Since installing macOS 10.12 I noticed a flood of messages from deleted in the logs. I haven't been able to find any information about this daemon. Could anyone enlighten me what this does?

deleted is the process for CacheDelete, which is used to purge caches on disk. Looking in /System/Library/CacheDelete/ you can see what services are registered as a client.

3This is a good starting point, but is crucially missing a way to troubleshoot further - I hit this issue with Catalina, and all I had in this folder were macOS's own bundled components. @vaughan 's answer below shows how to dig deeper with the Console app; I would add that similar can be achieved in commandline with
log show --predicate 'processImagePath CONTAINS "deleted"' --last 10m --info.– myxalCommented Sep 7, 2021 at 8:27
I came here due to an issue on my MacBook Pro (2018 15") running on macOS Catalina 10.15.7.
In fact, the deleted process was showing up in my process list and consuming around 50% CPU - more or less. After following some hints which I found here and there (deinstalling iStats, resetting SMC and so on) I realized that this process kept on being open as long as my About this Mac window was open. The deleted process disappears shortly after closing the About this Mac window.

20I had the exact same issue with "About this Mac" which I had left open in the background. Closing it immediately solved the issue. Commented Feb 5, 2021 at 9:06

1Thanks, the "System Info" window in the background was the culprit for me too! Commented Feb 28, 2021 at 10:06

3I didn't have the 'About this Mac' open, but I opened and then closed it. Now the deleted and IDECacheDeleteAppExtension processes finally stay gone. Before that I had tried 'killall deleted IDECacheDeleteAppExtension' and 'launchctl remove com.apple.cache_delete', to no avail. Thanks a lot!– Jonas NCommented May 20, 2021 at 13:57

1Opening and closing the "About this Mac" dialog fixed this for me too. Very strange!– FransCommented Aug 25, 2021 at 18:26

Thank you for sharing this solution. I thought I had deleted a Fluid Browser app (hence the deleted_helper) which was still running in the background. I couldn't understand why it kept restarting after being forced quit. Commented Sep 23, 2021 at 13:34
For me, this problem was being caused by problems with iStat Menus on macOS Sierra 10.12.0. There seems to be a bug which causes issues with the deleted process. Once I uninstalled iStat Menus the problem ceased.
This issue has been resolved, see https://bjango.com/help/istatmenus5/knownissues/

3I had the same problem and tracked it to iStat Menus. But instead of uninstalling it completing, I fixed this just be disabling iStat's "Disk" menu item and then doing a global restart of it. This totally fixed it. I think what's happening is that iStat Menu is just asking macOS for the amount of purgable disk space every ~10 seconds and that's what's causing the extra stress.– ChrisCommented Feb 11, 2021 at 0:32
I found that the deleted was activated when I started the Disk Utiulity and selected disk container which has macOS system.

Confirmed this on Catalina. I have Disk Utility open constantly, so
deletedwas taking more cpu time than any other process. My workaround is to mount a read-only dmg and keep that selected instead. I also use AppPolice to limit cpu just in case.– KelvinCommented Feb 1, 2021 at 4:46
In Console.app search for deleted and look for an entry like this:
default 17:23:45.621668+0100 deleted 1426 com.apple.deleted_helper APFS Purgeable update for Calling process: iStat Menus Status on "/Volumes/ExternalSSD2TB - Data" ET: 1.452986, results:

default 17:23:45.622984+0100 deleted CACHE_DELETE_ELAPSED_TIME : 0.145932097
The line CACHE_DELETE_CALLING_PROCESS : iStat Menus Status reveals that the iStat Menus Status process is causing the calls.
This issue started occurring for me when I activated the Disks option in iStat.
After removing unchecking this option, the issue still occurred, but after I killed the iStat Menus Status process from Activity Manager (I also killed some other ones too), the deleted activity went away entirely.
Looks like an iStat bug.
On my recent M1 running Monterey I was trying to rename a directory but got a notice that it couldn't be done because 'another operation' was in process. Running Activity Monitor showed the 'delete' process running with CPU% hitting about 30%. Tried a few solutions offered here but none worked. Relaunching Finder did the job.
deletedstill shows up every now and then, but it doesn't consume as much as a core anymore (from 25% to around 0.4% for me).
