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.

Why does my Mac system require so much space?

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.

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.

Apple may provide or recommend responses as a possible solution based on the information provided; every potential issue may involve several factors not detailed in the conversations captured in an electronic forum and Apple can therefore provide no guarantee as to the efficacy of any proposed solutions on the community forums.

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!

Is your Mac machine running a bit slowly? Does it hang up more often? MacBook, iMac, it doesn’t matter. Over time, the main drive of your machine accumulates all kinds of files that can slow down macOS, especially latest macOS version requires more disk storage and higher RAM (memory).

Reasons behind a slow Mac vary, so are solutions to tune it up. Just do a quick search in Apple Support Community, you’ll find tons of optimization tips — though many aren’t really that helpful.

In general, there are two ways to speed up a Mac:

1. Upgrade hardware;
2. Optimize macOS system.

If your Mac machine is struggling to meet the basic requirements for a newer macOS, you’ll benefit from the addition of RAM or solid-state drive (SSD).

If the slowdown is software or mac system related, a Mac optimizer app can help most of the time. Although we’d be realistic that it is unlikely that you’ll tune up your Mac with rocket speed.

In this review, we’ll show you the best Mac optimizer apps that can help clean, tune-up, and improve your Mac’s performance. Depending on the conditions of your computer e.g. new or old, storage space enough to not, your mileage may vary.

Quick Summary

Want to save time exploring? We understand. Here’s a recap of our recommendations:

• If your Mac is slow because the startup disk is almost full, get CleanMyMac to run a quick scan and remove those system junk and unnecessary files.
• For most Mac users especially those who aren’t tech-savvy, you’ll love what IObit MacBooster has to offers. It’s a one-stop Mac maintenance tool that can protect and tune up your Mac.
• If you just switched to Mac from a PC and prefer apps that are easy to use, CCleaner Pro is also a great option and it’s available for both macOS and Windows. You may also consider Stellar SpeedUp Mac as it all starts with one-click to scan and fix all found Mac issues.

Best Mac Optimization Software: What to Consider?

There is a wide range of Mac apps that claim to be able to speed up or make a Mac run faster, and usually, each of them has its own unique features. It’s really challenging to put them in comparison, so we review each Mac cleaner / speed app based on the following factors.

Security

The app should be free of malware or bundled apps. Although macOS is less prone to be infected with viruses or malware compared to Windows OS, it’s still worth paying attention to as this breaking news reported by WIRED:

Mac harddrive cleaner. “…while Apple has earned a strong reputation for security, a string of significant vulnerabilities in macOS and iOS have strained Apple’s safety net.”

Therefore, many people say macOS isn’t safe anymore (in our opinion, we’d add “that” before “safe”). We test this by running Mac security software to test whether the app contains malicious procedures. To be honest, we knocked out quite a few programs such as MacKeeper, which was reported by many Mac users for being hard to uninstall. Offensive software like that also hurt user experience.

App Quality

The app must deliver what it claims to offer, simple and fair! In our opinion, if a piece of software or app turns out to be different from what it claims to be — for example, fails to free up a decent amount of disk space, or improve the performance of our Macs (which show a bit age), then the value of getting such an app becomes little if not none at all.

Also, we prefer Mac apps that are light-weighted. That means even if a Mac tuneup app does a great job in helping reclaim tons of storage by clearing system junks, but at the cost of consuming a big portion of system resources while running in the background, we’d rather not to feature it in our best list.

macOS Compatibility

This is very straightforward. Apple pushes out a main yet new version of macOS once a year and to date, it’s High Sierra 10.13.3. If an app is unable to run smoothly under High Sierra, it’s definitely a problem. Because most Mac users will upgrade to the latest macOS sooner or later. According to ComputerWorld, 25% of all Mac users upgraded to 10.11 El Capitan in the first month, not to mention those who chose to upgrade on and from day 31.

If the developer of a Mac app fails to update the software in time, chances are the app has compatibility issues with the latest macOS version. Those who download and install it would have a hard time running it smoothly, let alone fixing potential Mac issues and optimizing your Mac’s performance.

Tech Support

Not all Mac users are tech-savvy. Those who just joined the Apple Mac family or switched from the PCs will take much time getting familiarized with Apple’s macOS operating system. When it comes to handling technical tasks such as diagnosing Mac system issues, removing junks, cleaning caches, uninstalling third-party apps, etc., novice users definitely need help along the way so it’s ideal that the app developer can offer prompt tech support.

For example, we value developers that provide various channels for customers (and potential customers) to reach out to, those could include emails, online chat, social media, or even phone calls. We have therefore decided not to include several programs written by individual developers who are unable to provide a decent level of support.

Ease of Use

All software programs are designed for human beings, not machines. It’s important that the best Mac performance tuneup software should be fairly easy and simple to use. From user interfaces, interactive buttons, to explanatory text instructions, they must be clear and to the point.

Speaking of this, one main reason why our AnySoftwareTools team love Macs more than PCs is that macOS is much friendlier than Windows. We all are used to the awesome feeling of smooth navigation on our MacBooks, right? If a third-party Mac optimization software can’t live up to this principle, we’ll hesitate to recommend it unless it shows merits over other aspects.

Pricing

Well, pricing used to be the primary factor when we make decisions and it’s reasonable. Who wants to pay for commercial software given that a free option is available in the market. However, the truth is these days freeware or open-source are becoming rare. Plus, many times free apps just don’t cut it.

What do we mean? Well, we’ve tested a number of free Mac cleaner and optimizer apps, only to find that some aren’t compatible with High Sierra due to lack of update, while others are either confusing to use or very limited in terms of features. We’d rather not to say this, but it’s often tedious and frustrating to install a free app and remove it later on.

Best Mac Tune-up Software in 2019: Our Picks

All the apps recommended below are safe to download and use (in other words, they are free of virus or malware). They are also moderately easy to use with sleek interfaces and clear instructions. And we tested them on a High Sierra based MacBook Pro and they all turned out to be fully compatible with the latest macOS. Also, we chose them because they have a dedicated support team taking customer queries.

1. Best Mac Cleaner: CleanMyMac X

Best Mac Computer Cleaner

Most newer Mac machines (especially MacBooks) are now with small-volume flash storage starting from 256GB, that means your Mac will fill up quickly and run slowly after some time. What can you do? The answer seems oddly simple: clean up Mac drive. But the process isn’t as easy as it may sound. Often it takes hours if not days to find out what files taking up the major disk space.

That’s where CleanMyMac excels. It’s an intelligent app designed and developed by MacPaw, aiming to make your life easier. You can use the app to easily reclaim gigabytes of free storage space in just a few clicks. For example, scan and remove system/iTunes/Photo junk, identify large old files that are safe to delete, uninstall useless third-party apps in batch, etc.

One particular section we like about CleanMyMac is the “Maintenance” module, which is packed with 7 useful utilities that help fix various common Mac issues, such as speed up Mail, verify startup disk, repair disk permissions, flush DNS cache, etc. These maintenance tasks are usually for power users, but CleanMyMac makes it easy for us basic users to use as well.

There are also a handful of other super helpful utilities within the app, and it’s up to you to choose to use them or not. We believe CleanMyMac is the best Mac cleanup app out there and we highly recommend it to most of Mac users.

2. Best for Mac Maintenance: IObit MacBooster

What separates MacBooster from other Mac optimization software is its all-in-one concept. You’ll rarely see how one piece of software can achieve so much — protecting your Mac from virus and malware, cleaning Mac disk drive, optimizing Mac startup times, and others. Obviously, IObit wants to position the app as a one-stop maintenance tool for a Mac.

Once you install and run the app, the main interface shows “System Status: Unknown”. All you need to do is clicking the “Scan” button, within seconds or minutes you’ll see an overview report detailing the issues with your Mac system. Well, we have to point out though, that the software over exaggerates the seriousness of certain issues. For example, it detected 5751 issues under Privacy Protection but turned out those “issues” are actually browsing histories we feel okay to keep.

Nevertheless, we still think the app is valuable for many users. In particular, we like the Duplicate Finder feature — which can help you spot out tons of duplicate and similar items (especially pictures) that are safe for removal. And by doing so, you could free up much storage on your Mac. There are also several other great features like Photo Sweeper, Uninstaller, etc. The bottom line: MacBooster is probably the only yet most comprehensive Mac maintenance app you’ll need to keep your Mac secure and fast.

3. Best Cross-Platform Cleaning App: CCleaner Pro

For those of you who just switched to Mac, you probably have used CCleaner back in the PC days. CCleaner was so popular and Piriform claimed it had achieved millions of downloads. But its popularity perhaps has decreased a bit due to the malware hack happened in 2017 (read more from this Time report). Still, it’s a tool loved by many and CCleaner is definitely the number-one tool for cleaning a Windows PC.

Few Mac users actually know that the app is also now available for macOS. Clearly, Avast (who acquired Piriform) wants to replicate the success of CCleaner in the Mac market. CCleaner Free allows you to scan and clean your computer, while the Pro version offers additional real-time monitoring, automatic updates, and premium support.

4. Best Mac Tune-up App: Stellar SpeedUp Mac

Bill itself to be able to “increase the speed of your Mac by up to 25%”, Stellar SpeedUp Mac is another Mac performance app that strives to take a share in the crowded market. The app is well designed with clean interfaces and text instructions. To get started, all you have to do is clicking the “SpeedUp Now” located in the center, and select “Recommended Scan” to continue.

The app then shows you a list of files that are supposed to be deleted, though within the program this action is called “SpeedUp Now”. We found this a bit confusing as cleaning Mac junk files is one thing and speeding up the computer is another, not sure why Stellar Phoenix uses the words interchangeably.

That being said, it’s one of the easiest-to-use programs we’ve tested and some of you may actually like it even though it’s not the fully-packed or powerful optimization apps.

Any other Mac optimizer software that you feel we should include in this list, leave a comment and let us know.
