Error downloading macOS Sequoia

I had trouble downloading update as well. I Just bought new MacBook Air. I looked into the advise to Turn off FindMy. For whatever reason my FindMy was already off for my new MacBook. I turned it ON and download worked without any issues.

Turning off "find my" worked. Took me ages to find this, so thanks for posting.

macOS 13 or later: Choose Apple menu > System Settings, click [your name] at the top of the sidebar, click iCloud, click Find My Mac, then click Turn Off next to Find My Mac

Nothing seemed to have worked for me except this!

Open Apple App Store

Search for Seruoia

Get the app

It'll push a download without error.

I had similar problems downloading the new 15.0.1 Sequoia on my MacBook Air. I removed a number of items off my desktop and that worked for some reason. I tried yesterday 8 times, give or take, to download this new system. It failed every time. (There was nothing wrong with my internet connection). I remember my dad said that putting a lot of stuff on my desktop can be a bit "stressful" on the computer. So, I moved a number of things and the 1st time I tried to update this AM, it worked. No problems. Hope that helps. Cheers.

I think it worked finally for you because the error is random and it is retried enough times it finally works. So maybe tossing a cat over your shoulder would seem to work too.

What I did finally after trying everything suggested here was to give up and create a local bootable USB drive and then install it from bootable media. This method does not need an internet connection.

Clearly, the problem is that the server at Apple fails randomly.

I've run into this problem over and over. I tried almost everything posted here with no luck.

What has worked for me, I connected my VPN (nordvpn) and I can see and download the updates without problems.

Had similar issue, disabled find my, install directly from app store, boot

to safe mode and install from there but did not fixed the install issue.

I noticed the time was out of sync. The time server was incorrect, it was set

to “time.apple.com.”. Had to remove

the extra “.” at the end of the server address. Ones the time synced and rebooted then it worked.

Same here. Apple tech walked me through the same error. Had to go into Terminal and remove 2 lines. We typed in “ sudo nano /etc/host” Then typed in my password. Removed the problem lines. Works perfect now. Might call tech support. I got a great tech!!!! Now, download Sequoia OS and installed no problem. I have a new MacBook Pro with M3. Bought on Apple website refurbished. 11/5/24

I called apple support and they made me an appointment with the store to take my hard drive to the store and let them download Sequoia to my hard drive and they said that would work even tho I went to the App Store down loaded macOS Sequoia it would not work to many errors I have not been to the Apple Store at this time tho I will let you know if it works that way for me I do know this even the apple support said they are still learning about Sequoia them selfs and how it works

Try in Terminal:

sudo softwareupdate -iR --os-only

I don't know if this will work with Upgrades, though.

re: < --os_only > (?)

softwareupdate: unrecognized option `--os_only'

What I see in the man page for this flag:

 --os-only 

Oops. Fixed the typo, but it doesn't work. Seems to download the full thing before it fails, but it still fails.

Did you fixed? I went to apple store today regarding the same issue and told me to wait one month if they release new update to fix that. Are you aware of any other options?

Luckily and finally I found a way out, at least it worked for me. First I got my air m2 updated to 14.7 and then I went for the 15. It worked without any issues.

Thank you for sharing your Apple conversation. I am just going to wait until mid October and retry update. Apple should send us all an email notice about this known problem.
