Caches and temporary files can include things like web browser cache and history, messaging cache, app specific temp files and caches, partially completed downloads, and much more.
You’ve probably heard and seen the term 'cache' used on your Mac but do you know what it is?
Cache files are basically temporary data stored on your hard drive and used to speed up processes. For instance, Safari will download images on a webpage into cache so that next time you visit the site you don’t have to download the images again.
For best results, if you create additional iTunes libraries, don’t name the new libraries “iTunes” or “iTunes Music.” Make sure each iTunes library has its own unique name so you’ll know which is which.In each library you create, you can select different preferences for the iTunes Media folder, the types of content that are displayed, parental settings, and the library name.

There are many reasons to remove old cache from your MacBook and disk space issue is only one of them. So what are the other benefits ?
Are you ready to reclaim space on your Mac? Let’s go!
There are roughly three main types of caches you can clean on your Mac:
This article will go over cleaning up all three.
Now, when it comes to clearing cache on Mac, there are two ways you can do it. You can clean them up manually step-by-step, or you can clean them in second with a cleaning utility like CleanMyMac X. If you want to clear cache on your Mac right now, we suggest doing it the easy way:
That’s it, all cache files cleaned! CleanMyMac X works on all systems, including the latest macOS Catalina. You can download CleanMyMac X for free here and try.
However, if you’d like to clean them all manually, follow the steps below.
Potential space reclaimed from junk - Up to 70%
As you can see, a single user cache folder on my computer takes up enormous 1.6 GB of space. And that’s just one folder out of hundreds. That means a good cleaning could free up gigabytes of free space and speed up your Mac in the process.
To clear your user cache, do the following:
Now, repeat the same steps above, but substitute…
~/Library/Caches with… /Library/Caches
Make sure that once you have finished clearing out these caches for additional hard drive space, you empty out your Trash. To do this, Control-click on the Trash icon in the dock and select “Empty Trash.” Restart your Mac afterward so your Mac can begin to create new, fresh cache files.
To help you make sense of your Library folder here's a brief explanation what each sub folder stands for.
Caches
Temporary data created by apps and websites. Your apps keep generating cache files for as long as they are active. Relying on such pre-loaded content reduces memory load and speeds up data exchange.
Preferences
Prererences folder is where you’ll find customized settings for your apps. Sometimes, there is a need to reset an app and delete its corrupted Preferences file. Preference files always end with .plist — so they are easy to spot and delete.
App support
App support folder contains large pieces of app data, like game saves. App support files may remain on your Mac long after you’ve deleted the app itself. That’s why “cleaners” for system junk were invented.
Containers
Containers folder is an exchange buffer that apps use to communicate with one another. This is often referred to as “sandboxing.” Containers folder is automatically emptied after you restart your Mac.
If you aren’t comfortable with the risk of deleting user cache manually, a specialist cleaning app CleanMyMac X can do it for you. It will only remove files you don’t need and will find up to 7x more temporary cache files to remove from all over your system.
Potential space reclaimed from junk - Up to 10% (manual methods) or 15% (using cleaner)
Next up we’re looking at your system cache files. These hidden cache files are mainly created by the apps that run on your Mac.
What is app cache? In short, it’s any media downloaded by the apps you use in order to work faster and not load it every time you open the app. Do you need it? It’s debatable, but app cache takes up disk space and can be cleaned.
You can delete app cache on Mac in the same way as user cache, by going to ~/Library/Caches and removing the insides of the folders with the app name.
Proceed with caution! Not all app cache can be safely cleared. Some app developers keep important user info on cache folders. Backing up a folder before you delete is always a good idea. If everything works fine then you can delete the backup later.
To be on the safe side, use CleanMyMac, it works with a Safety Database and knows how to clear app cache safely. As if that wasn’t enough it will also remove more junk than manual methods.
Every time you do image manipulations, like rotating a picture, its additional copy is created on your drive. In this manner, just 4 rotations are enough for an image size to grow from 2.5 MB to 10 MB of disk space taken. If you edit photos and videos on a regular basis, you may notice that your editor application also keeps temporary data — like intermediate version of your files.
Potential space reclaimed from junk - Up to 15%
We all love to surf the web but every site we visit adds to the growing browser cache. Clearing your browser cache doesn’t just free up space, it will can also clear your browsing history to secure your privacy.
Browser cache temporarily stores website data such as images, scripts, and other stuff, in order to make your browsing faster when you revisit the same site. If you’re worried about your privacy or want to hide pages you’ve visited, you can clear your Internet cache (or browser history). Also, resetting your browser cache will potentially help to get rid of 404, 502, and other errors caused by corrupted cache.
Each browser has its own cache location, so the process of clearing is different in each case. For instance, Chrome cache location is in Settings, Safari stores its cache in Privacy, and Firefox cache location is History tab.
Here’s a quick introduction into how to delete browser cache on Mac.
Here’s how to clear browser cache in Chrome manually:
Here’s how to delete cache in Firefox manually:
In the same menu, checkmark Override automatic cache management and limit the cache size in MB. Go with the default amount of 350 MB, which is enough for most users' needs.
TIP:
If for some reason you cannot open a web page, try putting cache: in front of the URL address. This redirects you to the site’s cached copy.
For example: cache:macpaw.com
It works most of the time and can magically open even the otherwise blocked sites.
Safari is a little trickier than the rest of the browsers. You could remove caches together with all the other website history through History — Clear History in menu bar.
But if you need more precision, here’s how to empty cache on Safari browser:
Make sure you close/quit the browser and restart it after clearing cache. Note, that all your auto logins and predicted websites in the address bar will be cleared.
Manual methods remove most of the browser junk but if you want to remove all of it, from all your browsers at once, there’s a safer and faster method to clear your internet cache on any browser.
Instead of searching all over your Mac to find and remove cache files yourself, you can clear user caches on a Mac using CleanMyMac X. It makes removing cache files as easy as can be.
To get rid of cache files with CleanMyMac X:
And you're done! If you’d like to remove only cache files and nothing else, click on Review Details before clicking Clean. Deselect everything but System Cache Files and User Cache Files, then click Clean.
Instead of clicking between browsers and being limited to what they let you clean, take full control of all your browser cleaning with this simple method:
Cleaning your Mac has never been easier. Download CleanMyMac X and try for free to get yourself a faster, cleaner Mac — without worrying about cleaning the wrong thing.
And if you’re looking to clear just browser cookies, check out this easy one-minute explanation we’ve made for you.
A full startup disk is something that every Mac user will experience. This problem used to be known as “Startup disk full” notification. However, on newer macOS versions this message has been changed to “Your disk is almost full.”
But luckily, it’s a problem that has many solutions. And in this article, we’ll go over:
However, we also understand that some people are short on time and just want to fix startup disk full. So, if you’re not really interested in what it is and why it happens, just skip the next two sections and head to “How to Clean Your Startup Disk”.
Or, even better, if you’re looking how to clear space on Mac, we’d highly recommend a utility called CleanMyMac X. It'll help you clean up gigabytes of disk space in just minutes (you can download it here).
Note: if you’re running macOS Sierra (or higher), it has a built-in option of Optimized Storage that is supposed to solve the problem of the full hard drive by moving files into the cloud.
By clicking 'Manage' you can open the menu and see what Optimized storage offers. However, it moves junk and useless files to the cloud together with your files, and eventually you end up paying for iCloud storage to store junk. So we still recommend getting CleanMyMac and actually dealing with extra files rather than simply moving them.
Now, with all that said, let’s get into what exactly “Your disk is almost full” means.
A startup disk, as taken from Apple Support article, is a volume or partition of a drive that contains a usable operating system. Still confused? Let’s break it down for you.
Your Mac hard drive consists of disks (or partitions). Each disk (or partition) has your Mac data on it, which consists of your operating system, applications, etc. Most Mac users have just one disk but power users may have two or more.
Let’s look at an example of a Mac with only one hard disk:
A Mac with two disks will have the storage divided between them. The Mac drive with the OS on it is the startup disk while the other drive is just used for storage of files. It’s possible to have multiple startup disks, but most Macs will only have one.
This is easy. It’s a lot like why is your fridge full? There is no more space! Your disk is almost full and this is very bad news for any drive. A hard disk should never get beyond 85% capacity (especially a startup disk) as you will experience slowness and errors the further you get above that mark.
If your startup disk is full and you get a message of warning from your Mac, this is a serious indication that you need to free up storage immediately.
So how do you fix your almost full startup disk? The same way you solve the problem of a packed fridge - you need to clear up space, of course. To make more space on your startup disk you will need to:
So, now that we know what a startup disk is, we need to talk about how to fix it. Let’s take a closer look at your disk space to see exactly what is causing your disk to be almost full.
Short version: Take a look under-the-hood of your Mac.
Before we can see what is taking up space on your startup disk, first we have to find it:
After selecting this box, your desktop should now show the hard disks on your mac, in the form of icon(s), like this:
These are disks on your Mac that you can “startup”, this is because they have operating systems on them. If there is more than one of these hard disk icons that show up on your desktop, it means you’ve got multiple hard disks on your Mac. If you only have one, skip the down to “What is taking up all of my startup disk space?” section.
If you have more than one, continue with the next step:
Click on the Apple icon at the top left of your screen System Preferences > Startup Disk.
Here, again, you’ll find your hard disk(s); they’re probably named something like MainSSD or MainHD. It will also display “OS” and the version number of that OS. If you have more than one OS drive, your startup disk should be the one with the latest version of macOS running on it, but we’re going to make sure of that in the next step.
I only have one and it looks like this:
To make 100% sure that you know what drive is your startup disk, follow these steps:
See how my version number in the “About This Mac” window matches the number in my Startup Disk section? Yep — That’s my startup disk. Found yours? Good.
Now that we’ve identified our startup disk, let’s take a closer look at how to clear up space on Mac:
Take a look at my hard drive disk:
I’ve got 500GB of storage, and about 275GB of it is free space.
So, how big is your hard disk? How much free space do you have (if any — *gulp*)? And what’s taking up the most space? It is important to consider drive capacity and data storage needs for future storage plans — we’re not just here to fix the problem, for now, we’re going to make sure you never have this problem in the future as well.
Now that we have the knowledge, it’s time to take action and fix your Mac’s “Startup Disk Full” problem.
Let’s go over 11 things you can do to help fix 'your disk is almost full.' These should also give you other ideas as to how else to fix it — You know your Mac better than we do!
System storage cleanup sounds like a serious undertaking. But, technically, it boils down to just one thing: having the courage to scrap the old files.
Cache files are files that help your Mac run programs a bit more smoothly. Think of them like blueprints for a house: your Mac has the blueprints for how a program is supposed to load/run/look, so it loads it faster; without them, it’d be like building it from scratch. However, over time, these caches can start to take up some serious space. Periodically, removing them can help free up space. And don’t worry, your Mac will create fresh, new ones after you restart your Mac. To remove caches:
Deleting cache files is generally safe for your Mac. And once you delete them, the applications and processes you run on your Mac will generate fresh, new ones. But, when deleting, worry more about removing them based on size rather than just removing all of them.
Also, you can check the /System/Library/Caches folder as well, but it might be better not to touch this folder without knowing what the items are. A utility that correctly cleans up these files (and pretty much everything else on this list) is, you guessed it, CleanMyMac X. It cleans up even your system caches with just a few clicks. By the way, this program is notarized by Apple.
Oh, and once you’re done with this list, restart your Mac so it can create these new cache files.

Localization files are also known as “language packs.” Lots of apps come with other languages that you probably don’t need. To clear up space on your Mac, delete the ones you don’t need:
From here, go to Contents > Resources and look for files ending in .lproj. These are the languages your app has just in case you want to use it in another language, like Spanish (es.lproj). Drag the ones you’ll never use to the Trash.
Again, a safer alternative to this would be to use CleanMyMac X. It gets rid of all of them with a click. No digging through application folders, just a cleaner Mac.

The more recent versions of iTunes create backups of your iTunes Library, whenever you update the application (which, to me, feels like every day). You can trash these old iTunes Library backups by:
They’re all dated, just delete the old ones you don’t need anymore.
Backups can tend to take up a lot of space. You can find and remove them by:
Get rid of all the old, outdated backups your Mac has been storing for a bit more extra space.
You can find all the unnecessary data for your devices by:
Delete downloaded files for any of the devices that you are not using anymore, or ones which software just already updated. Remember that after any of your devices have been updated, you don’t need those files.

This isn’t often overlooked, but definitely under-appreciated. Removing old, unused applications is a great way to get some extra space on your startup disk. Go through your applications folder and get rid of all the apps you rarely use. But make sure you remove them correctly, don’t just drag them to the Trash. If you do, you’ll leave behind tons of leftover parts and pieces, and we’re trying to get back startup disk space — It’ll kinda defeat the purpose, no?
This is another place we’d suggest using CleanMyMac X. To completely remove any application, just launch CleanMyMac X, click Uninstaller, select your application, and then click Uninstall. You won’t have to search all over for development junk that’s left behind when Trash’ing an application. It’s incredibly easy and saves you tons of time.
Photos, photos, photos. Talk about tons of space! First and foremost, select only what you can get rid of, like image copies and maybe some photos that were mistakenly taken. You know, ones of the ground or something?
Ok, once your own files are taken care of, it’s time to get rid of the files your system created. In Photos for Mac, it’s cache files. In iPhoto, it’s service copies. Both are a pain to find, but here’s how you can get rid of them.
Photos cache includes iCloud local copies (created when you view pics from your iCloud photo library on a Mac), Faces cache (generated when you use Faces), and other app-related cache. You’d be surprised how much all that takes up if you regularly use Photos. For OS versions prior to macOS Sierra, here’s the path to locate the cache:
You should now see a lot more folders in your Finder window. Photos cache sits in these folders, but the tricky thing is that it’s really hard to say what is safe to remove and what isn’t. Deleting the wrong file can compromise the performance of Photos, which is why we highly suggest you use CleanMyMac X to clear the cache and system junk. It only removes files that are safe to delete, never a critical file or important image.
You can download CleanMyMac X for free and see how it works, it’s so much safer than cleaning up system junk manually.
Have a closer look at these three folders. You’d be surprised at how many downloads can accumulate when you aren’t paying attention. Clean out anything you don’t need (or don’t know) and organize the rest. It’ll take a load off your mind to know that there’s nothing excess there.
The Movies folder can be a pain, not because you’re searching through tons of files, but it can be difficult to choose what to delete. Personally, I never want to get rid of Top Gun. It’s amazing. I watched it 3 times in a row last weekend. But alas, sometimes you need to make sacrifices for the health of your Mac. Though, what you can do with movies you want to keep is to archive them. So, archive what you wish to keep and remove the rest.
Archiving a file doesn’t mean to store deeper into the abyss of your Mac — but to turn the file into something smaller, into a compressed file (like .zip or .tar). By archiving a file, you shave off some memory. Archiving is essential for things you want to keep on your Mac, but don’t often use, and helps you clear up some space. And that’s what this is all about right? We’re essentially doing the hokey-pokey on your Mac. To archive a file, just:
The last place to sweep through is the Music folder. Find and remove duplicate music files first, and then clean up all the songs you downloaded on a weird Sunday afternoon cleaning the house.
“Clean my desktop… but why?” Because some people’s desktops are hard to look at, that’s why. Organize your desktop and get rid of the stuff you just don’t need on there. It looks better and helps your Mac act a bit faster (I don’t know the rocket science behind this one, but it feels too good to be false). Your Mac doesn’t waste time loading all those icons and junk, just… Just clean it, please.
Seriously: It may sound incredibly basic, but it could free up a surprising amount of space. I forget to do it all the time. The thing is, that when you delete something, your Mac doesn’t remove it — it just moves it to the Trash. Plus, you’ve probably deleted way more than you realize, and all that could be sitting in the Trash, wasting space. So get rid of all that junk by emptying the Trash:
And, the easiest step is done.
Some files often have two or more copies. Check out Gemini 2 — it searches for identical files and folders all across your Mac.
2. Manage your Optimized Storage
This option comes with your operating system starting macOS Sierra. Go to the Apple menu > About this Mac > Storage
Now, click on Manage to reveal the space-saving options:
3. Erase your Junk Mail
Open your Mail app, and click Mailbox in the upper menu. Here you can erase spam and already deleted items.
4. Delete system junk with CleanMyMac X
Again, this is an incredible utility when it comes to cleaning your startup disk. And this app is notarized by Apple, meaning it's safe.
To avoid the annoying “your disk is almost full” error, download the free edition of CleanMyMac X.
Once you've installed the app, click on the System Junk tab. It will clean up caches, logs, language packs, binaries, duplicate photos, outdated backups, Trashes, and more.
We’ve cleaned up a few things on your Mac, and hopefully it’s given you more ideas as to what else you can clean. But, let’s take a look at how much space you saved from cleaning the list above. Remember how we checked your Mac’s free space? Open that window again and see how much space you’ve freed up:
You’ve probably got a bit more space, and you’ll want to keep it that way. The only way to prevent a “your disk is almost full” is by keeping your Mac clean. We’d recommend a complete cleaning every 2–3 weeks.
So, we’ve now covered everything that we wanted to share with you. Hopefully, this has helped you fix that full startup disk problem. Your startup disk should now be quite a bit lighter (we hope).
