New MacBook Air is not showing option to allow iphone notifications

Has anyone tried turning off the iPhone notifications feature before running Migration Assistant? And then turning it on on the target Mac after migration assistant is done?

I'm also having this issue. Got a new M4 MBP, everything was working as it should while I was using it for a couple days - iPhone notifications coming through. As soon as I managed to get my old laptop backed up and transferred across using migration assistant (like pretty much everyone else in here), it's completely stopped working.

It's really annoying to see apple still hasn't figured out a solution for this yet.

Right - we tried that too, and even when I did, my iPhone was still linked to my other user account and wouldn't let me double up on connect users.

New MacBook Air M4 15 purchased few weeks ago. I have connected my iPhone mirroring, but I do not have the setting (in System Settings | Notifications) that says Allow notifications from iPhone. It’s just “missing”. iPhone mirroring works fine. I have followed all the Apple setup instructions and all the articles I can find in the Apple Community.

Exact same thing for me too - went from an M1 Max 14in Pro to the new M4 Air 15". The notifications worked great on my M1 Max, but am completely missing the toggle for iPhone notifications in settings. Tried a couple things with an apple service worker but nothing worked. Submitted a support ticket that same day and haven't heard back yet. I noted too that both phone and computer were running the Beta's of their software, but now that 15.4 and 18.4 have officially come out today, the issue is persisting through the official release.

I also applied updates 15.4 and 18.4. I still do not have the Allow notifications from iPhone setting although I have iPhone mirroring configured. @shawn5574 please let us know what support says. I too contacted support and their solution was create a new user. That is not an option.

I'll also add that I transferred all of my data from the M1 Max 14" to the new M4 Air 15" using a thunderbolt cable instead of setting up as a new mac. Had too many items I wasn't interested in trying to reinstall after set up so I opted to transfer. Not sure if there was a line of code that got all wonky during the transfer or not, but I thought I'd add this to the thread.

Same. I transferred mine from a MacBook Air M3 to MacBook Air M4 using a thunderbolt cable instead of setting up new Mac also. Too much data, also wasn’t interested in reinstall apps and copying data. Didn’t want to take the time. Notifications worked on the MacBook Air M3 and the toggle for Allow notifications from iPhone was also on MacBook Air M3.

More testing after upgrading yesterday to 15.4 and 18.4. And I found the following: I too, am able to search in System Systems for “iPhone” and can toggle on Allow Notifications from iPhone, but after closing System Settings and reopening, the toggle and statement for Allow Notifications from iPhone is gone. I do not receive any notifications from iPhone on my MacBook Air M4. iPhone mirroring works fine. So does Hand off.

Interesting. When I create a new user account I can't connect to my Iphone at all. Did you have to log out of iCloud in your main account?

Anyways, that's a lot of work just to fix this issue.

It seems everyone here has used Migration Assistant, so I agree with you that it might be the cause of this bug.

experiencing the same thing right now.

migrated via thunderbolt from my m1 air to my new m4 pro. It must be a bug or something because I re-installed sequoia and that didn't fix it nor re-signing into my iCloud account.

I assumed this would be a resolution.

However, this is not practical for me. I have over 100GB of data to migrate. That is why I used MA to copy the data from one MacBook Air to another New MacBook Air. I firmly believe this is an issue/bug/glitch that Apple NEEDS to resolve; especially since I used Apple's "built-in, already loaded on their devices" MA that ALL Apple's documentation and the SA encourage to you use when setting up a new Mac device.

I updated to macOS 15.5 RC in hopes that they might finally have snuck in a fix, but sadly, nope. Same thing, setting is there if you search for "iPhone" but it seems to do nothing and doesn't stay on once you close settings. Apple has gotten way too sloppy lately..

Do we know for sure that this is affected by both Time Machine restores and Migration Assistant? I believe I used the migration assistant that popped up to migrate from my MacBook Air to my mac Mini. I'm just wondering if anyone has tried a full restore from a Time Machine backup and has the same issue?
