How did you find that? And how did you solve it?
You'll need to open Activity Monitor, switch to the Disk tab, and search for "corespotlightd" and have a look at how much data's getting written by that process.

I had an absurd amount one time I checked, like 800+ GB. I also noticed that my computer would feel physically hot even when there was no reason for it to.

To disable, you have to also disable SIP. Simply unchecking all of the spotlight options, or disabling in through other means won't stop the spotlight process.

Supposedly it'll probably go away if you also reinstall the OS from scratch, but I'm a developer and have signing keys all over my machine for a bunch of different projects, so that's a nightmare.


I’m also interested in this, and if it’s happening on external SSDs like the Samsung T5/T7, or on NVMes inside a Thunderbolt case.
There's a way to move the spotlight index to another volume (other than the boot), so theoretically yes. Basically this bug seems to just write and rewrite stuff to the spotlight index over and over again, as fast as it can, which is AWFUL for the life of your SSD. Especially when the storage is soldered/integrated like they are on most Macs.

I hate having SIP disabled, but I can't afford spotlight trashing the SSD in my MBP. I disabled and switched to Raycast.

Just updated my ipad pro m4 and now my internet is broken. No lan, no wlan no hotspot is working.
Now I can’t even fall back on my backup, as it is in the cloud! ?
Yes, I have done the usual, toggle wifi on/off, turned ipad off…
Anybody?

Edit: after some searching found a post from a different update. They suggested deleting incompatible certificates and VPN profiles. In my case that was NordVPN. Deleted it and instantly the wifi-connection was restored.
But I did learn something: keep a backup on the device, not only in the cloud!
This happened to me too on my iPhone 12 PM. I was wracking my brain trying to figure out what went wrong, tried restoring with my MacBook, but since there was no internet service on the phone I couldn’t remove Activation Lock to do the restore, spent some time being mad that I was gonna have to buy a new phone because I wanted the 12 to last until Sept and the 17s, then I also found something that mentioned VPNs. Removed the NordVPN profiles and instant success. I even tried letting the app install the profiles again and it broke it again. I don’t know enough to know whether the fault lies with Apple or NordVPN, but it would be nice to have a fix.

Will 15.4 finally fix the spotlight bug that writes hundreds of gigabytes of data to my SSD every day? Seriously, I had to disable SIP to completely kill the corespotlightd process, absolutely absurd.
