macOS Big Sur Installation Failed: 'An Error Occurred While Installing the Selected Updates'

[MacRumors]

Apple this morning released macOS Big Sur to the public, and since the software went live, it has had extremely long download times that have prevented many from being able to install it.

Even those who have made progress through the download have run into problems where the software downloading process is suddenly interrupted and must be restarted. Others have reported being able to download the update and then having the installation fail. Apple's site appears to be having some major issues due to the number of people attempting to download the update at once.

In addition to these Big Sur download problems, Apple's developer site is also down at this time, and as a result, some third-party apps are unable to be opened up at this time.

An error occurred while installing the selected updates


It's not clear what's causing the problem. It could be that the macOS Big Sur downloads are failing due to a developer site issue or the developer site could be failing under the strain of macOS Big Sur demand, but it is clear that those hoping to get the new software should hold off until things are more stable.

Apple's System Status page is listing an issue with macOS Software Updates and says that the problem is "currently being investigated."

Ugh, not just the dev site. Store is down too. And not in a good way.

Also, one can't even reinstall macOS by using CMD+R and entering recovery.
This is pathetic Apple.

Anyone wanna buy a MacBook Air? Oh, wait...

UPDATE: Dev site up again. Went to download Big Sur on the dev site... what the?!

Download button took me here. No joke...

Pathetic.

Netflix, etc, can handle the load when a new movie or TV series is dropped. You'd think Apple would've figured this out by now.

Yup. I knew something must have been wrong. My installation would progress only up to about 3/4, and then would fail. I wonder what's going on. I know some people were able to download it.

 

[Bustycat]

Many people’s downloading failed.

Another **** OS brought to you by Apple FFS

My machine can no longer run any 3rd party programs after a restart after several installation failed notices during download.

In other news, Apple Buys Netflix... ?

I can't install Big Sur at all. All I get is an error.

 

[darkmatter343]

The store is down too

Maybe if they had work towards delivering smaller updates and splitting the download into multiple packages, it would have been easier.

Yes this was exactly what I was seeing

I didn’t know what the heck was going on with my machine. I wasnt even trying to download Big Sur. Wow. This is crazy. Hope it gets fixed soon!

not to mention the OCSP bug that is preventing people from just using their laptops. apple's incompetence is astounding.

here's a workaround:

Apple just DOS'd every single mac for almost 10 minutes. This is the bigger issue. I shouldn't have to check-in to an Apple server every time i want to launch Microsoft Word.

How is this OK?

(no, i didn't have a failed install)

You'll progress to the error phase of the installation process shortly

What I hope MacRumors picks up on really quickly is that users including myself, are experiencing serious graphic hiccups on their machines after failed downloads!

We have 11.0.1 and we think Apple pulled it. All our computers at our company are experiencing Application Loading slowdowns and in some cases the computers are unusable. See our post: https://discussions.apple.com/thread/252030371

We had posted previously on the Apple Community and they removed it. That link is our 2nd attempt. Something isn't right?

Many iPhone mini and max preorders got shipping information too, which I imagine is adding mightily to store traffic.
