macOS 15.2 Apple Intelligence Is Stuck at "100%"

[Takuro]

Moved to the 15.2 final release. Apple Intelligence won't finish setting up. It claims to be at "100%" but never actually transitions out of the downloading state in Settings.

I can't find any similar reports of this behavior. I see in earlier betas, people were fully clearing "/System/Library/AssetsV2/" -- I did this, and although it allows the data to be rebuilt, it still fails. In my case, within "/System/Library/AssetsV2/", it seems that after 30 minutes or so, "DownloadDir" grabs about 300MB worth of data via this directory, and then it just stalls out once that finishes, and "DownloadDir" then stays empty forever while "100% complete..." shows for hours without end.

I'm connected to both power and WiFi as it asks me to. Any ideas?

Going through the same thing on my MacBook Pro. Everything was working fine in the 15.2 betas, but now I’m back to old Siri. The funny thing is, even though it says it’s still downloading I have access to some features like writing tools. I switched the languages a couple times and got it to work, but as soon as I switched back to English (Canada) it gets stuck downloading.

Same issue here as the original poster. It's been this way for weeks now! Help!

Since Apple Intelligence came to EU with 15.4 I've got the same problem, stuck and spinning at 100%...
