The options for fsck_hfs have changed, but it seems like this cause of hidden space is different than before. This mysterious missing space bit me again recently. I’m delighted because I was this close to shlepping my files off to a USB drive and reinstalling the OS. Now the missing space is a reasonable 3.5G, and I am now led to believe that is, at least in part, the catalog file and other filesystem mapping files, which are inaccessible to user-space utilities. Just for paranoia, I ran it again and everything came back clean (except that odd warning afterward…I’m ignoring it): You can see how many times it tried to fix things. When I rebooted to try to free up some space, it took forever to come back up, but when it finally did, all the missing disk space was back and I now have 85G instead of 18G left.įor good measure, I single-user booted again and reran fsck_hfs: Now after a single-user boot, I tried rebuilding the catalog file on /dev/rdisk1 (the raw device representing my encrypted hard drive volume) using fsck_hfs -Rc -y /dev/rdisk1 and it bailed out with an out of disk space error. Hey everyone, Im using an app called DaisyDisk to clean up my HDD - the thing I dont get is, why the s dont add up The app says Ive used 168gb, meanwhile I only see about 90gb worth of data underneath. I remembered fsck from my happy FreeBSD days, so I thought I would single-user boot and run an fsck_hfs to see what might come up, but first I needed to figure out which disk was the right one to scan Disk Utility helped with that: select the primary volume (mine is the default “Macintosh HD”) and notice the “Device” in the bottom left corner: disk1 Adjust the 50GB in the illustration to whatever size you deem appropriate. I haven’t ever seen anything like this before. Search with Finder to see if the space is being consumed by a very large file or several large files. I have an encrypted boot volume and thought that perhaps something had been corrupted, but I wasn’t sure. Scanning with Daisydisk returns with results as above, with a 'still hidden' part of space taking more than 40 GB. No scanner could detect where it had gone (DaisyDisk, WhatSize, Finder, “About This Mac → Storage”, Disk Utility (also in Recovery mode), command-line utilities df and du): they all indicated that there was only 18G left and none of them could tell me where the missing 69G was. 1 On my Mac running macOS Catalina, I noticed there were much less and less free space during past several weeks in which I had done little file additions or software installations. Click the System Apple top left, then "About this Mac" and then "Storage." Breathe a sigh of relief.For several weeks I’ve had a 69 GB chunk of disk missing. In Terminal paste defaults write AppleShowAllFiles NO.Look within the folder Macintosh HD/.DocumentRevisions-V100/ (For me there were a number of underlining folders with lots of files within.).You can hold down "Option" and then right click Finder. Finding & deleting these unwanted files to recover disk space manually is quite troublesome especially when the files are hidden. Paste defaults write AppleShowAllFiles YES (This makes all hidden files visible) DaisyDisk succeeds in making it pretty simple (and actually somewhat fun) to track down and eliminate space-hogging files on your Mac.It appears to be from documents primarily from the app Sketch. Navigation is a snap: clicking on a section of the display zooms in and creates a new circular layout showing the chosen files in more detail. The display is color-coded, so you can easily distinguish between different types of data. These are document versions which the OS autosaves ( more info). DaisyDisk uses an innovative circular design to show you the different files taking up space on your Mac. ( Instructions) I found 187GB in the hidden ". Click on any of these segments and DaisyDisk will allow you to dig deeper into its contained folders and files until you find out that large file you are looking for. ![]() I scanned my drive with DaisyDisk, and as an administrator.
