Well? Have you updated to iOS18 or Sequoia? What’s it like? So far, so good?

I’m finding Sequoia to be way more problematic than Sonoma, which I upgraded on day one and I have no recollection of any problems.

I waited until Sequoia 15.1 to try and avoid initial bugs, but…

  • Spotlight was broken, and therefore Alfred did not work. I had to rebuild the index twice. It seems to be stable now (fingers crossed).
  • Memory leak galore. Spotlight, spotlight knowledge, mds_stores and other system processes were consuming way more RAM than what the system has, constantly using swap memory. During the memory spikes, Spotlight stopped working. I had to disable all apps in Apple Intelligence & Siri and do the aforementioned index rebuild for it to stop (again, fingers crossed).
  • And the worst offender: com.apple.mediaanalysisd cache is creating a new 67.9MB file every few minutes, non-stop. It’s consuming GBs every day. I’ll run out of space very soon if this isn’t fixed.

Both that cache and the Firefox Cache were hitting the 1 GB shorty after I would clear them out. And I rarely use Firefox.

Not sure why that was happening but it’s calmed down now and I’ve been on 15.1 for about a week. I hadn’t cleared those files out in a few days and just checked. Firefox is at 162 MB and the mediaanalysisd is at 132 MB. I assumed it was 15.1 that fixed that, but you’re still seeing that large file?

Yes, I am. Yesterday the file was 47GB, today is 48.3GB.
I’ll delete it and see what happens.

I’ve not experienced bugs quite as bad as others on Sequoia yet, but I was eager to upgrade for iPhone control. So I did the .1.

A few bugs. I had to re-index Spotlight. My Docker VMs really don’t seem to like certain configs.

But some of these bugs also appear to have found their way to Sonoma too, which is why I upgraded. If I’m going to have issues with the old OS, I might as well have them on the new one instead.

I don’t know much about what that file does but it has something to do with your Photos catalog, face recognition, Photo Search, and Spotlight indexing of photos. I’m hoping if you delete it and it starts the rebuilding process it won’t be as large, which is what I saw.

Is your Photos library really large?

After I deleted the cache folder, it doesn’t seem to be growing out of control anymore. I’ll keep monitoring it.

I don’t know what really large means to you, but my library has around 40,000 items (photos+videos).

I hope that it stays at a reasonable size.

And I guess I don’t know what really large means for me. Mines about 2500 photos – that would certainly explain why the size of the file was so different in pure GB. That and I deleted mine every few days. I haven’t deleted it once since I moved to .1.

Good luck! I hope it doesn’t go out of control again.

I’ve had issues with my fan cycling up since I upgraded to Sequoia, and occasionally I’m getting the spinning wheel while typing and I have to wait for my Mac to catch up. I know I’m on an Intel Mac and it’s probably nearing the end of its usefulness, but nevertheless I’m finding it quite irritating. It’s kind of reassuring to know others are noticing problems with Sequoia!
