac and save you hours of manual cleaning.
Steps to Take if You Have No Free Space on Your Mac
Step 1: Decide What To Delete.
So you have no free disk space on Mac? Fl studio 11 download mac. To clear some space, you need to:
Mac Hard Drive Cleaning Software
- Search and analyze what files and sections take all of your disk space;
- Then just remove the applications, files, or folders from your Mac manually or with the help of applications;
- Otherwise, you can move them to the cloud system or an external hard drive.
Thus, be sure that you have a general understanding of what you are going to delete.
To know more about it, you just click the Apple menu > About This Mac. After this, just select the “Storage” tab and check the capacity of the disk storage in it.
Step 2: Delete the Files
In general, the large amounts and size of files cause the problem of insufficient space. To solve the problem and delete the files from Mac, it is possible to:
1. Clean the trash can
You can make it by clicking Ctrl+Click as well as right-click the Trash icon on your desktop. Just select Empty Trash and click the section. This action will delete the files sent to the trash.
In particular, all Macs can have a lot of trash cans. Therefore, a user might need to empty all of them. Thus, if you use iPhoto and want to delete some data from this section, just clean the trash in iPhoto. After that, you need to delete them from your hard drive. To make it, you have to right-click the Trash (or Ctrl+Click) in the chosen application and click Empty Trash.
2. Delete old iOS backups in iTunes
The method can be used for old devices that were backed up a long time ago but no longer belong to you. In this case, a user may choose iTunes > Preferences > Devices > Select the version of backup to remove > Delete Backup.
3. Remove all the app caches and uninstall old Mac applications
It is natural that not all of the Mac apps are the best ones indeed. A user can just move these files to the Trash can as well. One needs to click the icon named Launchpad within the Dock. After that, just press on an icon with the left button of a mouse. Whet the selected icon starts to jiggle you can delete the needed app.
4. Clear temporary files
Your Mac does contain temporary files in any case. During the work with Macs, there are a lot of files that are left after some processes. They can be cookies of your Internet history, any browsers caches, and so on and so forth. For example, you can clear Safari caches to get more space. You just have to click Safari on your screen and click Preferences in the menu. Take these steps after:
- Select the Privacy tab and choose Remove All Website Data;
- Select Remove Now in the popped-up window.
Step 3. Move files to the iCloud storage or another hard drive
All the files can also be moved to the additional external hard drive or iCloud storage as well.
Moving Your Files to an External Hard Drive:
- Any connected hard drive or USB device will appear within the Devices menu.
- Select those files that you need to transfer and press the “Command” button.
- The next step is to drag and drop the files from the window of Mac’s Finder into the window of an external hard drive.
- Eventually, click the button named “Eject” and remove your hard drive when you finish.
Now you know how to remove all the unnecessary data manually, however, I would recommend you using a MacFly Pro to get more free space and save a vast amount of free hours for something really valuable.

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 33.87 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.

What does it contain?
Is it safe to remove some of those system files?
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. https://renewalways576.weebly.com/open-dmg-files-on-pc.html.
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 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 DaisyDisk, 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.
In 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. Run CleanMyMac.
If you are not a power Mac user, another way to help you quickly locate unnecessary files is using CleanMyMac, an app that won our award for the best Mac cleaner software. As you can also see in my detailed review here, I believe CleanMyMac is a must-have app for all basic users.

3. Remove duplicate files with Gemini 2.
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 our Gemini review here.
Wrapping It Up
Ever since Apple introduced the Optimized Storage feature on macOS Sierra and High Sierra, 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 on 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 (usually 128 GB or 256 GB) — the storage is so precious!
