macOS Sequoia can be deferred for 90 days with a configuration profile.

The easiest way to create it is with the free iMazing Profile Editor https://apps.apple.com/app/imazing-profile-editor/id1487860882

Add the restriction payload, check “Defer Major OS Software Update” and enter 90 in the “Deferred Major Software Updates Delay”. In the General section select Payload Scope – System and Target Device Type – Mac. Save the profile (mobileconfig file) and install it.

Thanks! This worked. I am running Sonoma and the Sequoia notification is now gone. However, I do want any notifications about Sonoma. Will I receive Sonoma notifications?

Yes, you will receive notifications and see Sonoma updates in System Settings - Software Update.

May I know if this works for Intel chip MAC?

Thanks

I'm beginning to think that it does not. It worked on both of my Silicon machines but not my Intel. My Intel does have OCLP installed to run Sonoma. Apple does not support my 2017 Intel iMac and Sonoma. So, I had to install OCLP. I don't know if the Intel chip or OCLP prevents this mobilconfig from working. I'm anxious to hear OP's response too.

OCLP probably made some sneaky hacks that prevent enforcing software updates as described in Apple's documentation.

Ok thanks for the response. I'll poke around OCLP and see if I can find a way to make your config work.

@bogdanw I saved your config as delayedupdate.mobilconfig and as I stated earlier it worked perfectly on my Silicon machines. Here is the message I get when I try to install it in my Intel iMac OCLP. Do you have any ideas on how I can make it work? I know you probably are not an OCLP user but I figured it didn't hurt to ask.Image 9-26-24 at 9.40 AM.jpg
 
OMG!!!! Never mind!! I got it installed!! The problem was the location where I had the config filed stored. I placed it on iCloud to allow me to access it on any device. For some reason my OCLP machine had problems installing from iCloud. On a hunch, I copied it to my downloads folder and it installed. I checked and the Sequoia notification is gone! Yipppeee!!

Ignore update for macOS 15 Sequoia for 90 days:

https://forums.macrumors.com/threads/ignore-sequoia-for-90-days.2436999/

this does it for me. (1) open TexEdit, (2) copy paste "Code:", (3) save as delayedupdate.mobileconfig (4) before that I [ ] unticked the box that says If no extension is provided, use".txt" and I left it as Unicode (UTF-8)

save on desktop

then open System Settings, type profiles in the search box

under Install, view or remove configuration profiles, click the + button find the file on desktop named delayedupdate.mobileconfig

click Open then continue. Done.

I'm embarrassed but too curious to stay quiet. What is this profile trying to address? I haven't upgraded to Sequoia and it's not being pushed to me and I'm not being alerted to it being available. I do see that it's available if I navigate to software updates in system settings.

Since few days, and I already have the profile installed, I get a pop up telling me there is an update available, without saying what it is.
I check but of course I get the notification
"Your Mac is running the latest software update allowed by your organization."
LOL... but it starts to be annoying
 
I've yet to receive any alert or notification that Sequoia is available. System Settings shows that I can update, but that's the only evidence of it. I've not installed any profile.

When I did once did receive a notification and saw that Sequoia was available, there was also a Sonoma update. I applied the Sonoma update and that turned off the notification. It has not come back.

I do wonder what Apple's intended behavior is.
