Reduce App Storage On Mac

Our resident Mac Help guru, Peter Cohen, previously told us about the 'Other' storage category on Mac computers and what it catalogs: In short, you're seeing space taken up by plug-ins, documents, and caches stored by OS X.

Generally, each iOS app has its own documents and data, so guess, if we gather all apps data in a bucket, then it would produce a large size of data’s.

It's worth noting that these files aren't normally harmful or wasteful to your computer's system; most are intended to help your Mac run efficiently, and ideally, you shouldn't ever have to clear out your Other files. Unfortunately, they can quickly clog up a computer low on storage — especially if you're storing a large number of iPhone or iPad backups.

Whether you're looking to free up space on your hard drive or just want to do some spring cleaning, here are some simple steps to get your Mac free and clear.

A note on what happened to 'Other' space in macOS Sierra and higher

When Apple added its storage management feature to macOS Sierra, called Optimize Storage, it reorganized what 'other' storage is and where it's located on the Mac. Much of it has been divided out through other categories so it's easier to find and remove.

The 100GB of Other storage I used to carry on my iMac is whittled down to just 5GB. You can still clean out old and unnecessary content from your Mac with macOS Sierra and High Sierra by using Optimized Storage. It's just a little easier to find those unused files than it was before.

A lot of the features of Optimized Storage remove content from your Mac and store them in iCloud. If you're concerned with how much storage you're using up in iCloud, you can customize or disable some Optimized Storage features to keep a balance between what's on your Mac and what's in iCloud.

What's this 'Purgeable' category all about?

If you check your system storage graph in macOS, you'll probably discover a category called Purgeable. This is part of Apple's Optimized Storage service. When you move your Documents into iCloud (part of the Store in iCloud component) and your hard drive gets low on storage, only recently opened files are kept on your Mac. Older documents are stored in iCloud, while a shortcut icon is kept on your Mac (files are automatically re-downloaded to your Mac as soon as you open them). The Purgeable files are what Optimized Storage will move to iCloud and delete from your hard drive only if your hard drive starts to get full. Purgeable files also include caches and temporary files that used to fit into the Other category, which will also be deleted as your hard drive starts to fill up.

Though your Other storage might have been spread out across categories in macOS Sierra and higher, you can still follow the below steps to manually clean up your Mac and get rid of unnecessary files.

How to check your storage space on your Mac

If you are concerned with how much storage space you have remaining on your Mac computer, you can check its usage folder to see how much space each category is taking up, including Other.

  1. Click on your desktop or the Finder icon from the Dock.
  2. Select the Apple Menu icon in the upper left corner of the screen.
  3. Click on About This Mac.

  4. Select Storage.

Your Mac breaks down its storage categories as follows: Apps, Movies, Photos, Audio, Backups, and — that annoying, undescriptive category — Other.

How to remove cached files

Now that you know how much space your Other files are taking up, it's time to reduce their footprint on your Mac. You can start by removing items you don't need, including caches for your web browser, saved Apple Music streams, and photo previews.

A note on deleting cache folders: You only want to delete old and unnecessary files, as current cache files store your preferences. We strongly recommend only deleting cache files from old apps.

  1. Click on your desktop or select the Finder icon from the Dock.
  2. Select the Go menu in the upper left corner of the screen.
  3. Click on Go to Folder.

  4. Type ~/Library/caches into the text box. A list of caches from active apps will appear on your desktop.

  5. Select the app folder you wish to remove the cache from.
  6. Right-click (or control-click) on the app folder.
  7. Select Move to Trash.

How to remove downloaded files

Chances are, your Downloads folder is stuffed with Other-type files, including installer packages, documents, and folders you have already made copies of somewhere else. If you want to make some room on your Mac, it may be time to clean out your Downloads folder.

  1. Click on your desktop or select the Finder icon from the Dock.
  2. Select the Go menu in the upper left corner of the screen.
  3. Click on Downloads.

  4. Select the file you wish to remove.
  5. Right-click (or control-click) on the file.
  6. Select Move to Trash.

If you want to save a file from the Downloads folder but don't want it clogging your drive, consider moving it to an external hard drive or flash drive, or uploading it to an online storage option like Dropbox.

How to delete old device backups in iTunes

If you tend to get new iOS devices fairly regularly, you may have unnecessary device backups stored on your computer via iTunes. Backups take up 4-5GB each, on average; there's no need to hold on to older device backups if you no longer have the device or have it stored in iCloud.

Third-party software that can help

While you don't need any third-party app to 'clean' your Mac, there are some very handy system access tools out there that make it easier to regularly remove unwanted files.

CleanMyMac 3

With CleanMyMac, you have easy access to a list of features that help you keep your Mac free of unnecessary junk. It scans your entire system and recommends files you should delete based on how old they are and whether they are considered unnecessary to your workflow. It's a lot like Apple's Optimized Storage, but with a few additional features. My favorite is the recommendation to delete all content related to an application. Sometimes, you'll end up with a couple of files left behind by an app when you delete it. CleanMyMac provides a one-button purge of everything associated with that app.

DaisyDisk

DaisyDisk scans your Mac and gives you a pie chart that makes it easy to see what files are using up the most space. You can identify files that are in the Other storage category and drag them to the delete box.

Onyx

Onyx is a robust Mac system access tool that, in-part, can delete caches, logs, temporary items, and other files that find their way into the Other storage category.

Cocktail

Cocktail is another useful system access tool that you can use to clear caches, purge memory, and manage hidden Apple app settings, which might be automatically sending files into the Other category abyss.

National COVID-19 server to use Apple and Google's API, hosted by Microsoft

The Association of Public Health Laboratories has announced it is working with Apple, Google, and Microsoft to launch a national server that will securely store COVID-19 exposure notification data.

“No matter what I do, my Mac is still slow”, an average tech-consultant hears this phrase multiple times a day. Give a person even the most powerful computer, and pretty soon it will be cluttered with apps, extensions, and things that are too much for it to handle. To reverse it, one has to go back and сlean up the mess, removing memory agents one by one. Prepare for a fight — every byte of memory is at stake. So let’s put your Mac on a diet and get it more free RAM to breathe freely.

First, remove desktop clutter. Get a combination of Setapp apps that clear away unneeded desktop files.

“Your system has run out of application memory”

How do you know your Mac is low on memory? Floating “rainbow wheels” aside, you may notice your Mac now takes ages to load. You’ll also see many browser applications crashing. You’ll be also thrown warning messages as “Your system has run out of application memory”. To help it, you should first visit the Activity monitor to see memory usage on Mac.

How to check RAM usage on Mac

Go to Applications and type in Activity Monitor in the search bar. This invokes a good old Activity Monitor that should tell how much free memory you’ve got left.

A shortcut to open Activity Monitor:

Press F4 and start typing Activity Monitor in the search bar.

I’ve attached a screenshot from my Mac and as you can see my memory usage almost reached full capacity. Here’s what it all means:

App memory: taken by apps and processes
Wired memory: reserved by apps, can’t be freed up
Compressed: inactive, can be used by other apps
Swap used: memory used by macOS
Cached files: memory you can really use

Notice the colored graph under Memory Pressure. If your graph is all but red and yellow, your Mac is really gasping for fresh memory. It seems counter-intuitive, but “available memory” your Activity Monitor is not that important after all. In fact, it’s a system intended behavior to use all memory resources when available. On the contrary, the Memory Pressure graph is much more telling, so grow a habit to check this graph in the Activity Monitor every now and then.

How to check CPU usage on Mac

Open the CPU tab in Activity Monitor to keep in check CPU-heavy processes. Normally an app would be using 0-4% of CPU. If it takes abnormally more than that, go inside that particular item in the list and press the Quit button.

How to free up memory on Mac

Tip # 1. Remove Login Items to lower Mac memory usage

Login items are programs that load automatically upon Mac startup. Some of them covertly add themselves to the list and this is no good. If you’re looking to free up RAM, they are the first candidates for deletion. Don’t worry, you’re not deleting the app itself, you just stop it from auto-launching every time.

So, to remove Login Items and at the same time reduce your memory usage of your Mac, you need to:

  1. Open System Preferences and select Users & Groups.
  2. Click your nickname on the left.
  3. Select the Login Items tab.
  4. Check programs you don’t want to load as your Mac starts.
  5. Press the “–” sign below.

Now, you won’t see these apps pop up the moment you turn on your Mac. Although this method doesn’t require some superpowers of yours, some special Mac optimization and memory cleaner tools may do the job faster and ensure the smooth performance of your Mac. CleanMyMac X is an excellent example of such software. Here’s how to disable Login Items with CleanMyMac X:

  1. Download it for free and go to the Optimization tab.
  2. Check Login Items to see the list of apps that get opened when you start your Mac.
  3. Click Remove.

As you’ve already come to the Optimization module of CleanMyMac, you can also fix hung apps and heavy memory consumers there. In this way, you’ll free up the solid amount of RAM on Mac — 100% free of charge.

Tip # 2. Free up disk space if Mac is low on memory

Storage

The available space on your Mac’s drive translates into virtual memory. This comes to save you when you’ve run out of physical RAM. So now your computer relies on your hard drive space to keep your apps going.

The classic geek rule of thumb holds it that you should keep at least 20% of disk space on your startup drive. Not only this potentially reduces your future spending on iCloud storage but it also keeps your Mac speedier.

What to delete to free up space:

  • Large unused files, like movies
  • Old downloads
  • Rarely used applications
  • System junk

But here’s a simpler solution to save your time — clean up your drive with CleanMyMac X— the app I’ve mentioned above. Many users recommend it as an excellent way to free up more space because it searches for large & old files, useless system files, Photo junk, mail attachments and shows everything you can safely delete. Interestingly, it finds about 74 GB of junk on an average computer.

Extra trick: How to free up RAM on Mac with CleanMyMac X

If you have downloaded CleanMyMac, you may also take advantage of its amazing feature — the ability to free up RAM in a few seconds. Try this next time you see “Your system has run out of application memory” message.

  1. Go to the Maintenance tab on the left.
  2. Click Free Up RAM.
  3. Click Run.

As simple as that!

And you can do it even if you download a free version of the app.

Tip # 3. Clean up your Desktop

This tip always comes at the bottom of instructions and unfairly so as it is quite effective. Without even looking at your Desktop I would assume it’s cluttered with mountains of icons. Thing is, your macOS was designed in a way that it treats every Desktop icon as a little active window. The more icons, the heavier memory usage on Mac. So in order to release available memory resources, it’s recommended to keep your Desktop clean.

You don’t have to do it all by yourself. With apps like Declutter and Spotless, every desktop cleaning session will be scheduled in advance and executed automatically. Your only job is to define the rules on how your files should be organized.

Tip #4. Clear cache files

Another way to free up RAM on Mac is to clear it of cache files. Of course, it won’t save you gigabytes of space, but deleting cache regularly, you can help your Mac run faster and avoid system issues.

So, to remove cache files on your Mac, you need to:

  1. Open Finder.
  2. From the Go menu, select Go to Folder.
  3. Type ~/Library/Caches in the field and press Go.
  4. In the window that appears, you will see all your cache files.
  5. Press Command+A to select all files or delete files one by one.
  6. Enter your user name and password to confirm.

If you find some files still in the folder after you emptied it, maybe you have some windows open on your Mac. Just like that, you can save up some space on your Mac. Don’t forget to empty the bin afterward.

Tip # 5. Tune up Chrome’s Task Manager

Although Google Chrome is not the one to blame for massive memory usage, it can indeed affect your Mac's performance. If you use Chrome as your primary browser, you probably have many windows opened there. Chrome runs a lot of processes to ensure a fast browsing experience for you. So, it uses your RAM for storing your tabs, plugins, and extensions. Look at how many entries Google Chrome has in Activity Monitor:

The question then arises, 'Why does Chrome use so much RAM?' The thing is that each process is responsible for a separate plugin or extension of your browser. For example, when a tab unexpectedly falls, you need to refresh it to continue your work there. If one process were responsible for all tabs and extensions, you would need to restart the whole browser instead. Can you imagine how many times would you do that? That’s the proper answer to why Chrome uses so much RAM.

I’ve been using Chrome for some years only to discover (recently) that Chrome had a task manager of its own. You can use it to force quit memory-heavy processes in the browser. It’s a handy tool because it lets you see how a page weighs on CPU usage on a Mac.

  1. Go to Chrome settings (dotted icon in the top right corner)
  2. Click More tools -> Task Manager

To free up even more RAM, close the GPU process. The GPU Process, though helpful in theory to accelerate pages, eats up a considerable amount of memory. Click to end it to free up RAM on your Mac.

Tip # 6. Manage RAM usage with CleanMyMac X menu

CleanMyMac X has another useful and convenient feature for managing your Mac’s performance and memory usage. As you install CleanMyMac X and start it for the first time, it’s icon will appear in your menu bar. Click the icon to open the CleanMyMac X menu. Here you can find updates on the current condition of your Mac and perform quick tweaks to increase your Mac's speed. Whenever you feel like your Mac underperforms, open the CleanMyMac X menu to check how much RAM is available and free it up as well.

Tip # 7. Close Finder windows

Okay, suppose you’re still asking yourself, how do I clear RAM on my MacBook Pro/MacBook Air. The next trick is as magical (you’ll see for yourself) as it is time-saving. It’s no secret that each window in the Finder eats up RAM. But how many open windows are there? Some of them are collapsed or stacked in some blind spot on your screen. This Finder command merges all your windows into one. See how to do it:

Click on Finder > Window > Merge All Windows

Now you can manage Finder windows more effectively and free up memory on MacBook.

What else you can do to minimize memory usage on Mac

I’ve saved the easiest tips for the end, as long as these ones are self-explanatory.

  • Replace AdBlock (very memory-demanding) with a lighter extension
  • Keep fewer opened tabs in the browser
  • Restart your Mac more often to free up RAM
  • Close all hung-up print queues

That was my take on how to make your Mac a bit speedier to use. If you’re looking for more guidance, check simple ways to speed up your Mac.
