Choose Apple menu About This Mac, then click Storage. Each segment of the bar is an estimate of the storage space used by a category of files. Move your pointer over each segment for more detail. Click the Manage button to open the Storage Management window, pictured below. Delete Large Files on your Mac. Instead of deleting a hundred small files and images, first of all, let. First, one can go to Finder Go Utilities, then double-click on the Disk Utility icon. Next, there's a keyboard shortcut to get to the Utilities folder — Command + Shift + U from the Finder. Or, since you're running macOS Sierra, you can just click on the Siri icon and say 'Launch Disk Utility'. Hello, For the past month or so, my Macbook has been bombarding me with 'running out of space' messages. I have read countless articles and forums, but I still have not solved the issue. System takes up 90 GB of my 120 GB. I tried downloading DaisyDisk and OmniDiskSweeper, but they only show. Use command - docker system prune -a This will cleaned up total Reclaimable Size for Images, Network & Volume. This will remove all images related reclaimable space which are not associated with any running container. Run docker system df command to view Reclaimable memory.
SSDs are great—they're fast, durable, and reliable—but they're also expensive, which results in many of us not having as much storage built into our Macs as we'd like. Particularly for those who watch videos in iTunes or take a lot of photos, it's all too easy to run out of space on your Mac's internal drive.
MacPaw's CleanMyMac X is a great solution for those who don't mind its $35 price tag. This utility can help you identify and remove unnecessary data to free up space. It can ferret out forgotten downloads, old videos, mammoth folders, bloated caches, outdated iOS updates and backups, copies of iOS apps, and more. It also boasts other features that can improve performance, protect your Mac from malware, and keep your apps up to date.
But if you want to go the belt-and-suspenders route, you can use Apple's built-in tool for cleaning house: Storage Management. The legend of isaac mac os.
Apple hid Storage Management inside the System Information app, but there's a shortcut for accessing it. Choose Apple > About This Mac, click the Storage button, and then click Manage… but wait! Before you click Manage, look at the About This Mac window's Storage view.
Hover over each colored bar to see how much space is taken up by a particular type of data. The white space at the end of the bar shows space that's still available. You can't do much here, but the view gives you a quick overview of your usage.
When you click Manage, System Information launches, and the Storage Management window appears. (You can also open System Information manually and choose Window > Storage Management.) In the sidebar at the left, ignore Recommendations and look at the rest of the categories, particularly Applications, Documents, and iOS Files. The specific categories will vary a bit between Macs, depending on what apps you use, but they correspond to the colored bars you saw in the About This Mac window's Storage view.

Applications
The Applications category lists your apps and is sorted by size by default. But try clicking the column header for Kind and scrolling down. You can probably trash most apps tagged as Duplicates or Older Versions. Similarly, click the Last Accessed column header to see which apps you haven't launched in years. Many of them can probably go. Plus, you can redownload anything tagged as coming from the App Store, so you can toss those apps to save space.

Documents
In Documents, you'll see three buttons: Large Files, Downloads, and File Browser. Large Files focuses on files over 50 MB in size, Downloads displays the contents of your Downloads folder (much of which you likely don't need), and File Browser gives you a column view that's sorted by file size and shows sizes next to each item. It's great for trawling through your drive to see what's consuming all that space.
In any of these views other than File Browser, hover over any item to see an X button for deleting the file and a magnifying glass button that reveals the file in the Finder. To delete multiple files at once, Command-click or Shift-click to select them and then press the Delete key to remove them all at once. Storage Management gives you the combined size of all the selected files and warns you before deleting the files, so you can use this technique to preview how much space a multi-file deletion will save.
In File Browser, select one or more files and either drag them to the Trash icon in the Dock, or press Command-Delete.
iOS Files
If you've used iTunes to manage iOS devices in the past, pay special attention to the iOS Files category. It shows any device backups and software updates that are stored on your Mac's drive. If you still use iTunes to back up your device, it's worth keeping the latest backup of devices you still use, but many people have obsolete backups and unnecessary updates kicking around.
Other
As noted before, the rest of the categories here may vary depending on what apps you use. With Books and iTunes, you can remove content that you've purchased, since you can download it again. With Mail and Photos, Storage Management merely tells you how much space the app's data occupies and lets you enable space optimization (downloading only recent attachments for Mail, and keeping only optimized photos on the Mac). To save more space, you must delete unnecessary data from within the app itself.
If your Mac's drive is filling up—if it has less than 10 percent free space—consider using the Storage Management tools to search out and delete files that are wasting space. To be safe, make a backup first!
Perfection is impossible, no matter how much apple you have on your back. So, it seems like a new and very important bug has been found in macOS. Especially, someone who can ruin your Mac space if you ignore it, and that MacOS may be increasing the size of your image library for no reason. And all of this is due to an option that many of you will already know, especially if you're using an iPhone or iPad.

According to the developers of the multimedia NeoFinder browser, the findings are shared by MacRumors, the process of converting images in HEIF format, which captures the iPhone, to JPG can take up more space than necessary. This is will occur when not requiring the option to save the original files which can be obtained when importing photos from iPhone using Image Capture.
For each import file with this application and option is disabled an additional 1.5 MB is included, reaching for optical properties when the image value is high. And all of this was achieved while the NeoFinder development team was working on ways to better use the metadata. When looking at an image with a hexadecimal editor, they found many lines of code other than content that increased the size.

This is an error it looks like it's still in these latest versions macOS, and only happens when images are transferred from iOS devices. Hopefully, given the price Apple charges for storage on their devices, it can quickly resolve this bug. Alternatively, the photos can end up with limited storage for most Mac users.
