I am on macOS 15.2 and at present I’ve simply found a really unhealthy behavior for idleassetd: an enormous reminiscence leak when working offline.
My state of affairs is: display savers disabled, static background, and dealing principally offline.
I restarted my MacBook Air M1 and opened Exercise Monitor within the reminiscence pane; idleassetd began coming out with a really restricted utilization, however then it grew up and after a couple of minutes is now utilizing 21 GB of reminiscence (principally swapped)!
Whereas scripting this few sentences, the quantity has already modified to 23.00 GB.
This occurs when idleassetd is offline, so when my machine shouldn’t be related (actually offline) or after I block it to achieve the community (I am utilizing TripMode, however every other method reveals the identical habits).
What’s taking place is that within the subsequent 30 to 60 minutes my exhausting drive can be totally used, and my Mac will crash and reboot.
If I am going on-line the reminiscence utilization stabilize (however would not lower if I do not reboot), however then the software program downloades a number of gigabytes (like described in different posts like idleassetsd going loopy).
Only for completion: the software program can be writing gigabytes and gigabytes on my SSD, each when on-line and offline, consuming my SSD.
I’ve tried all the answer discovered to disable it for the reason that disk and community utilization is a well-known bug from macOS 14, whereas it is the primary time I learn concerning the reminiscence leak, however none was working.
Thanks all for any thought or suggestion.
ps: now 25.7 GB and counting…….
Replace 1: I’ve reported it to Apple.
Replace 2: What I’ve tried to resolve the problem thus far:
- numerous reboots (compelled and “pure”)
- eliminated recordsdata within the /Library/Utility Help/com.apple.idleassetsd folder (and rebooted)
- chosen the Sequoia screensaver for all accounts – commonplace, not animated (and rebooted)
- disabled the screensavers activation from all accounts (and rebooted)
- enabled the Sequoia background on all accounts (and – guess what? – rebooted!)
- killed the method
- deeply searched on Google, Reddit, StackOverflow and different sources
