The solution to disabling the "almost full" and "full" notification is to disable the daemon responsible for it: launchctl unload -w /System/Library/LaunchAgents/com.apple.diskspaced.plist or launchctl stop com.apple.diskspaced Alternatively, if you only want to prevent the "almost full" from appearing so often then you can lower the GB threshold via: ...

It's the folder where iTunes saves the backUps of your iDevice. And it takes so much space because each time you sync a device, previous backUps are not deleted. Deleting the folder will, then, mean losing those backUps. Doing this regularly is advised for saving HD space. Just make sure to make a new backUp afterwards, and that you won't need those ...

DaisyDisk (Free Trial, $9.99) DaisyDisk is sort of like WinDirStat for Windows, in that you can see your files as a visual hierarchy and find out which ones are taking up the most space. Where Daisy Disk excels is two places: It's programmed to efficiently and using parallel processes rapidly search out all the special cases where Apple has filesystem ...

Although it's not directly related to the Xcode app size. There are multiple places where you can delete files to free up some space. 1. Derived Data Xcode keeps data about your projects which includes index, build output and logs. Go to ~/Library/Developer/Xcode/DerivedData/ and delete the folders for projects that you no longer need to keep this data ...

The answer relates to changes to Time Machine backups in Lion. My understanding is that when a TM back up is attempted when the back up disk is not connected, a back up is made in /Volumes/MobileBackups. These back ups do not go away the next time TM runs with the back up disk connected. I am not sure if the OS will eventually reclaim this space. You ...

Spoiler: I went from ~50 GBs free to ~277 GBs free, about 227 GBs difference, over the course of this answer.

Do you have Time Machine backups turned on? If so, the difference may be due to space used for "local snapshots" (essentially, backups to the local disk when your real backup disk is not available). Local snapshots are automatically deleted when the space is needed for something else (actually, it starts purging them when the volume reaches 80% full), so the ...

It scans your disks as quickly as possible and shows you the facts — if a file doesn't make the cut to stay, ...

I recently ran into this - on my 500GB SSD, my free space was only 5% where I expected more like 75%. I found an answer in a blog that worked for me: Apple state that they automatically remove local snapshots when disk space is low, but their definition of low is apparently only 5GB of free space remaining – not really much free working space in 2017 ...

I think Disk Inventory is as fast or slow as any of the others. If the disk is big, it's slower than on a little one, and of course, on an SSD it is really fast. Although it is from 2006, I think it isn't bad coded, and it still works on my 10.9. It gives more info than you need, but you can ignore that, as long as you find what you need. I guess what takes ...

Perhaps a more elegant solution would to be use the command line tools instead of Xcode. You could delete Xcode entirely (or skip the install). Instead of downloading and installing Xcode - open the command line (terminal app works out of the box) and type gcc. That will pop up a window where you can install the command line tools. Click install, click ...

Starting with macOS Sierra, macOS comes with an in-built app from Apple called Storage Management, which is a part of System Information package. In different tabs it shows you the largest apps installed, as well as a folder viewer with their sizes listed. A special tab shows the largest files over all of your folders, which I find very practical. To launch ...

You can simply enter Time Machine and select folders, apps, and files and select to delete all backup copies of that item.

Try sudo ncdu instead. As a normal admin or user you are not allowed to scan the content of certain folders (all indicated by an error while scanning and in the final listing by a dot - if a subfolder can't be scanned - or an exclamation mark - if the whole folder is excluded from scanning due to missing read permissions!). Examples (only the big six and ...

You'll need about 20GB free to do the install when you consider the space needed for holding/swapping files with the .dmg during the install process. I saw this in the app developer forum: Have a look at About This Mac → Storage tab. You might see a purple segment labeled "Backups." That's the local Time Machine cache, and it doesn't show up in ...

/Users/.harith/harith.sparsebundle is the encrypted contents of your home directory. When you are logged in (as user harith), then the unecrypted contents of that same directory are visible under /Users/harith, that is, your home directory. So what you're seeing is, your hard disk is full. And your home directory is taking up 178 GiB of space. IT IS NOT ...

Starting up from the recovery partition and repairing the disk fixed the issue. (Disk Utility showed an error about an invalid free block count.) Thanks @cksum.
