Free Space On Mac Os X

How to clean up your macOS or Mac OS X hard disk drive?

How to free up storage space on your Mac. Looks like no one's replied in a while. Question: Q: how to free up storage space using OS X Yosemite? How to free up storage space on your Mac Save space by storing your content in iCloud or using built-in tools to find and remove large or unneeded files. Optimized Storage helps you save storage space space by storing your content in iCloud and making it available on demand. Mac OS X: How to free up hard disk space By SK 5 comments Last updated July 24, 2017 This article describes several ways to free-up space on your Mac so that you can increase available space on your computer. Uninstall Unused Applications. Applications can take up large amounts of space. For example, Pages is 266 MB and iPhoto a whopping 1.1 GB. Uninstalling applications in Mac OS X couldn't be simpler – just delete the application by moving its icon to the Trash.

SSD (Solid State Drives) are very fast, stable, and offer great performance. Unfortunately, as compared to HDDs (Hard Disk Drives), the capacity-to-cost ratio is not so good. There are, however, methods to free up hard drives to obtain additional capacity for computer systems, including the macOS. None of these methods can expand the default disk capacity, but in some cases, even several extra gigabytes might help. You can also consider moving your data to an external drive or a cloud storage to free up storage.

Certain data and files are important and you will not want to delete or move them, however, some files are redundant and can be removed without consequences. If you know which files you can safely delete, you can free up this space. Although the Windows operating system is known for inefficient clutter, the macOS also produces unnecessary files that take valuable disk space. In this article, we describe some methods to clean macOS disk space.

Inspect the drive to ensure that the system is running out of free space

Some issues relating to lack of storage might be difficult to determine, and can even be due to fake error logs. So, first ensure that the system is in fact running out of free space. To check available space on a hard drive, there are two methods: 1) access the Apple menu and select About this Mac, or; 2) choose the Storage tab. More detailed information can be found within the Disk Utility feature, which is located in the Applications folder under Utilities. Once Disk Utility is launched, select a drive connected to the Mac.

Begin by cleaning Trash

Once you are sure that the drive is actually full, the next step is to simply clean the computer (as if you were cleaning your home: you empty the trash). Open the Finder menu and choose Empty Trash. Bear in mind that some applications such as Mail, iMovie, iPhoto, and others, have their own Trash. To clean those apps, follow the steps below:

• Mail: click Mailbox, choose Erase Deleted Items, select In All Account and Mailbox, and finally click Erase Junk. Alternatively, to avoid permanently losing your files, choose to archive your emails by following the steps below.
• iPhoto: click on iPhoto from the menu at top of the screen and choose Empty iPhoto Trash.
• iMovie: click on File from the menu on top of your screen, select Move to Trash or File, and then choose Move Rejected Clips to Trash

Clear unnecessary Downloads

The Downloads folder stores all files downloaded from the Internet. Often, these are forgotten after use and continue to use storage space. This is an excellent area to address when looking to free up space on your drive. Delete all redundant Download files. Open Finder. In the sidebar, choose the Downloads folder. Disk image (.dmg) files commonly occupy most unused storage space.

Remove unused applications

Unused apps in isolation might not take up a great deal of space, but the amount of hard drive storage used by them collectively can be significant. Furthermore, removing apps on Macs is simple, especially those installed through App Store. To delete them, open Launchpad and click and hold the icon of the program you wish to remove. When the icon starts to animate, click the delete (x) button. To delete any other app, drag the icon to Trash, and then empty Trash.

Make space without losing any data

The best way to gain extra space on the Mac is to move non-executable files such as photos, movies, documents and any large files, to additional external storage, for example, an external drive, USB drive, DVD/CD drive, or cloud storage.

Compress large items

Another method to obtain some free space is to compress files. Compressed files remain on the computer, but occupy less space. On the other hand this can be less efficient than deleting or moving files to external storage. To find the largest files on the drive, open Finder, from the sidebar select the Device (the label you provided), and then type criteria into the search field. When the location of your search appears (for example This Mac), click the add (+) button, click the first drop-down menu, and choose Other. Find the logical size option, enable it, and then click OK.

Choose the 'is greater than' condition and type the amount (i.e. 50 Mb). To compress items, right-click or hold control and left-click it, and then select the Compress 'name' option.

If you are using an earlier version of macOS, click Go from the Finder menu, select Home, choose File, click Find, and then open the Find menu. Find the File size option. Choose the 'is greater than' condition and type the amount (i.e. 50 Mb). To compress items, right-click or hold control and left-click it, and then select the Compress 'name' option. To archive your emails, open the Mail application, select a folder you wish to archive (e.g. Inbox), drag it to the desktop. The mbox folder will appear on your desktop, right-click it or use the control and click combination, and select Compress 'Inbox.mbox'. Now you can delete your messages from Mail.

Delete unnecessary temporary files, system caches, and logs

System stores a number of System logs and temporary files - deleting them will increase the available space on your drive. To clean the system from this type of file, we recommend Combo Cleaner or other third-party applications.

Clear the browser cache storage

Browsers store website data such as cookies and cache information. Cleaning these hidden files might free up storage space. To clean up Safari, simply click Safari on the menu at the top of the screen and select Clear History. Browsers such as Google Chrome and Mozilla Firefox can be cleaned in a similar way.

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.

Understanding What 'Your Disk is Almost Full' Means

What is a startup disk?

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:

• Your Mac's hard drive is 500GB.
• It has one 'disk' on it, so all 500GB of storage is on that disk.
• The disk has an operating system (OS X El Capitan), and user data (apps, etc).
• And since you only have one disk, this is your startup disk: all 500GB.

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.

Why your disk is almost full?

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 clear up storage immediately.

What to do when your disk is almost full?

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 storage, of course. To make more space on your startup disk you will need to:

1. Delete files from your Mac.
2. Move files to an external hard drive or cloud storage.
3. Or install a second internal hard drive on your Mac.

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.

What's Causing 'Your Disk Is Almost Full' Alert?

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:

1. Hover on the Dock at the bottom of your screen and open Finder.
2. Click on 'Finder' in the menu bar at the top of your screen.
3. Then select 'Preferences…'
4. In the window that opens, checkmark the 'Hard disks' checkbox.

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: https://free-tags.mystrikingly.com/blog/how-to-install-google-chrome-in-windows-7.

To make 100% sure that you know what drive is your startup disk, follow these steps:

1. Click on the Apple Icon in the menu at the top-left of your screen.
2. Select 'About This Mac.'
3. Under macOS, you'll find a version number. Mine is 10.15.1, like so:

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.

What is taking up all of my startup disk space?

Now that we've identified our startup disk, let's take a closer look at how to clear up space on Mac:

1. Click the Apple Icon in the menu at the top-left corner of your screen.
2. Choose 'About This Mac.'
3. Click Storage.
   Note: If you are running an older version of OS X you may have to first click 'More Info…' and then 'Storage'.

Take a look at my hard drive disk:

I've got 500GB of storage, and about 275GB of it is free.

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.

Free Up Space On Mac Os X

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! Mac tools wrenches.

1. Clear system storage on Mac

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.

1. Search for large ZIP/RAR archives in Downloads
2. Open your Desktop (Command + F3) and delete screenshots
3. In Applications, sort your apps by size. Delete the largest ones
4. Get rid of system junk files with a free version of CleanMyMac X
5. Restart your Mac to free up RAM.

2. Clean up cache files on your Mac

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 clear storage. And don't worry, your Mac will create fresh, new ones after you restart your Mac. To remove caches:

1. Open a Finder window and select Go in the menu bar.
2. Click on 'Go to Folder…'
3. Type in ~/Library/Caches
   Delete the files/folders that are taking up the most space.
4. Now click on 'Go to Folder…'
5. Type in /Library/Caches (simply lose the ~ symbol)
   And, again, delete the folders that take up the most space.

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.

Oh, and once you're done with this list, restart your Mac so it can create these new cache files.

3. Get rid of localization 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:

1. Open a Finder window.
2. Go to Applications.
3. Ctrl+click on an application.
4. Select 'Show Package Contents.'

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.

https://soft-bb.mystrikingly.com/blog/mac-player-iina. 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.

4. Delete duplicate files

Even if you have the most organized Mac on a planet, duplicates happen one way or another. It can be a file you've mistakenly downloaded twice or a mail attachment you've opened several times. Regardless of how they appeared, those files sit on your Mac and gobble up storage.

But finding and deleting them is a time-consuming process if you do it one by one. So here's what you can do to save up time:

Even if you have the most organized Mac on a planet, duplicates happen one way or another. It can be a file you've mistakenly downloaded twice or a mail attachment you've opened several times. Regardless of how they appeared, those files sit on your Mac and gobble up storage.

But finding and deleting them is a time-consuming process if you do it one by one. So here's what you can do to save up time:

1. Open the Finder app on your Mac
2. Move cursor over File and click New Smart Folder
3. Click the '+' button in the upper right corner and choose the type of files you want to see
4. Now sort them by name to quickly spot duplicates.

Remember to pay attention to the date of creation to make sure you keep the true original, not the copy.

While this is the best way to remove duplicates manually, it takes lots of your time and dedication. It'd be much easier to leave this to Gemini 2: The Duplicate Finder.

This app quickly scans your Mac for duplicate and similar files and allows you to delete them within minutes. It keeps your originals safe and helps you easily retrieve files deleted by accident.

5. Remove old iOS backups

Backups can tend to take up a lot of space. You can find and remove them by:

1. Launching a Finder window.
2. Clicking 'Go' in the menu bar.
3. Selecting 'Go to Folder…'
4. Then, type in ~/Library/Application Support/MobileSync/Backup/

Get rid of all the old, outdated backups your Mac has been storing for a bit more extra space.

6. Remove iOS software updates

You can find all the unnecessary data for your devices by:

1. Opening Finder.
2. Selecting 'Go' in the menu bar.
3. Clicking on 'Go to Folder…'
4. And entering for iPad ~/Library/iTunes/iPad Software Updates
   or entering for iPhone ~/Library/iTunes/iPhone Software Updates

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.

7. Remove unnecessary applications

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.

8. Clean up your photo library

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 caches. 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:

1. Open Finder and navigate to your Photos library (normally, it's in the Pictures folder).
2. Ctrl+click your Photos library, and select 'Show Package Contents.'
3. Open resources, and then modelresource.

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.

9. Clean up your Downloads, Movies, and Music folders

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.

How to archive/compress a file

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:

1. Ctrl+click the file you want to compress (recommended for movie files).
2. Select, 'Compress .'

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.

10. Clean your Desktop

'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.

11. Empty out the Trash (No, we're not joking…)

Seriously: It may sound incredibly basic, but it could clear a surprising amount of storage. 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:

1. Ctrl+click your Trash in the Dock.
2. Select 'Empty Trash.'
3. And click 'Empty Trash.'

And, the easiest step is done.

A few more tips to clear storage on Mac

1. 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:

2. Erase your Junk Mail

Open your Mail app, and click Mailbox in the upper menu. Here you can erase spam and already deleted items.

3. 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.

Full Startup Disk Prevention

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 cleared up:

1. Click the Apple Icon in the menu at the top-left corner of your screen.
2. Choose 'About This Mac.'
3. Click Storage.
   Note - If you are running an older version of OS X you may have to first click 'More Info…' and then 'Storage'.

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.

Say goodbye to the 'Your startup disk is almost full' message.

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).
