Optimized Storage in macOS Sierra and later* can save space by storing your content in iCloud and making it available on demand. When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically. Each file stays right where you last saved it, and downloads when you open it. Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.
* If you haven't yet upgraded to macOS Sierra or later, learn about other ways to free up storage space.
Being a tried, tested and ‘consumer certified’ Macbook speed up software for over 5 years now, the software package has been upvoted by over 25K satisfied customers from around the world as the best Mac cleaner software that tweaks, tunes up and optimizes your. Mar 16, 2018 The Mac needs to contribute RAM to display each item on your desktop, so the more cluttered your Mac desktop is, the less computing resources your macOS has to use on other tasks. One way to do this is to give your documents and files a spring clean - move them manually every month.
Find out how much storage is available on your Mac
Choose Apple menu > About This Mac, then click Storage. This is an overview of available storage space on your Mac, as well as the space used by different categories of files:
Click the Manage button to open the Storage Management window, pictured below. (The Manage button is available only in macOS Sierra or later.)
Manage storage on your Mac
The Storage Management window offers recommendations for optimizing your storage. If some recommendations are already turned on, you will see fewer recommendations.
Store in iCloud
Click the Store in iCloud button, then choose from these options:
- Desktop and Documents. Store all files from these two locations in iCloud Drive. When storage space is needed, only the files you recently opened are kept on your Mac, so that you can easily work offline. Files stored only in iCloud show a download icon , which you can double-click to download the original file. Learn more about this feature.
- Photos. Store all original, full-resolution photos and videos in iCloud Photos. When storage space is needed, only space-saving (optimized) versions of photos are kept on your Mac. To download the original photo or video, just open it.
- Messages. Store all messages and attachments in iCloud. When storage space is needed, only the messages and attachments you recently opened are kept on your Mac. Learn more about Messages in iCloud.
Storing files in iCloud uses the storage space in your iCloud storage plan. If you reach or exceed your iCloud storage limit, you can either buy more iCloud storage or make more iCloud storage available. iCloud storage starts at 50GB for $0.99 (USD) a month, and you can purchase additional storage directly from your Apple device. Learn more about prices in your region.
Optimize Storage
Click the Optimize button, then choose from these options.
- Automatically remove watched movies and TV shows. When storage space is needed, movies or TV shows that you purchased from the iTunes Store and already watched are removed from your Mac. Click the download icon next to a movie or TV show to download it again.
- Download only recent attachments. Mail automatically downloads only the attachments that you recently received. You can manually download any attachments at any time by opening the email or attachment, or saving the attachment to your Mac.
- Don't automatically download attachments. Mail downloads an attachment only when you open the email or attachment, or save the attachment to your Mac.
Optimizing storage for movies, TV shows, and email attachments doesn't require iCloud storage space.
Empty Trash Automatically
Empty Trash Automatically permanently deletes files that have been in the Trash for more than 30 days.
Reduce Clutter
Reduce Clutter helps you to identify large files and files you might no longer need. Click the Review Files button, then choose any of the file categories in the sidebar, such as Applications, Documents, Music Creation, or Trash.
You can delete the files in some categories directly from this window. Other categories show the total storage space used by the files in each app. You can then open the app and decide whether to delete files from within it.

Other ways that macOS helps automatically save space
With macOS Sierra or later, your Mac automatically takes these additional steps to save storage space:
- Detects duplicate downloads in Safari, keeping only the most recent version of the download
- Reminds you to delete used app installers
- Removes old fonts, languages, and dictionaries that aren't being used
- Clears caches, logs, and other unnecessary data when storage space is needed
How to free up storage space manually
Even without using the Optimized Storage features of Sierra or later, you can take other steps to make more storage space available:
- Music, movies, and other media can use a lot of storage space. Learn how to delete music, movies, and TV shows from your device.
- Delete other files that you no longer need by moving them to the Trash, then emptying the Trash. The Downloads folder is good place to look for files that you might no longer need.
- Move files to an external storage device.
- Compress files.
- Delete unneeded email: In the Mail app, choose Mailbox > Erase Junk Mail. If you no longer need the email in your Trash mailbox, choose Mailbox > Erase Deleted Items.

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:
- Upgrade hardware;
- 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:
“…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
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.
