Apple Intelligence stuck on "Preparing" status for more than 10 hours

On my M3 Macbook I have been waiting for it to fully download since day 1 of the availability. I have been on WiFi the whole time. I’ve switched from 5ghz network to 2.4ghz and back. I have switched languages, rebooted and switched back. I have switched with rebooting. Region is correct. Languages is correct. My internet connection is 300-400Mbps. I get at least 200Mbps on WiFi.

4.43GB and holding.

Maybe I should try ethernet.

After being stuck for nearly two weeks, I went ahead and did the following which worked:

1. Backed up to Time Machine

2. Used Disk Utility to erase the drive

3. Used Recover Utility to reinstall macOS (Sonoma)

4. Updated to the latest macOS Sequoia 15.1.

5. Verified Apple Intelligence was installed and working.

6. Used Migration Assistant to transfer my info from Time Machine.

I updated to 18.1 on release day and am still waiting for apple intelligence on my MacBook Air M2.

Tried changing the language to an unsupported country and back, restarted multiple times, re-installed Sequoya all to no avail.

My M3 Max MacBook Pro has been stuck on Preparing... for weeks. Trying the solutions here hasn't worked for me yet, but I did notice that while choosing voices, some of them will download for me, like Premium Zoe, but none of the Siri voices will start downloading. They are all stuck at Zero KB, even though I am connected to a very fast WiFi network. I have a feeling that whatever is keeping the voices from downloading is holding up "Apple Intelligence."

Same thing here. We bought a new M3 MacBook Air expressly for the Apple Intelligence features, but the install is still stuck on "Preparing" over more than a week. I had hoped the Sequoia 15.1.1. update would address this, but it has not, and that is extremely annoying. None of the fixes mentioned in this thread have worked. Let's get this fixed, Apple, and soon!

By the way. it installed in a flash on my older M1 MacBook Pro. Go figure.

Mine has been stuck for weeks. Somebody commented in here about the size should be 4.94. Mine is 4.91. I am not sure if that means anything, but when I have time perhaps I will back up time machine wipe out and reinstall. i did do the upodate last night also

Both of my 15.1.1 systems show Apple Intelligence at 2.49GB. Both were working properly for several days but now one has returned to the Apple Intelligence is downloading dialogue. Have tried all recommended solutions except erasing and reinstalling with no luck.

AI still stuck on PREPARING for my new iMac after 4 weeks. Tried all the fixes mentioned here and everywhere. When trying to set the language to ENGLISH (United States) Receive an error message that says: Settings Error Extension process Siri (43502) exited. After spending an overpriced amount for theNEW iMac, I did not expect to have ANY issue. Suggestions???

Has ANYONE discovered anything that works? I do not get why Apple, with all this new "intelligence," cannot fix this problem. That's weird. My M3 MacBook Air has been "preparing" for weeks. Tried every suggestion I've seen. No change.

Doesn't work on my Mac.

Same issue even after rebooting and verifying network connection.

None of the remedies in this thread have worked for me. Still stuck preparing.
