Try going to the Apple Store on your computer and search macOS Sequoia, then select "get it"
Ok so it has been downloaded, but an error as occur in the installation, so now I’m back to square 1 with 15Gb hidden files that I need to delete !!!!!
This time it was not in the Mac OS install data file but in a clean application for Sequoia installer so it was easier than I though.
Brooo.. same sh... just happened to me. it was installing then boom, failed to connect etc etc... OMG..
I'm having the same issues. It's pretty infuriating. Although apparently Apple has a fix for it sometime this week according to someone on reddit. Anticipated to arrive this week. So I guess we will see.
I would try creating a new user in Settings/Users & Groups/Add User... Log out of the current user you are using and update from the new user account.
I had this issue with an M1 mini going from one of the betas to the release candidate version (which is the same as the final release.) To fix it I had to put the mini into DFU mode and use another Mac and Apple Configurator to revive the firmware on the mini. Once that was done, I was able to install the 15.0 update without error.
Nice, but we shouldn't have to fuss around and waste our time with all that just to install or update our OS. This is entirely ALL on Apple. And some of us don't have the luxury of having more than 1 mac. Such a PITA really. Never had so much problems trying to update macOS before. This is a first.
Im having the same issue! made an account just to post this. I just bought this m3 pro 1tb storage and 36gb with my own money (im a teenager) this month for my hobbies and work, and first my cable didnt work so I called online and was on the phone for 3hr and finally got replacement and now ts happens? not putting a good impression for my first apple computer. get it together apple
The Link didn't work, Thanks for sharing. Hopefully Apple will fix this. I have a 2023 MacBook Pro
It didn't work for me either. I thought it did at the time I posted that. Sorry for that
Seems a lot of us are having this issue. I assume and hope Apple will address it over the next few days. We'll just have to be patient
I’m having the same problem. Purchased my MBP M3 Max less than 2 weeks ago. I’m guessing by all the posts of different supported Macs, that this must be an Apple issue. Hopefully they will have it straightened out within a couple of days.
Update: I followed the list from the WiFi on and off to the forget network and establish it again. I booted into safe mode and downloaded Sequoia but when it came to installing it, ” an error occurred preparing the update, failed to personalize the software update”. I figured I would run through the online Apple support. I tried to reinstall Sonoma from recovery but had same error. I erased my drive and went into recovery. When it got time to put in for the activation lock password (because this fool forgot to turn off find my device) it failed activation. So long story short I took it in to the Apple Store I originally bought it from, and they hooked it up to their MacBook. Had me delete my device on iCloud and rebooted Sonoma for me. It was done pretty quick. I’m home and the update to Sequoia seems better than before. It finished and restarted and currently watching it update. Finally! It booted into Sequoia.

Hello guys,
This solution solved my issue.
I turned off my Wi-Fi.
Then turned it back on.
Then shut my Mac down.
Switched it back on.
Opened the Mac App Store.
Selected MacOS Sequoia and clicked on Get.
It redirected me to the System Settings and started downloading the MacOS Sequoia.
I tried to update my Mac Book Pro M1 to macOS Sequoia, but I kept running into an error: "failed to personalize the software update." It was incredibly frustrating, especially since I tried every common troubleshooting step without success. If you’re facing the same issue, here’s what happened to me and how I finally solved it.
One thing that caught my attention was that the download size for macOS Sequoia through the Software Update menu was 6 GB, but when I downloaded it through the App Store, it was a much larger 14 GB. I’m not entirely sure why this difference exists, but after downloading the larger version from the App Store, the update also failed. No solution found.
I tried:
- Restarting my Mac multiple times
- Switching networks to see if that was the issue
- Ensuring that storage space wasn’t an issue
Use the App Store
After a lot of trial and error, I found a solution that worked for me. Instead of using the Software Update menu in System Settings, I went to the App Store. Here’s what I did:- Opened the App Store.
- Searched for macOS Sequoia in the search bar.
- Instead of downloading it through the update section, I clicked on "Get" next to macOS Sequoia.

I also downloaded the stand alone update but it did not work for me I still get the error.
Software Update downloads what is required to update your specific Mac from its current state. The download through the App Store (and other sources) is the complete macOS 15 with everything needed for any Mac to install to a blank disk.
I was able to upgrade my MBP from 2018 yesterday but my MBP M3 refuses to udpate. I've tried both ways, via system settings and app store.
