Downloaded 12.18 GB in an hour and it got stuck for next half an hour and gave me error "an error occurred while installing this update". Restarted the upgrade again, got stuck at 2.44 GB for 15 minutes. Rebooted my mac and started the upgrade again and got stuck again at 2.44 GB (attaching the screenshot).
MacBook Pro Early 2015 running with Catalina 10.15.7
MacBook Pro 13″, macOS 10.15
Ok got it working and downloaded
These are the steps I did.
Deleted the following:
Go to
Library
Preferences
Delete “com.Apple.softwareUpdate.plist”
Empty Trash
Restart Computer
Select The Apple Top Left
Go to about this Mac
Select Software Update
Just got off the phone with Apple Support. The issue is still persisting, and they said all we can do is wait for the issues to be ironed out. "Wait an hour or two and try again" is the advice I was given. The System Status page hasn't been updated to reflect this yet
No, just a straight download from Software Update. I had about 3 different download sessions, since 1pm 0-2.6Gb then 2.6-3.4GB a short 3.4-4.0 and long long error wait error wait then finally around 8pm ET 4.0Gb to full install.
Same problem here. Macbook Air 2015 model.
I even downloaded the Big Sur installation from the Mac App Store using a Macbook Pro 16" 2019 model running the latest Catalina update.
Created a bootable USB installation drive of Big Sur.
Booted the Macbook Air from USB and ran the install. Still get the same issues presented in your screenshots.
Currently creating a Catalina Bootable USB Drive and reinstalling that. So far this has been a **** of a rid on friday the 13th.
I am surprised this isn't even solved yet especially for a company with Apple's magnitude.
I got the same message and I had 30gbs left of space on my macbook air
Looks like Apple are working on it. Best bet seems to be keeping an eye on their System Status page to see when the issue gets resolved
My guess is that the issue, which is a missing pkg file, needs to propagate throughout the CDN before we're able to finish the installation.
This user has just posted the installation link which worked for me without any issues and for many others https://twitter.com/fuolpit?s=21
so did you do it?? did it work?? please tell me
The software update from Catalina to Big Sur is now working. I clicked on Apple, About this Mac, Overview, Software Update. It's slow, but it works.
There is nothing wrong with this link
I am allready running macOS Big Sur if you want that is tonight you better click on that link duck
Mine is working now, it looks like it has to propagate to all of the servers
??
Just started after retrying a million times...
yes
