MacOS has an option to automatically delete files from your Trash directory after 30 days. If Apple had used this directory instead, its App Store mistakes would have been deleted within a few days. Files that aren’t opened or used in the DARWIN_USER_TEMP_DIR directory (different from DARWIN_USER_CACHE_DIR) are automatically deleted after three–four days. There’s a more appropriate directory to stage downloads in, however. For whatever reason, I found partially downloaded versions of Xcode that had built up in this directory going back years.

As it turns out, the App Store downloads into this cache directory before moving the completed download into place on the disk.

I also found about 130 GB of failed Xcode downloads in a subdirectory belonging to the Apple App Store app.

I even found some software trial-license control files hidden away there as well. In exploring my DARWIN_USER_CACHE_DIR directory, I mostly found cache automatically generated by MacOS on behalf of third-party programs. Everyone seems to stick to the ~/Library/Caches/ directory instead. The directory is under-utilized in modern versions of MacOS. They can be anything anywhere on your system disk. The Storage Management app doesn’t provide any details on what or where these “other” files are located. The files in the DARWIN_USER_CACHE_DIR directory accounted for 135 out of the 174 GBs of “other” files reported by the Storage Management app in MacOS. Each user account on your Mac has its own DARWIN_USER_CACHE_DIR directory. Its location isn’t a secret, but you must execute the getconf DARWIN_USER_CACHE_DIR command in the Terminal to find where it’s located. It’s a hidden cache directory that’s located outside your Home directory. Then there’s another “user cache” directory called DARWIN_USER_CACHE_DIR, a relic from the early days of MacOS.

It’s well-known in the Mac professional community. Many online tutorials will advise you to quit every program and delete the contents of this cache directory if you’re running out of storage space. You safely delete these files without losing any valuable data. Cache files are generally not considered to be valuable. The directory is excluded by Time Machine and other back-up programs.

Cache files are files that programs can recreate by redownloading them from the internet or by performing a local operation on another set of files. This directory is where programs are supposed to store cache files. The “primary” user cache directory is stored in ~/Library/Caches/ directory in your Home folder. The rest of this article explores where to find this directory, what it’s for, and what Apple can do better to prevent this from happening. It was all taken by junk files stored in my hidden DARWIN_USER_CACHE_DIR directory. Upon closer inspection of my disk, however, I found where the missing storage space had gone. The problem began when MacOS migrated to the Apple File System ( APFS), and everyone and their pets attributed the problem to vague APFS related issues. For over a year, I wrongly attributed the storage space to unicorn file-system features like snapshots.

However, I couldn’t account for about 130 GB of storage space on my Mac. I checked every file and directory, and used various apps to assess what took up my storage space. So, where did the storage space go? and how is it all Apple’s fault? My MacBook only has 250 GB of storage, but 130 GB of storage space went missing for over a year.
