If you want to check a Macs disk space and disk usage, this is one of the simplest ways to do so: From anywhere in Mac OS, choose the Apple menu item and select “About This Mac” At the general ‘About This Mac window’, click on the “Storage” tab (or if you’re running an earlier Mac OS X version, click on “More Info” button). Disk First Aid, currently part of Disk Utility, has long been the go-to utility for verifying and repairing a Mac’s storage system. Included as a standalone app with the original Mac OS, it was later folded into Disk Utility when OS X was released. Give your disk a checkup If you’re having problems with a disk, Disk Utility can check the disk and repair problems it detects.

Keeping you Mac's hard drive or SSD healthy is hugely important. By monitoring and checking your Mac hard drive's health, you can anticipate potential problems and prevent potentially catastrophic crashes. How do you know if your Mac is working properly?
Fortunately, there are a number of tools available that allow to to check the health of a drive and fix problems before they become serious.
Best Apps to Check Your Mac Hard Drive Health
One of the best apps for alerting you to potential problems is iStat Menus, available in Setapp. Once you've installed it, iStatMenus sits in your Mac's menu bar and monitors not just your hard drive, but its CPU, RAM and network traffic, among other things.
iStat Menus, and the other disk monitoring tools available for macOS, monitor what is knows as SMART status. SMART stands for Self-Monitoring, Analysis and Reporting Technology and is installed on most hard drives and SSDs. In order to use it, you need software to analyze and display what it finds, and that's where iStatMenus comes in. Check out how to clone mac hard drive.
Monitoring SMART reports won't prevent your hard drive from failing, but it will reduce the likelihood of problems occurring.
Note: As of 2016, Apple no longer allows software tools to check the SMART status of an SSD. So iStatMenus won't repot anything on Macs shipped in 2016 or later.
There are other steps you can take to keep your hard drive or SSD healthy. CleanMyMac X has a number of maintenance routines. While most of them are designed to keep your Mac running smoothly, one of them is an excellent way to keep your hard drive in good shape.
How to verify Startup disk
- Launch Setapp, search for CleanMyMac, and open it.
- When CleanMyMac has launched, look on the left hand side of its window for the Speed section and click Maintenance.
- Click the check box next to 'Repair Disk Permissions' to verify startup disk and then click the 'Run' button at the bottom of the window.
- Click OK in the dialog box that opens. Click 'Run' again. View the result
Identifying bad sectors with Disk Drill
Sectors are blocks of space on a disk drive and bad sectors are blocks that cannot be read because, for whatever reason, they're damaged. When Disk Drill attempts to recover data from a hard drive that's failed or one where you've mistakenly deleted files, it marks sectors it can't read from as bad. That means that it won't try to recover data from them in the future.
You can't fix bad sectors, the drive's firmware should identify them and prevent them from being written to. If there's data stored in them and you need to recover it, you're out of luck. But by monitoring how many of them there are on a drive, you can keep an eye on its health and decide whether it's time to replace it, if the number of bad sector starts to increase quickly.
Disk Check App Mac Ios
Here's how to identify bad sector in Disk Drill:
- Open Disk Drill app in Setapp. When it launches, it will ask if you want to 'Monitor my disks for hardware issues'. Say Yes. If you already have Disk Drill installed but didn't check that option when you launched it the first time, go to the Preferences, click the SMART tab and check the box next to 'Monitor my disks for hardware issues.'
- Start a recovery session. In Disk Drill's main window, select the volume 'Macintosh HD', or whatever you've called your Mac's hard drive. Click Recover. Let the recover session run and complete.
- Check bad sectors. Once the recovery session has completed and saved, go back to the main Disk Drill window. Click the gear icon next to the drive you ran the recovery session on and click the bottom item on the menu 'Specify bad blocks.' This tool is designed to allow you to tell Disk Drill which blocks are bad and you don't want it to scan, but it will also display bad sectors it has identified.
How to avoid problems from an unhealthy hard drive
You should always backup your hard drive regularly, but it's even more important to do it when you suspect your hard drive is having problems. If you identify problems with a hard drive using any of the steps above, you should consider increasing the frequency of your backups and test them to make sure you can recover data if you need to – a backup routine is useless if you can't restore data. You should also consider using Get BackUp Pro to make a complete clone of the drive, that way, in an emergency you can boot from the clone and be back up and running immediately. Click here to read about how to backup your Mac. Get Backup Pro, also available in Setapp, is an excellent tool for making regular backups.
How to recover from a failed hard drive
If it's already too late and your hard drive has failed and lost data, you should try to recover the data before you do anything else.

System cleanup in one click
Make your Mac fast and secure with CleanMyMac X.
Sometimes, you need to know how much storage space in on your Mac. Apple doesn’t make this info readily available because not many of us need to know about Mac storage often enough. It’s really easy to check, though – and there are even some alternatives that give you better options for managing your on-board memory!
People need to check their storage space for a variety of reasons. Sometimes it’s just good device management; sometimes your computer is running slowly, and storage is the first culprit you think of. Ideally, about ten percent of the storage space on your Mac should be free at all times so your computer can run smoothly.
Depending on which model you have, this can be tricky to accomplish routinely. Maybe you need to delete some older apps you’re not using, or the app isn’t supported anymore. Maybe you’re just holding onto old documents you no longer need.
Whatever your use-case, here’s how to check disk space on Mac. Message app on mac not working.
Have your storage controlled with Setapp
Get Setapp, an all-in-one toolkit that prevents your Mac from running low on storage. Crucial housekeeping done for you.
How To Check Storage on Mac
Weather app apple mac. It’s actually really simple to check your device’s memory! Here’s how:
- On the menu bar, click the Apple logo in the top left
- Select ‘About this Mac’
- Select ‘Storage’
This is the easiest method for how to see storage on Mac – but you can go deeper! If you need a closer look at your Mac’s memory use, there are a few ways to go about it.
From the Storage screen, you can select ‘Manage,’ which takes you to a new window. Applications, Documents, Photos, and other sections can be found on the left of this window, and a detailed view of those files on the right.
You can also use Finder! To do so, Open Finder, go to the View menu item in the menu bar, and select ‘Show toolbar.’ You’ll see a new bar at the bottom of the Finder window showing the number if items for the section you have selected on the left-hand pane and the total amount of storage your Mac has available.

Disk Utility is another resource. Open Disk Utility, and it will launch into a view of the volume(s) on your Mac, which also shows how much space is used, and how much is free. (Keep in mind Disk Utility is meant for power users who want to manage their storage, and is a bit of overkill for most users.)
How To Manage Storage in macOS
There are also easy ways to manage the files or applications taking up room on your Mac.
In Finder, select the category from the left side pane, then the application or file you want to delete. Right-click on that file or app, select ‘delete,’ and it’ll be removed. From the System Information menu, simply select the file or app you want to get rid of, and select the ‘delete’ button on the bottom right of the window.
But these two methods often doesn’t solve the issue! One clever way to better manage the storage on your Mac is to use cloud storage options like iCloud, Dropbox, Google Drive, and OneDrive. Apple’s iCloud is woven into your AppleID, and using it is a very straightforward approach; it’s automatically added to the storage options for your Mac!
But iCloud is not the only solution for cloud storage on Mac. If you have something else, CloudMounter is the easiest and best way to manage all your cloud storage containers. It lives in your menu bar for easy access, and shows all your cloud storage options in Finder. It helps your Mac treat cloud storage as a local disk, making access and managing files really simple!
Disk Check App Mac Os
Best of all, CloudMounter uses 256-bit encryption, so your documents are always safe.
If all the menus and file size jargon of Apple’s Finder and System Information options is confusing, we’ve got a great solution for you. iStat Menus is a handy app that also lives in the Menu Bar, and gives a graphical overview of CPU and GPU use in real-time, network connections, and memory use. Instead of dipping and diving through Apple’s hierarchal menus, you can just click on iStat Menus to get the same information in a much better interface!
iStat Menus also allows you to keep the data surfaced directly on your menu bar. Instead of clicking the icon, you can choose to have things like CPU or memory usage as icons so the information is always available in real-time. Awesome!
Get CMM X to keep your Mac clean
Download the best app that deprives your computer of clutter — from file leftovers to unneeded apps. So that your Mac never lacks storage.
Probably the best (and definitely the most powerful) option for managing your Mac’s memory is CleanMyMacX. Like iStat Menus, it has a drop-down window from the menu bar showing details like CPU or memory use, as well as which apps may be kicking your Mac into overdrive.
CleanMyMacX really shines when you open it up. The app scans your system and identifies unused files, random system junk, mail attachments – and also manages your trash bins. It scans for malware, checks for privacy leaks, optimizes your system for speedy performance, and does routine maintenance.
That’s a lot, but we’re not done! An option within CleanMyMacX named ‘Space Lens’ is a lot like Apple’s Finder, only better looking and much easier to use. Here you’ll see all your applications and files divided into sections, and broken into sub-menus. You can also manually delete apps or files.
‘Large & Old Files’ is a feature in CleanMyMacX which – you guessed it – finds large files and files you haven’t touched in a long time. The goal is to help you identify which files might be worth deleting, or at least shuffling off to cloud storage. It even tells you how long its been since you used a file!
But let’s be honest: most of the space on your Mac is probably taken up by apps. And chances are, you don’t want or need most of those apps anyway. This is where CleanMyMacX shines bright! Under the ‘Applications’ menu, you can update and manage apps and extensions with ease.
The ‘Uninstaller’ option is a lot like the ‘Large & Old Files’ option, just for apps. It shows you which apps are old, which may be abandoned (32-bit apps are no longer supported on Mac!), and which are just plain unused. It even shows you how large the apps are, letting you do the quick math on which will free up the most space when deleted.
To get rid of apps or files, simply select them from the CleanMyMacX menu, and select the ‘Uninstall’ or ‘Delete’ option at the bottom of the window. It’s that easy!
Keep your Mac in top shape
Checking and managing the storage on your Mac is simple. While viewing your Mac’s storage is easy to do without having a separate app, there are good reasons to have something beyond Apple’s own options to manage your Mac’s memory.
Apps often have files and folders embedded deep in your Mac’s memory, which don’t always go away when you simply delete the app from Apple’s menus. Sure, you got rid of the main offender, but many apps (like those from Adobe) have nuisance files that linger long after you delete the app.

Similarly, moving an app to the trash bin doesn’t actually delete it. The ‘Trash’ app is little more than a place you put apps you don’t want; it doesn’t delete them. You have to manage your trash bin separately, which can balloon out of control.
CleanMyMacX is a great bet for handling it all. It’s smarter at deleting files, folders, and apps, and gives you a much better view of what may be occupying your Mac’s storage. It also removes associated files for apps you delete.
There’s no silver-bullet solution, though! We also like CloudMounter for those with multiple cloud storage solutions, and iStat Menus is really sharp at surfacing the right data when you need it. Best of all, all three options are available for free as part of a seven day free trial for Setapp, along with dozens of other great apps.
